DRILL PIPE
Drill Pipe Design and Manufacturing
Design
Drill pipe life is extended by creating a design that is inherently
fatigue resistant. When drill pipe rotates in a bent condition,
alternating tensile and compressive stresses can cause fatigue
cracks that may ultimately result in drill pipe “washouts” and
failure. Stresses tend to concentrate in areas where geometries
change rapidly. The shorter or more irregular the transition, the
higher the stress concentration. Alternately, the longer and
smoother the transition, the lower the stress.

The weldneck/upset design incorporates a counterbored

optimum stress-reducing geometry.

Pipe Body
Wall
Thickness
The thick weldneck, required for adequate weld strength and
the short internal upset of a standard industry design
concentrates stress in the adjacent pipe body.
DRILL PIPE
Geometry
The critical section of a joint of drill pipe is the transition from the
pipe body to the tool joint. This section consists of the weld that
joins the pipe and tool joint, and the transition from the thin
cross-section of the pipe to the thick cross-section of the tool joint.
The challenge to the drill pipe designer is to ensure that the weld is
stronger than the pipe body and the transition between the pipe
body and the tool joint is as seamless as possible.
Grant Prideco’s weldneck/upset design was engineered to
maximize fatigue resistance in this critical transition. A geometry
that minimizes stress concentrations is employed. The assembly is
configured to optimize the transition from the cross-section of the
pipe to the tool joint. The length of the internal upset is extended,
producing a shallow fade-away angle that blends into the pipe
body’s inside diameter with a liberal radius. To further improve
fatigue resistance, the surface finish of the assembly adjacent to
the weld line is improved by grinding on both the inside and
outside diameter.

The increased hardenability of Grant Prideco’s proprietary tool joint material
provides more consistent mechanical properties through the tool joint sections,
such as the critical section at the last engaged thread, especially on recut joints.
Proprietary Steel
Grant Prideco incorporates specially designed proprietary steel for
both the drill pipe tube and the tool joint. Tube and billets are
produced by Grant Prideco mills in Austria and China or obtained
from qualified suppliers, and thoroughly inspected upon receipt to
verify that all material requirements are met. By closely matching
the chemistries of the tube and tool joint materials, Grant Prideco
ensures good weld compatibility and weld strength. Stringent
cleanliness requirements for both materials enhance fracture
toughness. The increased hardenability of the materials consistently produces more uniform mechanical properties throughout
the entire cross-section, commanding adequate strength in the
weld zone and the critical sections of the connection. The result is
a more reliable product. For both API drill pipe and high-performance, severe-environment products, Grant Prideco engineers
materials that increase product performance and integrity.

DRILL PIPE
Tube Processing
Grant Prideco drill pipe is manufactured with state-of-the-art
production equipment. Tube ends are forged on modern Ajax
upsetters featuring programmable heating systems, which
optimize forging efficiency. The computer-controlled pipe handling
system operates cleanly and quietly to transfer tubes quickly and
without damage. Grant Prideco’s modern austenitizing and
tempering furnaces provide a controlled quench-and-temper heat
treatment process for tubes. Tensile and impact properties are then
verified through rigorous testing.
Tube ends are forged on a modern Ajax upsetter.
Tool Joint Processing
Grant Prideco’s computer-controlled, automated forge line
efficiently produces tool joints while reducing risk to employees.
Forged tool joints are precision contoured on modern machining
centers, then batch heat-treated by a controlled atmosphere
quench-and-temper process. API or Grant Prideco proprietary
rotary-shouldered connections are threaded onto the tool joint
using Computer Numerically Controlled (CNC) machine tools.

DRILL PIPE
Welding
A friction or inertia weld process joins tubes and tool joints. Both
processes are highly reliable and cost-effective, and produce
consistent and uniform weld zone properties. In terms of weld
quality, reliability, strength or metallurgical effects, both processes
produce a high-integrity, solid-state weld connection between the
tool joint and the drill pipe tube. The principles of both welding
processes are based on the rotation of one surface against another
at a relatively high speed and under heavy pressure. The friction
between the tool joint surface and the tube surface causes the
contact to heat up below the melting temperature at which they
are forged together, producing the weld.
Grant Prideco’s latest MTI400VX weld line system is fully automated and features a computerized process and data system.
Robotic handling and laser control position systems provide
efficient operation and assure precise alignment between the tool
joint and tube. Subsequently, the weld’s heat-affected zone (HAZ)
receives the patented Tuff-Weld® process.
Tuff-Weld is a post-weld quenched and tempered heat treatment
of the heat-affected zone. The weld zone is heated by induction
to the specified austenitizing temperature, which is followed by
quenching from precisely positioned fluid nozzles. To ensure that
complete tempering is obtained, an area wider than the HAZ is
reheated to the proper tempering temperature by the induction
coil. A full 100% of welds that undergo the Tuff-Weld process are
subjected to hardness testing. The benefits of the Tuff-Weld
process are shown to the right by comparing the two weld zone
photomicrographs.
www.GrantPrideco.com
This photomicrograph depicts a typical normalized and tempered weld zone. The
weld line is clearly evident by the contrasting microstructures of the tool joint
and the tube upset. The microstructure of the higher carbon tool joint contains
predominantly ferrite and pearlite, while the upset is often pearlite and has
lower transitional constituents.
This photomicrograph depicts the typical microstructure of a Tuff-Weld® weld
zone. The similar microstructures of the tool joint and the tube upset make the
weld line difficult to detect. Both display tempered martensitic microstructures.
The result is yield strengths and Charpy impact values superior to those of
normalized microstructures. The Tuff-Weld process consistently produces
stronger, tougher and more uniform weld zone properties. This combination of
strength and toughness enhances fatigue resistance, making the Tuff-Weld
process the most desired post-weld heat treatment in the industry. More than
50% of the drill pipe in the world is produced using the Tuff-Weld process.

Automatic customized inline lathes simultaneously remove the
internal and external ram’s horns. Programmable sanding units
provide a surface finish that is free of stress risers. State-of-the-art
electromagnetic and ultrasonic inspections ensure that weld
inclusions and defects are not present.
Completed drill pipe assemblies undergo an intense inspection
process including a magnetic particle end area inspection, a
full-length Truscope® analysis, high-speed full-body ultrasonic and
electromagnetic inspection for longitudinal and transverse defects
and minimum wall thickness verification.
The MTI400VX weld line system is fully automated and features a computerized
process, robotic control and laser positioning system.
Induction heating and pressurized fluid quench are used in the patented
Tuff-Weld® post-weld heat-treating process. The resulting quenched and
tempered microstructure maximizes weld area properties.

Traceability
Drill pipe assemblies are produced by welding pin and box tool
joints to an upset and heat-treated drill pipe tube. Material and
process traceability are maintained for each of the three components. Mill material certifications for tool joints are confirmed by
incoming testing and each tool joint blank is given a unique heat
code. This code is traceable through the manufacturing process.
A Grant Prideco number is similarly used to provide traceability for
the drill pipe tube. The number is die-stamped for permanent
identification.

DRILL PIPE
Operational Advantages of 5-7/8 inch XR™ Drill Pipe
t)ZESBVMJD1FSGPSNBODF 5-7/8 inch drill pipe provides
enhanced hydraulic performance compared to 5-1/2 inch drill
pipe for ERD and ultra-deep well applications.
t4USFBNMJOFE$POöHVSBUJPO 5-7/8 inch drill pipe utilizes
a 7 inch OD TurboTorque ™ or XT® tool joint, allowing it to be
used to drill inside 9-5/8 inch casing and 8-1/2 inch open-hole
sections. Overshot fishing capability in an 8-1/2 inch hole is
maintained.
t-PHJTUJDT XR eliminates the need for 6-5/8 inch drill pipe,
which is difficult to handle and can sacrifice rig space and
setback capacity because it cannot be used to drill 8-1/2 inch
hole sections.
t3JH.PEJöDBUJPOT 5-7/8 inch drill pipe minimizes rig

F
or more than 25 years, Grant Prideco has been the leader in
the development of rotary-shouldered connections. A
long-standing workhorse of the industry, the HI-TORQUE®
(HT™) connection provides approximately 40% more torque than
comparable API connections.
With an improved thread form and a flatter taper, Grant Prideco’s
second generation eXtreme® Torque (XT®) connection meets the
needs of deep, extended reach and HTHP wells, providing even
more torque, a reduced profile and improved hydraulics. eXtreme
Torque (XT®) connections often allow the use of a larger pipe size
for a given hole size while maintaining fishability.
The eXtreme® Torque Metal Seal (XT-M™) connection is the
industry’s first pressure-rated, gas tight rotary-shouldered
connection. eXtreme® Torque XT-F™ and XT-MF™ offer XT and
XT-M performance with a special fatigue-resistant thread form
for the most severe drilling applications.
Released in 2002, the Grant Prideco Double Shoulder® (GPDS™)
connection provides nearly the torque of the HI-TORQUE connection
with the convenience of interchangeability with the comparable
API connection.
Grant Prideco’s third generation TurboTorque™ (TT™) connection
was introduced in 2006. TurboTorque features a double start thread
form, reduced connection profile and multiple design configurations to meet specific drilling requirements. The results are
optimized torque capacity and hydraulics, improved clearance and
fishability, extended life and reduced risk of failure.
Grant Prideco’s latest development is the gas-tight, pressurerated TurboTorque-M™ (TT-M™), featuring all of the benefits of
TurboTorque connections, with the added advantage of an
advanced metal-to-metal seal.

TurboTorque™ connections are the industry’s first rotaryshouldered connections to offer a double-start thread form. Dual
threads, 180 degrees apart, reduce the number of turns from stab
to makeup by 50%, saving significant rig time. The resulting
increase in thread lead angle provides an increased torque capacity
of 12%.

Stronger Tool Joints
Standard drill pipe tool joints are made of steel with Specified
Minimum Yield Strength (SMYS) of 120,000
000 psi (120 ksi SMYS).
Historically, efforts to increase the
tool joint yield strength have resulted
in reduced fracture toughness and
increased susceptibility to fatigue
crack propagation. TurboTorque
connections are engineered specifically for use with 130 ksi SMYS tool
joints, meeting the increased fracture
toughness required by API and
proprietary manufacturing standards
such as NS-1™, DS-1™ and NORSOK. In
addition, the TurboTorque thread
form and tool joint geometry have
been engineered to provide industryleading fatigue performance. The result is a rotary-shouldered
connection with increased torque capacity, reduced connection
profile, greater fishability and increased hydraulic performance.

Minimum torque is the least amount of MUT acceptable to ensure
that the connection will function properly. Minimum MUT is
normally only considered in cases when the recommended MUT
may exceed capacity of the rig equipment, such as large diameter,
high-strength drill strings or landing strings.
Recommended MUT is used for normal drilling operations. In most
situations, it provides enough torque to prevent downhole makeup
while minimizing connection stress.

TurboTorque connections are the first in the industry to provide a
Turbo-MUT. Also known as “torque-on-demand”, Turbo-MUT
provides an additional 8% of torque capacity for those unusual
drilling situations when additional torque is required. Most of the
testing and design validation for the TurboTorque family were
conducted on connections made up to the Turbo-MUT value.
Extensive testing allows the Turbo-MUT to be used confidently
without having to consult Grant Prideco.

ROTARY-SHOULDERED CONNECTIONS
Optimized Connection Taper
Taper is the controlling factor in the final configuration of a
rotary-shouldered connection. The TurboTorque taper is engineered
to ensure a balance between the pin and box, maximizing
connection stiffness and fatigue resistance. The taper is designed
to deliver maximum tradeoff between tensile strength, torque
capacity and connection profile. The result is a balanced pin and
box, reduced connection profile, connection stiffness and fatigue
resistance, greater fishability, increased hydraulic performance and
optimum balance between all performance parameters.
Optimized Hydraulic Performance
The refinement of the TurboTorque design and 130 ksi SMYS tool
joints mean the tool joint ID can be increased for diminished
pressure loss through the drill string. In comparison to Grant
Prideco’s XT® connection, tool joint ID can often be increased
1/8 of an inch or more. For a given hole size, TurboTorque’s slim
outside diameter often permits the use of a larger pipe size, which
significantly increases hydraulic performance. More hydraulic
horsepower at the bit saves operational cost and enables drilling
of deeper wells.

High–Performance Thread Form
TurboTorque’s thread height is optimized for each of the four design
configurations. The thread form incorporates a unique dual-root
radius, larger than the root radii of API and even XT® connections,
significantly reducing the connection peak stress.
Save Time, Cut Costs
A TurboTorque connection requires the same running procedures
as the XT connection. However, TurboTorque’s double-start thread,
faster taper and deeper stabbing greatly reduces the turns to
makeup. The resulting time saved has a marked effect on rig
economics. Compared to competitive premium rotary-shouldered
connections, TurboTorque connections often pay for themselves on
the first well, then continue to provide operational savings.

Connection
Grant Prideco’s latest rotary-shouldered connection is the result of
an ongoing two year comprehensive design, test and qualification
effort. The TurboTorque-M™ connection incorporates a radial,
metal-to-metal, internal pressure seal, providing all of the benefits
of the industry’s highest performing TurboTorque™ connection with
the added security of a gas-tight pressure sealing capability.
The internal metal seal is generated by radial interference, reducing
the effects of tensile load. Capable of resisting high-pressure liquids
and gas, the seal integrity is not affected by multiple trips.
All sizes of the TurboTorque-M connections are pressure rated at
20,000 psi internal and 10,000 psi external. ISO13679 testing
methodologies for casing and tubing were modified to validate
the connection’s pressure capability under harsh, aggressive,
dynamic loads.
TurboTorque-M drill strings can be used for drill stem testing
operations, high-pressure workover and completion operations,
and underbalanced drilling operations. The TurboTorque-M drill
string eliminates the need for a separate work string, which
ultimately saves time, money, rig space and deck load.

ROTARY-SHOULDERED CONNECTIONS
In addition to providing a 20,000 psi internal and 10,000 psi
external pressure rating, TurboTorque-M™ connections provide
increased mechanical and hydraulic performance compared to
eXtreme® Torque-M™ (XT-M™) connections, while also providing
fatigue performance greater than standard API connections. In
comparison with XT-M, TurboTorque-M provides a 1/4 inch larger
ID for increased hydraulics, 8% additional working torque capacity
and 5,000 ft/lbs of additional rated internal working pressure
(see table).
TurboTorque-M connections are not interchangeable with any
other rotary-shouldered connection, including TurboTorque™
connections.

Rotary-Shouldered Connection
The patented eXtreme® Torque (XT®) connection addresses the
requirements of many extreme drilling applications, including
extended reach drilling (ERD), horizontal drilling, deepwater, high
temperature high pressure (HTHP) and ultra-deep wells.
'MVTI*%
High-Performance Design
The eXtreme Torque connection is a patented, high-performance,
rotary-shouldered connection available in sizes from 2-3/8 inch
through 6-5/8 inch drill pipe. The eXtreme Torque connection
incorporates a second generation double-shouldered design. A
secondary internal torque shoulder on the nose of the pin offers an
additional friction surface and mechanical stop. The primary
external shoulder still serves as the connection’s sealing surface.
The eXtreme Torque connection design has an extended pin base,
pin nose and box counterbore. These sections are carefully
engineered to provide additional elastic deformation during
makeup, ensuring that the contact forces are properly proportioned
between the two shoulder surfaces.

Slim Profile
The XT® connection’s increased torsional strength allows for the
use of a streamlined tool joint that is sized for the pipe’s torsional
strength. XT connections can be configured with a smaller OD and
larger ID compared to standard API connections without sacrificing
torsional capacity. Often, XT connections permit the use of a larger
diameter drill pipe, providing improved hydraulic efficiency, better
hole cleaning and greater buckling strength for horizontal and
extended reach applications without sacrificing torsional strength
or fishability.
User Friendly
XT connections utilize the same running procedures as standard
API connections. The connection spins up freely until shouldered,
then is bucked up to the make-up torque. XT connections have a
more shallow taper, requiring a more shallow stab and slightly
more turns to makeup.
True Flush Inside Diameter
There is no gap or change in the inside diameter from the box to
the pin, creating a smoother flow with less turbulence. This feature
also eliminates the recess found in standard connections where
cement and solids can be trapped.
Rugged Durability
The robust XT connection design incorporates more steel in the
critical areas of the connection resulting in less refacing and fewer
recuts. In addition, because of the increased torsional capacity, the
XT connection greatly extends the life of the joint by tolerating
more OD wear.
Field Repairable
The XT connection can be refaced in an inspection yard or at the rig
site with a portable refacing tool. This flexibility can save time and
expenses by eliminating transportation and handling costs.

The Grant Prideco Double Shoulder™ (GPDS™) connection is a
high-performance, rotary-shouldered connection available for
2-3/8 inch through 6-5/8 inch drill pipe. GPDS connections offer
a versatile alternative to standard API connections where higher
torsional strength is required and are interchangeable with API
connections.

Increased Torsional Capacity
The double-shouldered design of GPDS provides increased torsional
capacity when compared with similar sizes of API connections.
A secondary internal shoulder on the nose of the pin offers an
additional friction surface and mechanical stop. The primary
external shoulder still serves as the connection’s sealing surface.

The GPDS double-shouldered design provides a true flush inside

is downgraded to Class 2 when the OD wears below 6-5/16 inches.
At this diameter, the tool joint is less than 80% as strong as

A New Paradigm in Fatigue Resistance
The DC connection features a unique fatigue
resistant thread form that incorporates a generous
dual thread root radius of 0.060 inch and 0.065
inch. The larger dual-root radius significantly
reduces peak stresses in the thread root and
extends connection fatigue life. The DC connection
pins also include a stress relief feature. Laboratory
test results indicate that the DC58 connection
provides a near full order of magnitude increase in
fatigue performance, at least nine times improved,
compared to API 6-5/8 inch Regular connection.

Improved Make-Up Efficiency
Compared to API Regular connections, the DC™ connection stabs
deeper and makes up with fewer turns. DC™58 connections have
three threads per inch and a steeper three-inch-per-foot taper.
Three revolutions are required to make up the DC58 connection,
compared to six revolutions with a 6-5/8 inch API Regular
connection. DC58 field trials verified improved make-up
efficiency and exceptional post-field trial inspection results.
Workable Make-Up Torque
For larger sizes, the normally high makeup torque of doubleshouldered connections often tests the limits of rig equipment.
DC connections are designed to have make-up torques similar
to the requirements of the API counterpart connection.

IntelliServ® Network Compatible
In order to complete a telemetry network from the bit to the
surface, DC™ double-shouldered drill collars provide an ideal
location for the IntelliServ induction coil placement, with each coil
installed in a protective groove in the secondary torque shoulder.
Minimal Recut Loss
The steeper taper of the DC connection reduces loss from recutting
the connections. Compared to the API 6-5/8 inch Regular connection, the DC58 connection saves just over one inch of material after
each pin recut, and just over 1/2 inch after each box recut.

The SST® and SRT® connections are proprietary connections that
provide increased durability and fatigue resistance compared to
a standard API connection.
The SST connection involves a modification to the pin thread
only; the mating box thread remains standard. Completely
interchangeable with the standard API connections, the SST
connection requires no crossovers or special rig handling
procedures. The SST pin incorporates two primary features. First,
the thread form has an enlarged root radius grooved into the
slab flank. Second, the pin thread body is machined on a slightly
flatter taper than that of the box, effectively behaving like a
variable pitch thread.
The SRT connection involves a modification to the box thread
only; the mating pin thread remains standard. Completely
interchangeable with the standard API connections, the SRT
connection requires no crossovers or special rig handling
procedures. The thread form has an enlarged root radius
grooved into the slab flank.

The patented benchmark provides a reference for dressing the
tool joint’s make-up shoulders. As shown in the adjacent figures,
a 1/8 inch wide step is machined onto the pin base adjacent to the
torque shoulder. Similarly, a 1/8 inch wide step is machined onto
the box counterbore adjacent to the box make-up shoulder. Unlike
the API “tangent bar,” this step provides a reference that is visible
from any position around the connection’s circumference.
The amount of remaining material available for dressing can be
easily determined with a pocket scale. The benchmarks are
machined by the CNC machine tool during the threading process.
This feature results in an accurate placement of the reference
surface.

By placing a refacing benchmark on the external bevel
of the connection, the Xmark™ benchmark allows a
simple determination to be made as to how much
space is remaining to reface the connection prior to
recutting. Available on many new connections
furnished by Grant Prideco, Xmark is the clear solution
to refacing limit uncertainty, and the only practical
method of applying benchmarks to connections
having stress relief grooves, such as drill collars and
heavyweight drill pipe.
Refacing benchmarks show the position of the original
shoulder so the inspector can estimate the amount of
refacing a connection has undergone and determine if
excessive refacing has occurred. An advantage of Grant
Prideco’s proprietary Xmark benchmark is that it
reveals not only the extent of refacing, but also how
perpendicular the refaced seal is to the pipe axis.

Xmark’s user-friendly design eliminates both the measurement and
the math. Because Xmark is visually detectable throughout the full
circumference of the connection, even without removal of the
thread protector, it serves as an excellent indicator for determining
the Xmark benchmark and reveals axial misalignment of the seal,
as well as original shoulder position.

Care and handling procedures for specific Grant Prideco connections are available on our website at www.GrantPrideco.com. The
following procedures outline recommended practices for all Grant
Prideco drill pipe.
1. Check to ensure the counter-balance on the top drive is
working properly and provides a minimum amount of weight
applied to the connection during make-up operations. If the
top drive counter-balance is not working or is adjusted
incorrectly, too much weight will be applied to the connection during make-up and may cause connection damage. To
make adjustments to the top drive counter-balance system,
contact the top drive manufacturer for proper counterbalance adjustment procedures.
2-38
2. Because some sizes of the TurboTorque™, TurboTorque-M™,
XT® and XT-M™ connections have slower tapers than
HI-TORQUE®, GPDS™ or standard API connections, increased
effort regarding pin to box alignment during stabbing
operations is required.
3. Visually inspect pipe and tool joints for damage. If thread
protectors are damaged, remove and visually inspect
connections.
4. If pipe is picked up with handling plugs, check the plugs
for damage before making them up in the drill pipe box
connections. Keep protectors on the handling plugs when
they are lowered down the V door, and until they are screwed
into the box connections.
5. Leave the pin protectors on the pipe as it is pulled up the
V door and when the pipe is lowered into the mouse hole.
Only remove after it is pulled out of the mouse hole.
ROTARY-SHOULDERED CONNECTIONS
6. Break in the top drive saver sub by making it up and breaking
it out to the recommended MUT three times in the rotary
table before it is made up in the top drive. Use a short saver
sub (5-1/2 inches shoulder to shoulder). This will position the
pipe handler torque wrench two inches below the box
shoulder, so it will not crush the counterbore of the box
connection.
7. Stab in the top joint near the rig floor so you can verify that
the pin is centered in the box.
8. Check the top drive torque and iron roughneck torque with
the rig tongs and a recently calibrated load cell to make sure
the correct torque is being applied to the connection. Check
break-out torque to make sure it is not more than make-up
torque.
www.GrantPrideco.com
9. Grant Prideco requires the use of a stabbing guide when
stabbing any TurboTorque-M™ or XT-M™ connection, and
recommends its use for other connections as well. Use of a
stabbing guide: (1) ensures proper pin to box alignment and
reduces stabbing damage to the box seal face, (2) increases
safety by reducing opportunities for finger pinch points when
handling the connection and (3) may actually increase trip
times by reducing time spent by the rig crew when aligning
pin to box connections during tripping operations. Stabbing
guides are available in many types (plastic and stainless
steel) and sizes as shown in the pictures below. The use of a
stabbing guide is NOT required, nor recommended by Grant
Prideco when breaking out connections.
2-39
ROTARY-SHOULDERED CONNECTIONS
11. Proper alignment, along with slow initial makeup of the
starting threads, is critical. Caution is required in making
up the first five or six threads before spinning it up. If the
connection is made up with misalignment and fast spin
up, minor thread damage may occur within the starting
threads. Should this happen, it can be removed with a soft
grinding wheel or a file. This will not be detrimental to the
connection.
12. When pipe is laid down, ensure thread protectors are
installed.
10. Ensure the use of contaminant-free thread compound and
proper doping procedures. Standard thread compounds
generally used with rotary-shouldered connections such as
zinc-based, copper-based, Teflon®-based and other metal
and metal-free thread compounds are compatible with Grant
Prideco connections. Based on in-house testing and field
experience, Grant Prideco has seen more consistent friction
properties for copper-based thread compounds.

ardbanding has been used in the oil and gas industry for
decades. Through years of research and testing, Grant
Prideco has developed some of the industry’s top solutions.
Several hardbanding options are available to meet your drilling
challenges.
Platinum® HB Hardband
Two years of continuous research, development and testing have
resulted in Platinum HB, the industry’s first engineered hardband
solution. Introduced to the market in 2006, Platinum HB delivers
best-in-class tool joint protection in casing, superior resistance to
spalling and cracking, industry-best casing protection and easy
reapplication over itself, with the convenience of a cost-effective
single-source supplier.
SmoothX™ Hardband
A patented hardband of submerged spherical tungsten carbide
granules in a mild steel matrix, SmoothX provides a smooth surface
with little or no exposed carbide.

Platinum® HB
Engineered specifically for drill string hardbanding applications,
Platinum® HB provides minimum casing wear while maintaining
excellent tool joint protection. Today’s severe wear environments of
extended reach, horizontal, deepwater and abrasive hard rock are
easily handled by Platinum HB, making it the ideal choice of both
oil companies and pipe owners for a complete range of drilling
applications. Platinum HB’s near-nanoscale microconstituents offer
a new paradigm of both high strength and high toughness.
Platinum HB provides unsurpassed wear characteristics while
maintaining the impact resistance and toughness necessary to
resist spalling and flaking downhole.
Superior Resistance to Cracking
Through a patent-pending application process, Platinum HB has
been meticulously engineered to contract and expand at the same
rate as the tool joint steel to virtually eliminate cracking during
application and in the field. Other hardbands have traditionally
reduced their strength and hardness to achieve a crack-free
application, consequently sacrificing tool joint protection. Matching
the Coefficient of Thermal Expansion (CTE) of the hardband
material and base tool joint steel enables higher strength and
hardness without detrimental cracking tendencies. Platinum HB’s
high strength and high toughness provide a
wear-resistant hardband with superior
resistance to cracking and spalling. Dye
penetrant testing of applied hardband
materials proves the superior crack resistance of Platinum HB relative to competitive
hardbands (see photos at right).
Best Casing Wear
The near-nanoscale microconstituents of Platinum HB deliver the
industry’s absolute best casing protection. Casing wear tests
conducted at Grant Prideco’s Technology Center show a 37%
reduction in casing wear over the nearest “casing-friendly”
competitor (see graph on next page). Grant Prideco is the only
hardband manufacturer to purchase, install and operate its own
casing wear test machine (see photo above). Throughout the
Platinum HB development program, hundreds of samples were
tested including most competitive casing-friendly hardbands.

Best Tool Joint Wear
Platinum HB not only minimizes casing wear, it provides significantly better tool joint protection than any other casing-friendly
hardband product on the market. This fact has been proven in
comparative tests against the leading hardband solutions currently
available in the industry. The results show a 55% improvement in
radial tool joint wear of casing compared to the second best
solution (see graph below left). With Platinum HB, you get
maximum tool joint protection with no compromise in casing wear
performance, a feat never before achieved by any other hardband.

When considering the long-term cost of drill pipe ownership,
re-application of the hardband is an important consideration. Many
of the unique properties that result in Platinum HB’s superior field
performance also contribute to its ease of re-application. The
“matched” CTE, strength, toughness and virtual elimination of
cracking of Platinum HB permit this hardband to be economically

SmoothX™ Hardbanding
SmoothX™ hardbanding was developed to minimize tool joint
wear. Five bands of the SmoothX hardbanding are applied around a
tool joint, covering approximately 3-1/2 to 4 inches of length. Three
“fingers” of SmoothX hardbanding are applied to the elevator
shoulders to prevent wear and undercutting adjacent to the last
band of hardbanding in open-hole environments. Without these
fingers, erosion of the elevator shoulder could occur, shortening the
life of the tool joint.
Machined groove
Spherical carbide granules
in a mild steel matrix
SmoothX hardbanding is applied in a machined groove on the
tool joint by dropping a measured quantity of spherical, sintered,
30-14 mesh tungsten carbide granules into a molten puddle
formed by welding wire. The granules sink into the molten weld
metal and leave a smooth surface that has little or no exposed
tungsten carbide. The resulting matrix has an increasing density of
tungsten carbide from the surface to the bottom of the deposit.

Radius leading edge
SmoothEdge® Tool Joints
Grant Prideco’s SmoothEdge® tool joints provide a sacrificial wear
pad for the installation of tool joint hardbanding. SmoothEdge is
available for both pin and box tool joint hardbanding applications,
and is width and height adjustable to allow for customer-specific
hardbanding applications. Use of SmoothEdge tool joints and
casing-friendly hardbanding extends the life of the tool joint,
reduces torque and drag operating loads and significantly reduces
casing wear.
Reduced Risk to Downhole Pressure-Sensitive
Components
Often, the leading edge of proud hardbanding applications can be
sharp or jagged, increasing wear or damage to various downhole
components. Grant Prideco’s SmoothEdge tool joint provides a
base material with a radius as the leading edge to the hardbanding
material. The radius reduces wear and tear to items such as seals
within rotating heads and other items whose pressure integrity
are critical, especially within pressure-critical operations such as
underbalanced drilling (UBD) and managed pressure drilling (MPD).

Improved Hardbanding Integrity
Initial Application – Proud hardbanding applications ideally
maintain higher weld bead heights than other applications. The
significant amount of bead deposit required to achieve these levels
often makes the initial application of casing-friendly hardbanding
susceptible to flaking and spalling. Grant Prideco’s SmoothEdge
tool joint provides an expendable wear pad allowing a more
controlled weld bead deposit while maintaining proud application
heights desired to protect the tool joint from wear.

HARDBANDING
Re-application – Re-application of casing-friendly hardbands are
also susceptible to flaking and spalling, largely because they are
designed to weld to a crack-free, base steel metal. However, most
casing-friendly hardbanding re-applications are made over the
existing hardbanding, promoting the probability of hardband
cracking, spalling and loss of material integrity. Grant Prideco’s
SmoothEdge® tool joints provide an elevated sacrificial wear pad
such that the initial hardbanding material can wear down to the
tool joint material itself. This feature allows a re-application to be
made again on the tool joint’s crack-free, base steel material.

rant Prideco offers three types of Heavyweight Drill Pipe
(HWDP). Designed to provide a gradual transition between
drill pipe and drill collars, HWDP improves the fatigue
resistance of the drill string.
Standard HWDP is suited for most applications including vertical,
extended reach and horizontal wells.
Grant Prideco’s Tri-Spiral™ HWDP is suited for applications requiring
additional hole-cleaning and buckling resistance.
Spiral-Wate® HWDP reduces differential sticking, minimizes wear
and improves circulation in especially tough drilling environments.

HEAVYWEIGHT DRILL PIPE
Standard HWDP
Standard Heavyweight Drill Pipe (HWDP), was developed to provide
a gradual transition from heavy drill collars to relatively lightweight
drill pipe. This intermediate weight pipe has a wall thickness of
approximately one inch, and helps prevent stress concentration at
the top of drill collars. HWDP also allows drilling at higher RPMs,
reducing torque and differential pressure sticking.
24”
18°
B
Elevator Upset
Diameter
HWDP is well-suited for directional drilling. Because it bends easily,
it simplifies directional control and minimizes connection fatigue
problems common to high-angle or horizontal drilling.
For extended reach and horizontal wells, especially in wells where
the total vertical depth to total measured depth ratio is low, high
strength heavyweight drill pipe is often used high in the hole to
apply weight on the bit.
Various combinations of HWDP, drill collars and standard drill string
components can be created to meet the challenges of severe
drilling conditions.

HEAVYWEIGHT DRILL PIPE
Tri-Spiral™ HWDP
Grant Prideco developed Tri-Spiral™ Heavyweight Drill Pipe for
extended reach and horizontal drilling applications requiring
greater buckling resistance and hole cleaning than is available with
standard HWDP. The severe bending stresses and hole/wall contact
are reduced by three spiral upsets that are equally spaced between
tool joints. The upset design helps reduce buckling and differential
sticking, as well as torque and drag. Spiraling the upsets also helps
move the cuttings off the low side of the hole for better hole
cleaning.

HEAVYWEIGHT DRILL PIPE
Spiral-Wate® HWDP
Spiral-Wate® drill pipe, spiraled heavy-wall drill pipe, is designed to
handle maximum stress to save time and reduce drilling costs,
especially in tough drilling environments.
Intermediate drill string members are constantly subjected to some
of the most severe tasks in drilling today. The critical transition
zone between stiff, heavy drill collars (under compression) and
the light, more flexible drill pipe (in tension) is critical to the
performance of the drill string.
Spiral-Wate drill pipe’s unique patented spiral design reduces
differential sticking problems, minimizes wear and improves
circulation. Precision tool joint alignment cuts down on excessive
tool joint wear for longer service life and reduced fatigue.

HEAVYWEIGHT DRILL PIPE
Features and Options
Extra-Long Tool Joints
Grant Prideco heavyweight drill pipe is manufactured by welding
extra-long tool joints to heavy-wall tubes. The extra-long tool joint
increases tong space, and allows for several connection recuts to
maximize your investment.
Cold Rolling
Heavyweight drill pipe undergoes repeated severe tensile and
compressive stresses during the drilling operation. As compared to
regular drill pipe, HWDP is much stiffer, focusing cyclic stresses on
the thread roots and potentially resulting in connection failure. To
help alleviate this problem, the thread roots on every piece of
heavyweight drill pipe are cold-rolled by Grant Prideco. Cold rolling
imparts an initial state of compressive stress that minimizes crack
initiation thereby increasing fatigue resistance.
The cold-rolling process consists of compressing metal
fibers by means of a roller to increase fatigue resistance.
5-8
Phosphate Coating
All heavyweight drill pipe connections are given a hot phosphate
coating to provide resistance to galling and corrosion.
Hardbanding
Grant Prideco has several hardbanding materials available to apply
to heavyweight drill pipe including Platinum® HB and SmoothX™,
as well as third-party materials. Hardbanding can be applied in
several configurations to meet specific needs.
Proprietary Rotary-Shouldered Connections
In addition to the API and public domain connections listed in the
previous tables, Grant Prideco can provide heavyweight drill pipe
with proprietary stress relief thread forms or double-shouldered
connections to enhance performance (see Rotary-Shouldered
Connections section).
HEAVYWEIGHT DRILL PIPE
HWDP Grades
Standard Heavyweight Drill Pipe
Grant Prideco standard heavyweight pipe is manufactured from
AISI 1340 material and heavyweight tool joints are manufactured
from AISI 4142H-4145H modified drill collar material.
eXtreme® Drilling XD®-90 Sour Service Grade
eXtreme® XD®-90 HWDP is a proprietary product offered by Grant
Prideco for service in H2S environments. Available in both standard
and spiral designs, XD-90 heavyweight drill pipe provides higher
strength and a tempered martensite microstructure for enhanced
resistance to crack initiation and crack propagation. XD-90 HWDP
incorporates a proprietary chemistry and a rigidly controlled
quench-and-temper heat treatment process. The eXtreme XD-90 is
resistant to sulfide stress cracking and its high fracture toughness
is ideal for the most demanding drilling conditions, including
applications with high bending loads and corrosive environments.

5-9
HEAVYWEIGHT DRILL PIPE
eXtreme® HW™-95 and HW™-120 Heavyweight Drill Pipe
HWTM-95 and HWTM-120 high-strength heavyweight drill pipe are
proprietary grades offered by Grant Prideco for target applications
requiring the use of HWDP high in the hole where elevated tensile
and torsional loading is expected. Both HW-95 and HW-120 provide
high yield strength – 95 ksi and 120 ksi minimum, respectively,
a 73% and 218% increase in yield strength over standard
heavyweight products – resulting in superior tensile and torsional
strength properties. These pipe configurations provide tensile and
torsional capacities equal to or greater than nearly all types of
standard API drill pipes tubes. As a result of the increased strength,
HW-95 and HW-120 are a perfect fit for applications such as short
radius, horizontal and extended reach drilling projects where use of
HWDP above the kick-off point is required for applying bit weight
and additional buckling stability.

rant Prideco Drill Collars are integral heavy-wall joints that
are manufactured from a solid bar of modified alloy steel.
The solid bars are quenched and tempered to obtain the
required mechanical properties, then trepanned, drifted and
threaded. Drill collars are furnished as slick or spiraled in 30 or
31 foot lengths.
Without Spiral
Spiral prevents
differential sticking
Slick drill collars are supplied with the mill as-rolled surface finish.
Spiraled drill collars have grooves machined in the outside surface.
The spiral grooves promote even flow of drilling fluid around the
collar diameter, equalizing pressure and reducing the occurrence
of differential sticking.

Edition and a unit stress of 62,500 psi in the box or pin, whichever is weaker. Torque values are rounded to the nearest 100 ft-lb.
(2) Normal torque range is calculated value plus 10%. Higher torque values may be used under extreme conditions.

NOTES (cont'd):
(3) In each connection size and type group torque values apply to all connection types in the group, when used with the same drill collar OD and bore, i.e. 2-3/8 API IF, API NC26
and 2-7/8 Slim Hole connections, used with 3-1/2 x 1-1/4 drill collars, all have the same minimum make-up torque of 4600 ft-lbs and the box is the weaker member.
(4) Stress-relief features are disregarded for make up torque calculation.
(5) H-90 connection make-up torque is based on 56,200 psi stress and other factors, as listed in note 7.
(6) 2-7/8 PAC make-up torque is based on 87,500 psi stress and other factors, as listed in note 7.
(7) Torque figures in bold indicate that the weaker member for the corresponding outside diameter and bore is the box. For all other torque values, the weaker member is the pin.

Compared to other drill stem accessories, Grant Prideco requires a
more robust material for top drive saver sub applications. The subs
are manufactured from steel that meets ASTM specifications A370,
E23 and E30, and is pre-formed and drilled before heat-treating.
Subs are then batch heat-treated to obtain a minimum yield
strength of 120,000 psi, minimum tensile strength of 140,000 psi,
minimum Charpy impact strength of 40 ft-lbs at 70ºF and a
hardness of 293-341 BHN. The required mechanical properties
are at mid-wall of the pin. A thru-wall Brinell hardness is taken
at 1/4 inch below OD, mid wall and 1/4 inch from the ID. All
heat-treated blanks are sandblasted and wet-magnetic-particle
inspected prior to final machining and threading.

Top Drive Pump-In Subs
Rotary Kellys
Specifically designed for use with top
drives, Grant Prideco’s pump-in sub
provides additional space (up to 3-1/2 feet)
between the bottom of the top drive
stabbing bell and the pump-in assembly.
The added space allows for easier
installation of your pump-in line assembly
and for safer operations when moving of
the drill string is required, such as landing
a casing liner. For an integral lift sub, the
top drive pump-in sub incorporates either
a 1502 or 2202 Weco thread as its upper
connection for the most common pump-in
connections.
Grant Prideco offers square and
hexagonal kellys, available up to
46 feet long. The kellys are made
from 4145-modified alloy bars that
are quenched and tempered full
length. A hardness range of 285 to
341 BHN and a minimum impact
value of 40 ft-lbs are maintained
one inch below the surface at
room temperature. All ends
and center drive sections are
machined. Grant Prideco kellys are
precision-trepanned to provide
true bores. They are drifted to API
specifications and all connections
are machined. Grant Prideco kellys
are stamped with the API
monogram, when applicable.

Care and Maintenance
Initial Make-up
A generous and thorough application of high-quality thread dope
(minimum 40-60% by weight metallic zinc) will help minimize
galling.
New connections should be “walked in” with chain tongs. Always
use the recommended make-up torque for the connection type.
Verify that torque measuring equipment is properly calibrated.
After initial makeup, break out the connection, then clean and
inspect the threads, faces and shoulders. Repair any minor damage,
re-lubricate and re-make the connection.
Repeat breakout and makeup a third time before going into the
hole. Monitor break-out torque; it should be the same or less than
the make-up torque. High break-out torque is an indication of
damage, and the connection should be inspected.
Although the current industry BSR calculation for single-shoulder
rotary-shouldered connection types may still be applicable for
double-shoulder connections (HT™, XT®, GPDS™), the appropriate
target ranges are yet to be defined due to limited industry
experience and testing of available types/sizes. Testing performed
to date indicates that current target BSR of 2.5 does not apply to
tested double-shouldered connections.
Just as target BSR for single shoulder rotary-shouldered connections has taken many years of industry experience to define, the
same may be true for these double-shoulder offerings. Additionally,
target BSRs for double-shouldered connections may likely vary
between connection types (i.e. GPDS vs. XT). Current industry
target BSR ranges should not be used as an indicator of doubleshoulder acceptance/rejection.
Maintenance
Use thread protectors on both connection ends when handling drill
collars. Rotate connection breaks on each trip. Clean and inspect
the individual connections. Qualified personnel should periodically
conduct a magnetic particle/black light inspection. Collars that are
left idle or put in storage should be cleaned, inspected, repaired
and rust-proofed, as necessary, before installing thread protectors.
Bending Strength Ratios
Sizes less than six inches should have a Bending Strength Ratio
(BSR) of 2.25:1 to 2.75:1. Conditions that require high RPM and
small collars compared to the hole size, use 2.25:1 to 3.00:1. If the
RPM is kept low and the collars are closer to the hole size, use 2.25:1
to 3.20:1. In corrosive environments, use 2.50:1 to 3.00:1.
