Premium Drillpipe
for Optimal Performance
DRILCO offers a full line of
premium drillpipe available
in a variety of sizes with API and
non-standard wall thickness to
deliver optimal torque, weight,
and durability. Our manufacturing
capability ranges from 27⁄8-in to
75⁄8-in diameter drill pipe in E,
X, G, S or SS GRADES in both
Range 2 and Range 3 lengths.
Special sizes and proprietary
grades are available on an
individual order basis. Our
technical representatives can
help you select the best
features to ensure maximum
BHA performance.

Premium drillpipe
Fatigue in the transition area between the tool joint and the drillpipe is
the most common cause of washouts and failures. Therefore, DRILCO uses
specialized forging equipment, proprietary tooling, and manufacturing
techniques to develop drillpipes with extended upset design and gradual
taper, producing a uniform mechanical property throughout the material.
The smooth transition between components results in a clean steel and
enhanced hardenability. In addition, our proprietary tube chemistries are
matched to our quench and temper heat treatment processes to achieve
excellent impact values, high fatigue resistance, and extended product life.
Optional Features
■■
Extended upset double shouldered premium connections
■■
Premium hardbanding
■■
Internal plastic coating
■■
Factory make-up and break-out
Extended upset design maximizes drillpipe durability
by reducing stress resistance
Drillstring durability is maximized by designing pipes that are resistant to
fatigue, which is concentrated in areas with sudden changes in geometry.
This is the upset area adjacent to the tool joint weld, which serves as the
transition from the drillpipe’s cross-sectional part to the tool joint’s thick
cross-sectional part. To increase stress resistance, the upset transition zone
between the drillpipe’s body and the tool joint needs to be as smooth and
gradual as possible.
DRILCO selects steel with stringent cleanliness requirements to ensure
high fractured toughness that translates into higher safety margins. Using
proprietary equipment for the upset areas, we can specify an extended
internal upset with a shallow run-out angle that blends seamlessly into the
drillpipe’s ID. These qualifications improve pipe performance and ensure its
durability in this stress-prone region. To further reduce fatigue, we grind
both the ID and OD of the assembled pipe adjacent to the weld line.
Tool joint forgings are required to meet or exceed API standards. Prior to
assembly, each tool joint is inspected to guarantee dimensional properties and
test to ensure they provide proper mechanical integrity. Our tool joints are
usually supplied 2-in longer than standard API lengths to deliver additional
re-cut capability and longer service life. Tool joints with longer lengths can
also be supplied by special request.

Double-shouldered connections improve torque
and hydraulic performance
DRILCO offers drillpipe with standard API threaded connections for all
available sizes. In addition, we offer DRILCO DS compatible double-shouldered
connections, which use a standard API thread form with a secondary
internal shoulder. The connection allows you to increase ID or reduce OD,
which significantly improves hydraulic and torque performance over
conventional API connections. The DRILCO DS connections are compatible
with standard API connection thread forms as well as other standard
double shouldered connections.
Typical double-shouldered connections provide 30% to 40% greater torque capacity than
standard API connections.

Hardbanding minimizes deterioration during drilling
and casing rotation
Hardbanding material can be welded to the tool joint’s circumference to
protect it from deterioration during drilling. Some hardbanding types also
offer protection for the casing when rotating inside the casing. Whether
the application is for standard tungsten carbide or casing friendly using our
proprietary DRILCO DEFENDER series hardbanding products, we have the
materials available to meet your most stringent requirements. Please be
sure to specify your requirements when ordering or discuss your options
with our DRILCO representatives.
Internal plastic coating prevents corrosion
and maximizes durability
The internal plastic coating is applied to the inside of the drillpipe to
prevent corrosion and extend pipe service life by reducing friction
coefficient and improving flow rate and hydraulics. To provide you
with high-quality coatings and fast turnaround on orders, we partner
with coating service companies that have a proven reputation for
timely deliveries based on scheduled workloads.
