Mechanical properties for tool joint materials are
tabulated on page 18 of this catalog.
API Specifications
Heavy Weight Drill Pipe is manufactured in compliance with the following API standards, as applicable:
API Specification 7
API Recommended Practice 7G
API Specification Q1
Traceability
Material and process traceability are maintained for each Heavy Weight Drill Pipe component. For the tool joints,
the mill material certifications are confirmed by incoming testing and each tool joint blank is given a numbered
heat code. This code is traceable through the manufacturing process. The heavy weight drill pipe tube is given a
permanent identification number.
Cold Rolling
Drill pipe undergoes repeated, severe tensile stresses during a drilling operation. These cyclic stresses are particularly
focused on the thread roots and can cause pipe failure. Grant Prideco helps alleviate this problem by compressing
(cold rolling) the thread roots on every piece of heavy weight drill pipe. Because the threads are in a compressed state
to begin with, the endurance limit to bending forces is increased, thereby decreasing fatigue.

It also allows you to drill at higher rpms,
reducing torque and differential pressure

HWDP is intended primarily for directional
drilling. Because it bends easily, it simplifies
directional control and minimizes connection

fatigue problems common to high-angle or

pipe failures and increased drill-stem service also make HWDP appropriate for
some straight-hole applications.

™
eXtreme XD -90 Heavy Weight Drill Pipe
™
XDª-90 Heavy Weight Drill Pipe (HWDP) is a proprietary product offered by Grant Prideco for service in H2S
environments. XDª-90 HWDP is available in both Standard and Spiral HWDP.
XDª-90 HWDP provides higher strength and a tempered martensite microstructure for enhanced resistance to
crack initiation and crack propagation compared to conventional HWDP. XDª-90 HWDP incorporates a proprietary chemistry and a rigidly controlled quench and temper heat treatment process. XDª-90 HWDP has a minimum yield strength of 90,000 psi compared to standard welded HWDP with a minimum yield strength of 55,000
psi. With a NACE threshold stress of 85% of yield strength, XD-90ª HWDP is resistant to sulfide stress cracking.
Its high fracture toughness makes XDª-90 HWDP ideal for the most demanding drilling conditions, including
applications with high bending loads and corrosive environments.

HW-95ª high strength heavy weight drill pipe grade is a proprietary
grade offered by Grant Prideco for target applications requiring the
use of HWDP high in the hole where elevated tensile and torsional
loading is expected. HW-95ª HWDP features a high yield strength
(95 ksi minimum), a 73% increase in yield strength over standard
HWDP products, resulting in superior tensile and torsional strength
properties. HW-95ª HWDP was specifically designed such that tensile and torsional capacities are equal to or greater than nearly all
types of standard API drill pipes tubes. As a result of the increased
strength, HW-95ª HWDP is a perfect fit for applications such as
short radius, horizontal, and extended reach drilling (ERD) projects
where use of HWDP above the kick-off point is required for applying
bit weight and additional buckling stability.
