increased space for connection rework.
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.

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

eXtremeª DRILLING 90 GRADE SOUR SERVICE ™
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.
