Heavy Weight Drill Pipe (HWDP) from China Suppliers & Factory - API Spec 7-1 Compliant
Features
Quenching and tempering heat treatment for optimized toughness and wear resistance.
100% FLUT inspection on pipe bodies (longitudinal, transverse, ultrasonic thickness), and 100% UT/MPI on tool joints, upset ends, and weld zones.
Optional upgrades: make-up/breakout torque tests, cold-rolled threads, spiral grooves on center wear pads.
Performance enhancing surface options include internal plastic coating (IPC) and hardbanding for extended tool life.
With extensive field applications in both onshore and offshore drilling, TAKELO HWDP has repeatedly demonstrated lower failure rates and extended run life, making it a trusted choice for operators seeking durability and reduced non-productive time (NPT).

Frequently Asked Questions
What quality inspections are performed on the Heavy Weight Drill Pipe?
We conduct 100% FLUT inspection on pipe bodies (including longitudinal, transverse, and ultrasonic thickness), as well as 100% UT/MPI on tool joints, upset ends, and weld zones.
Are there any optional upgrades available for the HWDP?
Yes, optional upgrades include make-up/breakout torque tests, cold-rolled threads, and spiral grooves on center wear pads to enhance performance.
What surface coating options do you provide?
We offer several internal plastic coating (IPC) options, including TK34, TK34P, TC2000, and DPC2000, to extend the tool's run life.
Which hardbanding options can be applied to the drill pipes?
Our hardbanding options include Arnco 100XT, Arnco 300XT, and other industry-standard applications to improve durability and wear resistance.
Why should operators choose TAKELO HWDP?
With extensive onshore and offshore field applications, TAKELO HWDP has repeatedly demonstrated lower failure rates and extended run life. This makes it a trusted choice for operators looking to maximize durability and reduce non-productive time (NPT).
