Product Details

PHD series drill rod designed for large coring drilling, PHD wireline coring drill rods features reliability,

firmness and big thread. It is applicable for heavy rope coring.

Pipe Body: Quality alloy steel pipe is adopted and 100% test is conducted for each raw material to ensure uniform concentricity, straightness and heat treatment.

Thread: Bigger and deeper thread (2.5 threads per inch) provides maximum durability. 40% load efficiency provides sufficient strength for well drilling with large diameter.

Thread Surface Hardening: after special process treatment, outer thread surface hardness is up to about 55HRC, which effectively avoids "sticking thread" and reduces abrasion and "stuck" due to engagement of thread.

PHD Drill Rods Overview

* Material : 4130

* Tubing

  • High quality alloy steel tubing

  • Consistent concentricity, straightness and heat treatment

  • All tubing available in DCDMA sizes

* Thread

  • Tapered, course threads (3 threads per inch) provides easy make and break

  • Load efficiency of 30% provides sufficient strength for average applications

* Thru-wall Heat Treatment

  • Provides 140% material strength

  • Heat treated box threads significantly increases thread wear life

* Case Hardening

  • Significant research, development and field testing have resulted in a hardening process that is unequalled.

  • Pin thread crest is hardened to nominal 55 HRC to eliminate damaging ‘adhesion’ wear

  • Eliminates the transfer of wear material back and forth which is what happens between threads of equal hardness, leading to large scalegalling and joint seizing



Note: For making sure the performance of the drill rods, never mix our rods with any another manufacturer’s rods together, also it may cause machinery failures and catastrophic accident.
