HD series product: Designed for large coring drilling, HD drilling rod 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.
