Geological NTW HTW BTW Drill Rods Oil Quench Hardened Drill Rod For
Boart Longyear Wireline Core Barrel Drilling
Introduction
This geological drill pipe is mainly composed from the small pitch screw thread between rod body and joint. And it features high cost-effective, good wear resistant and long service life. We provide six kinds of geological drill pipes in different diameters for customers around the globe.
Superior performance
Drill rods and casing are quality-crafted in standard sizes using
superior alloy steel, with each end of the rodsheat-treated for
greater wear resistance. Drill rods and casing also provides a
tight mechanical seal. Developed to meet or surpass the performance
of any similar product, the superiority of drill rods has been
confirmed in actual surface and underground drilling field test
operations.
Reasonableprocess
Our products feature an anti-rust coating and are ready for
drilling. Each thread is lubricated and protected using recyclable
cardboard packaging and steel caps. In order to reduce
environmental impact, packaging for drill rods and casing is
entirely recyclable and does not contain any plastic.
