Feature
1. Precisely friction welded to ensure straightness and concentrically;
2. Special heat treatment process to ensure that the connecting thread has sufficient strength and wear resistance;
3. The body of the drill rod and the joint are welded by a friction welding process, and then the intermediate frequency return is used to remove the welding stress to ensure the welding strength and the straightness of the finished drill rod.
4. Thread part is process nitrogen treatment and upsetted.
We can also supply DTH drill pipe from diameter 76mm to 140mm.
