To maintain the stability of the drilling pipe, this range of boring rod comes with double force-bearing shoulders for the application with high torque and wide angel to decentralize the stress.

The drill rod is meticulously designed with special performance for trenchless construction, to reduce the production cost.ģ. More importantly, the extended joint can be repaired for the occurrence of worn thread. Since the clamping space is expanded, the trenchless drilling machine positioning and clamping become easier.

Therefore, the occurrence of thread galling and shackle torque can be reduced, accordingly.Ģ. Different from copper plating and parkerizing, the joint surface of our drill pipe for friction welding is specially processed to improve the hardness of the thread and the adhesion of the thread grease. We can provide users with the supporting drill pipe of various specifications, thread forms and steel grades for the drilling machine.ġ. 4 1/2'' hdd drill rod with api thread directional drill rods
