Product Description
We can provide users with the supporting drill pipe of various specifications, thread forms and steel grades for the drilling machine.
1.
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. Therefore,
the occurrence of thread galling and shackle torque can be reduced,
accordingly.
2.
Since the clamping space is expanded, the trenchless drilling machine
positioning and clamping become easier. More importantly, the extended
joint can be repaired for the occurrence of worn thread. The drill rod
is meticulously designed with special performance for trenchless
construction, to reduce the production cost..
3. 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.
