Product Description:

114mm R780 gread Steel Double Wall Drill Pipe 6000mm Length

The double wall drill pipe is a full hole drilling tool, and the hole wall clearance is small, so there is no space condition for collapse of broken rock blocks. The double wall drill pipe has a certain supporting effect on the hole wall. The continuity of the drilling process of drill pipe avoids the damage to the drilling caused by the pressure excitation and suction caused by frequent lifting and lowering of drilling tools.
