Traditionally the threads and the joint between the tube and the end-pieces are vulnerable. To combat the problem we've friction-welded the joints for maximum strength and heat-treated the end-pieces for optimum durability.
Drill pipe is generally described by tube OD, nominal weight, pipe grade, type tool joint, thread connection and classification.
We do special heat-treating the threads ensures not only a long service life, but also simplifies joining and breaking.
standard material for drill pipe is R780,but other material S135,G105 are available.
----The other specification drill pipes are available upon request.
----Kinds of Thread API REG,IF or BECO or produced as customer required.
----All of the drill pipes are friction thread.
----More large size of pipe from 127mm to 500mm drill pipe are available.
