R780 DTH Drilling Rod Drill Pipe Drilling Tools for Deep Water Well Drilling
DTH Drilling Rod Drill Pipe Drilling Tools play an important role in DTH drilling - regardless of application, rock type, hole depth or drill rig. The key features of a high quality drill pipes are durability, high hardness, stability and accuracy.
l High Quality Pipe
Hardness and wear resistance combined alloy steel, supplied by national top level special steel manufacturer.
(pipe thickness and material can be customized by user's choice).
l No Weak Links
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.
l Stability and Durability Thread
Premium alloy steel made joints, strictly controlled heat treatment process and standard API thread processing technology;
We pay much attention to all these ignored details to ensures a long service life, stability and thread durability.
