6m Regular 2 3/8" API Thread Foundation Drilling Alloy Steel DTH Drill Pipe for DTH Hammer

DTH drill pipes 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, accuracy.

1. High quality pipe

Hardness and wear resistance combined alloy steel, supplied by national top level special steel manufacturer.

2. 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.

3. Stability and durability thread
Premium alloy steel made joints, strictly controlled heat treatment process and standard API thread processing technology; we pay high attention to all these ignored details to ensure a long service life, stability and thread durability.

Product Description:
According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice versa. Usually we are offering Rotary and DTH drill pipes, Reverse Circulation Drill Pipes, HDD drill pipes with diameter 50mm, 60mm, 76mm, 89mm, 95mm, 102mm, 114mm, 127mm, 140mm, 159mm and some are produced of friction welding and integral forging technology;
