Down The Hole Drill Pipe For Mining
Down the hole drill pipe has a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability. Our DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe. The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.
Standard DTH drill pipe:
Diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm,
Length: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;
Thread: 2 3/8" API REG, 2 7/8" API REG, 3 1/2" API REG, 4 1/2" API REG, 2 3/8 API IF, 3 1/2 API IF
High quality pipe
Hardness and wear resistance combined alloy steel, supplied by national top level special steel manufacturer.(pipe thickness and material can be user's choice).
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.
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 ensures a long service life, stability and thread durability.
We can supply all series of drilling equipment and drilling tools
By using high-quality raw materials, utilizing advanced craft technologies and imposing strict quality inspection, the product range covers:
Down the hole hammer and bits, drill pipes, threaded drilling bits, reverse circulation hammers and bits, shank adapters and coupling sleeves, drilling rig, air compressor and spare parts for drill equipment.
