   DTH drill pipe is mainly used for rock crushing,anchoring drilling,geothermal air conditioning hole,water well drilling,etc. Materials are purchased from well-know large enterprise of domestic. The ends of pipe are IU processed,then temered after friction welding.Drill pipe joints are quenched and tempered after rough machining,and surface nitriding treament after finishing ,that makes the joints more wear-resistant and easy to disassemble without thread gluing,breaking and joint expansion and cracking.Precision imported CNC lathes and customized forming cutters are used for thread processing. All threads are equipped with thread gauges that meet international standards. All process can extend service life of drill pipe and make the quality stable and reliable.
     We can produce DTH drill pipes of different materials, lengths,diameters,and wall thicknesses, and we can also customize drill pipes according to the materials,lengths,wall thicknesses,and threads required by customers.
