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 treatment after finishing, that makes the joints more wear-resistant and easy to disassemble without thread sticky, breaking 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 extended service life of drill pipe, the quality is stable and reliable.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.
