1)It is mainly used in rock drilling and breaking, anchor drilling, geothermal air conditioning holes, water well drilling, etc.
2)The pipe body is made of materials produced by well-known domestic large iron and steel enterprises.
3)Both ends of the pipe body are internally thickened, tempered after friction welding, drill pipe joints are subject to quenching and tempering heat treatment after rough machining, and the surface is phosphatized and nitrided after fine machining. Effectively eliminating the probability of failure such as sticking, breaking, and outer diameter cracking, it is more wear-resistant and easy to disassemble.
4)All threads are processed using precision CNC lathes and customized forming cutters. All threads are equipped with thread gauges that comply with international standards, so the quality of the produced drill rods is stable and reliable, and the service life is greatly extended.
