Rotary impact drill pipes are mainly used in rock drilling and crushing, anchoring drilling, geothermal air conditioning holes, water well drilling, etc. The two ends of the pipe body are internally thickened, tempered after friction welding, quenched and tempered after rough machining of drill pipe joints, phosphating or nitriding after finishing. It effectively eliminates the failure probability of gluing, broken buckles, outer diameter swelling and cracking, is more wear-resistant and easy to disassemble.
