Friction welding drill pipeWhat are the principles of the production process?

1,The outer casing body of the drill pipe is cold drawn; the wall thickness of the pipe body is guaranteed to be positive difference and the uniformity of wall thickness.±0.15mm,The joint is42CrMoAMaterial, the joint is treated with vacuum gas nitriding after finishing, which enhances the hardness and wear resistance of the drill pipe joint.

2,Thread processing In order to ensure the accuracy of the drill pipe connection exchange, the joint thread is processed by high-precision CNC lathe and imported forming clamp processing.WEI Lida Prospecting Machinery Co., Ltd.Friction welding drill pipe, have80tons,200tons,320ton friction welding machine3The friction welding between the drill pipe joint and the drill pipe body is carried out by using continuous inertia friction welding technology, and the welding parameters are monitored by computer to ensure the superiority of the drill pipe.

3,Friction welding drill pipeList a fewDomestic drill pipe examples: drill pipe is widely used in mine construction, geothermal well construction, water well construction.
