    Product Information:
    Friction welding drill pipe is in accordance with  API  or  5DP specification.The steel grades are E75, X95, G105 and S135,went through partly or overall heat treatment.

    OEM is accepted

    The smooth tube and the original steel tube material are made into drill rods after several processing steps. First, through the processing of the steel tube thickening process, the outer surface of the smooth tube is bent inward, and the wall of the steel tube is thickened. In the next step, the threads are processed and plated with copper that increases strength. Then carry out non-destructive quality control inspection, followed by welding of steel pipe joints. Then, the pipe body will undergo welding heat treatment and welding final treatment to eliminate welding residual pressure. Before painting and packaging the finished drill pipe, some other tests should be carried out on the finished steel pipe, including hardness test, pressure test and non-destructive test.
    What is the role of drill pipe?
    The drill rod is a rod member connected in the drilling tool to transmit power. It is a device that transports drilling mud to the drill bit and raises, lowers or rotates the bottom hole together with the drill bit. The drill pipe can withstand huge internal and external pressure, twisting, bending and vibration.
    Drill pipe technology introduction
    The advanced drill pipe friction butt welding production line can adjust the welding parameters to a good position to ensure the quality of the welding strip; the heat treatment process of internal and external cooling at the same time, the mechanical properties are even and stable. Equipped with automatic length measurement and weighing, automatic spray mark recording to ensure product traceability. Advanced drill pipe thickening and heat treatment production line. Use 1250T pier thick machine to ensure the thickening of the pipe end
    Meet the requirements of API SPEC 5DP standard; adopt CNC tube full-length heating furnace, quenching machine, tempering furnace advanced heat treatment process and temperature control to ensure the mechanical performance of the tube body. The straight hydraulic machine of the pipe body ensures the straightness of the pipe body and the coaxiality of the pipe body.
