Seamless steel pipe: Made by rolling, stretching or extrusion process with a solid solution temperature higher than 770℃, it has high strength and high temperature resistance, a smooth surface, and is suitable for occasions with high requirements on sealing and pressure bearing performance, such as high-pressure pipeline systems.
Seamless steel pipe is mainly used for petroleum geological drilling pipe, petrochemical cracking pipe, boiler furnace pipe,bearing pipe and high-precision structural steel pipe for automobiles, tractors and aviation.
