Astm A355 Grade P22 Chrome Molybdenum Alloy Steel Seamless Pipe 16mo3 Alloy Steel Pipe Astm A335 P22 for Oil and Gas Production Line Seamless steel pipe is a steel pipe made from a single piece of metal without joints on its surface. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and pipe jacking. According to the cross-sectional shape, seamless steel pipes can be divided into two types: round and special-shaped. Shaped tubes come in many complex shapes, such as square, oval, triangle, hexagon, melon seed tube, star tube and finned tube. The maximum diameter is 650mm and the minimum diameter is 0.3mm. Depending on the application, there are thick-walled and thin-walled tubes. Seamless steel pipes are mainly used in petroleum geological drill pipes, cracked pipes in the petrochemical industry, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.
