Steel pipes made from a single piece of metal without seams on the surface are called seamless steel pipes. According to the production method, seamless pipes are divided into hot rolled pipes, cold rolled pipes, cold drawn pipes, extruded pipes, and top pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. Special-shaped pipes have square, oval, triangle, hexagon, melon seed, star, and finned pipes. The maximum diameter is 650mm and the minimum diameter is 0.3mm. According to different purposes, there are thick-walled pipes and thin-walled pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
