Seamless Steel Tube Manufacturer

Seamless steel pipes, made from a solid piece of metal with no joints on the surface. According to the production method, seamless pipes are classified into hot-rolled, cold-rolled, cold drawn, extruded, and jacking pipes, among others. By cross-sectional shape, they are divided into round and special-shaped pipes, with special shapes including square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and winged pipes. The maximum diameter reaches 650mm, while the minimum diameter is 0.3mm. Depending on their application, they are available in thick-walled and thin-walled versions. Seamless steel pipes are primarily used for oil and gas geological drilling pipes, cracking pipes for petrochemical use, boiler pipes, bearing pipes, and high-precision structural steel pipes for automotive, tractor, and aviation use.
