Product Description
Cold-rolled seamless pipes are cold-drawn or cold-rolled precision seamless pipes used for mechanical structures and hydraulic equipment with high dimensional accuracy and good surface finish. In addition to general Steel Pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, Stainless Steel Pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (pulled) seamless pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Stainless thin-walled steel pipe, special-shaped steel pipe. The outer diameter of the hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can reach 6mm and the wall thickness can reach 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.

application
Seamless Steel Tubes are used in large quantities as pipes for transporting fluids, such as pipes for
transporting petroleum, natural gas, gas, water and certain solid materials. It is an economical section steel
that is widely used in the manufacture of structural and mechanical parts, such as oil drill pipes, automotive
drive shafts, bicycle frames, and steel scaffolding used in construction.
