Hot-rolled seamless steel pipes are further divided into general steel pipes, stainless steel pipes, high-pressure boiler steel pipes, medium-pressure boiler steel pipes, low-pressure boiler steel pipes, petroleum cracking pipes, alloy steel pipes,geological steel pipes and other steel pipes. In addition to alloy steel pipes, general steel pipes, petroleum cracking pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, stainless steel pipes, and other steel pipes,cold-rolled seamless steel pipes also include stainless thin-walled steel pipes, carbon thin-walled steel pipes, and alloy thin-walled steel pipes.Wall steel pipes and special-shaped steel pipes.
The outer diameter of hot-rolled seamless pipes is generally greater than 32mm,and the wall thickness is between 2.5-75mm, while the outer diameter of cold-rolled seamless pipes can reach 6mm and the wall thickness can reach 0.25mm, and the outer diameter of thin-walled pipes can reach 5mm and wall thickness. less than 0.25mm.Seamless steel pipes are rolled from carbon structural steel, low-alloy structural steel, and alloy structural steel, so their output is the largest. Seamless steel pipes are mainly used as pipes or structural parts for conveying fluids.
application
