Seamless steel pipe is a kind of hollow section, no joints around the strip of steel. Steel pipe is divided into hot rolled and cold drawn (rolled) two kinds, hot rolled seamless pipe is generally processed on automatic lathe, its outer diameter,wallthickness dimension precision is higher, smooth surface, uniform wall thickness, can be fixed or times thesize of the delivery;The specifications of cold-rolled (dial) seamless steel pipes are expressed in terms of externaldimensions (such as outerdiameter or side length) and wall thickness. The size range is 2-200mm in diameter.

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.
