ASTM A53 Grade (A or B) Seamless Carbon Steel Pipe Zinc Coated Surface

Seamless carbon steel pipe is a capillary tube made of steel ingots or solid tube blanks through perforation, and then hot rolled, cold rolled or cold drawn. Seamless carbon steel pipes have an important position in my country's steel pipe industry.

Chemical Requirements

The specifications of seamless steel pipes are expressed in millimeters of outer diameter * wall thickness. Seamless steel tubes are divided into two types: hot-rolled and cold-rolled seamless steel tubes.

Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
Cold rolled (dial) seamless steel pipes are divided into 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, as well as carbon thin-walled steel pipes, alloy thin-walled steel pipes, Stainless thin-walled steel pipes, special-shaped steel pipes. The outer diameter of hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The diameter of cold-rolled seamless pipe can be up to 6mm and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up to 5mm and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.
