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.

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.
