The manufacturing process of thick-walled seamless steel pipes can be divided into four basic methods: cold drawing, cold rolling, hot rolling, and hot expansion. The material of the steel pipe is
, and is called ordinary steel pipe, which is between ordinary steel pipe and alloy Steel pipes are called low alloy steel pipes. The materials of steel pipes are M, rM, rM, rM, rM and stainless steel pipes are collectively called alloy steel pipes. According to the purpose, it is divided into structural seamless steel pipes, seamless steel pipes for transportation, seamless steel pipes for boilers, high-pressure seamless steel pipes for boilers, high-pressure seamless steel pipes for fertilizer equipment, seamless steel pipes for geological brick exploration, seamless steel pipes for petroleum brick exploration, and seamless steel pipes for petroleum cracking. Seamless steel pipes for ships, cold-drawn, cold-rolled precision seamless steel pipes, various alloy pipes.

The expression method of seamless steel pipe is outer diameter
*wall thickness. Thick-walled seamless steel pipes are mainly used in mechanical processing, coal mines, hydraulic steel, and other purposes.
