The manufacturing process of thick-walled seamless steel pipe production can be divided into four basic methods: cold drawing, cold rolling, hot rolling, and hot expansion. The materials of steel pipes are 10#, 20#, 35#, and 45#, which are called ordinary thick-walled seamless steel pipes. 16Mn is between ordinary steel pipes and alloy steel pipes and is called low-alloy thick-walled seamless steel pipes. The materials of steel pipes are 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, and stainless steel pipes, which are collectively called alloy thick-walled seamless steel pipes.

According to the purpose, it is divided into thick-walled seamless steel pipes for structures; thick-walled seamless steel pipes for transportation; thick-walled seamless steel pipes for boilers; high-pressure thick-walled seamless steel pipes for boilers; high-pressure thick-walled seamless steel pipes for fertilizer equipment; thick-walled seamless steel pipes for geological brick exploration; thick-walled seamless steel pipes for petroleum brick exploration; thick-walled seamless steel pipes for petroleum cracking; thick-walled seamless steel pipes for ships, etc.
