3087 seamless steel pipe is a kind of seamless steel pipe with high precision and high brightness produced by cold drawing or cold rolling process
3087 Classification of seamless steel pipes: seamless steel pipes are divided into hot rolled and cold rolled (drawn) seamless steel pipes.
Hot rolled seamless steel pipes include 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.
In addition to 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, cold rolled (rolled) seamless steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes and special-shaped steel pipes.
