Carbon Steel Pipe

Description

Carbon steel pipes are widely used in many fields because of their excellent physical and chemical properties. We have advanced technology and sufficient inventory to supply seamless steel pipes and welded steel pipes of various specifications.

Product Description

Carbon steel pipes are made of steel ingots or solid round steel perforated into capillary tubes, which are then hot rolled, cold rolled or cold drawn.
Carbon steel seamless steel pipes are divided into two types: hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes due to different manufacturing processes. Cold drawn (rolled) pipes are divided into two types: round steel pipes and special-shaped pipes.
Hot-rolled carbon 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.
In addition to general steel pipes, low and medium pressure boiler pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes and other steel pipes, carbon cold-rolled (rolled) steel pipes also include carbon thin-walled steel pipes. -Wall steel pipes, alloy thin-walled steel pipes, rust-proof thin-walled steel pipes, special-shaped steel pipes.
Carbon steel pipes can be divided into seamless steel pipes and welded steel pipes.
