Product Description
We can supply seamless steel pipes and welded steel pipes in various materials and specifications.
Carbon steel pipes can be divided into seamless steel tubes and welded steel tubes.
Carbon steel welded steel pipe are divided into straight seam welded pipes and spiral welded tubes according to the form of welds. Classification by production method: process classification – submerged arc welded steel pipe, arc welded steel pipe, electric resistance welded steel pipe, (high frequency, low frequency) gas welded steel pipe, furnace welded steel pipe.
Carbon steel seamless steel pipe are divided into two types: hot-rolled (extruded) seamless steel tube and cold-drawn (rolled) seamless pipes due to their different manufacturing processes. Cold drawn (rolled) tubes are divided into two types: round steel tubes and special-shaped tubes.
Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel tubes, 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 tubes, high pressure boiler steel tube, alloy steel tubes, stainless steel tubes, petroleum cracking pipes, and other steel pipes, carbon cold-rolled (dial) steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Rust thin-walled steel pipes, special-shaped steel pipes.
