Oil steel Tube

Carbon steel pipe in the performance of the outstanding performance is high yield strength and stress corrosion resistance, has good weldability, welding cold crack and hot crack are less sensitive.
Carbon steel tubes are divided into hot rolled and cold rolled (drawn) steel tubes.
Hot rolled carbon steel tubes are divided into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes.
Cold rolled (dial) carbon steel pipe generally are divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin wall steel pipe, alloy thin wall steel pipe, stainless steel pipe, special-shaped steel pipe.
