BS3059 Gr.360 Cold drawing High-Pressure Boiler Steel Pipe

BS 3059 II 360 requirements specification for carbon, alloy and austenitic stainless steel tubes with specified elevated temperature properties. Boiler pipe refers to one of the seamless steel pipes. The method of manufacturing boiler tubes is the same as seamless steel pipe, but this pipe has a requirement of steel grades. Depending on the operating temperature, it can be divided into two kinds: general boiler pipes and high-pressure boiler pipes.
A general boiler pipe is able to work below the temperature 450°C. It’s made of hot-finished or cold-rolled carbon steel pipes. While high-pressure boiler tube is used to produce high-pressure or ultrahigh-pressure superheater tube, reheater tube,gas-guide tube, main steam pipe and so on. Our product BS3059-II 360 10 belongs to this boiler tube.
