High-pressure boiler tubes are a kind of seamless steel pipes. Due to the high temperature working environment will have a large amount of water vapor, then the steel pipes will undergo oxidation and corrosion. That make boiler tubes have good corrosion resistance and organizational stability.

GB 5310 high-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc.. The low and medium pressure boiler tube the national standard 3087, and the high pressure boiler tube the national standard 5310. Usually, the hot-rolled tube of high-pressure boiler tube has an exterior range of 22-530mm, and a wall thickness of 20-70mm. The outer diameter of the cold drawn tube is 10-108mm, and the wall thickness ranges from 2--13mm.

The steel grades of high-quality carbon structural steel for high-pressure boiler tubes are 20G, 20MnG, and 25MnG. The steel grades of alloy structural steel are 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB and other materials.
