The main manufacturers of high-pressure boiler tubes are Tianjin Pipe Group Corporation, Tianjin Seamless Steel Pipe Factory, Baosteel in Shanghai, Pangang, and Hengyang Valin.
High-pressure boiler tubes are a type of boiler tube and belong to the category of seamless steel pipes. The manufacturing method is the same as that of seamless steel pipes, but there are strict requirements for the types of steel used in their production. When in use, high-pressure boiler tubes often operate under high temperature and high pressure conditions. Under the influence of high-temperature flue gas and steam, oxidation and corrosion can occur. Therefore, the steel pipes are required to have high creep strength, high resistance to oxidation and corrosion, as well as good structural stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, lead pipes, and main steam pipes for high-pressure and ultra-high-pressure boilers.
