High-pressure boiler tube is a type of boiler tube and belongs to the category of seamless steel tube. The manufacturing method is the same as that of seamless pipes, but there are strict requirements for the type of steel used in manufacturing steel pipes. High-pressure boiler tubes are often exposed to high temperature and high pressure conditions during use. Under the action of high-temperature flue gas and water vapor, the tubes will oxidize and corrode. Steel pipes are required to have high lasting strength, high resistance to oxidation and corrosion, and good structural stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc. for high-pressure and ultra-high-pressure boilers.
Pressure boiler tube specifications: 6mm-1240mm×1mm-200mm
High-pressure boiler tube manufacturing processes: fine drawing, brightening, hot rolling, cold drawing, and thermal expansion.
