Process requirements for manufacturing high pressure boiler tubes with large diameter seamless steel

The high-pressure boiler tube is a kind of boiler tube. The high-pressure boiler tube is mainly used for manufacturing the superheater tube, the reheater tube, the air guiding tube and the main steam tube of the high pressure and ultra high pressure boiler. Belonging seamless steel tubes categories. Oxidation and corrosion can occur. Steel pipes are required to have high durability, high oxidation resistance, and good structural stability. The manufacturing method is the same as that of seamless pipes, but there are strict requirements for the steel used in the manufacture of steel pipes. High-pressure boiler tubes are often used under high temperature and high pressure conditions, and the tubes are under the action of high temperature flue gas and water vapor.
