What is high pressure boiler tube

High pressure boiler tube is a kind of boiler steel tube, which belongs to the category of seamless steel tube. The manufacturing method of high pressure boiler tube is the same as that of seamless tube, but there are strict requirements for the steel grades used for manufacturing high pressure boiler tube.

The high pressure boiler tube is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the tubes will be oxidized and corroded. The high pressure boiler tube is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability. High pressure boiler tube is mainly used as superheater tube, reheater tube, air tube, main steam tube, etc. of high pressure and ultra-high pressure boiler.
