The difference between medium and high pressure boiler pipes

　　Depending on the operating temperature, medium pressure or high pressure boiler pipes shall be used. It is generally divided into the following situations:

　　The working temperature of common boiler pipe is lower than 450 ℃. Hot rolling or cold drawing process is mainly adopted for the medium pressure boiler pipeline. High Pressure Seamless Steel Boiler Pipe is usually used under high temperature and high pressure conditions. Under the action of high temperature flue gas and steam, the pipeline will be oxidized and corroded. High pressure boiler tubes with high durability, high oxidation resistance, corrosion resistance and good organizational stability are needed.
