What is the difference between low and medium pressure boiler tube and boiler tube

The low and medium pressure boiler tube belongs to the boiler tube, and the boiler tube includes the low and medium pressure boiler tube and the high pressure boiler tube.

The working pressure of low and medium pressure boiler tubes is generally not more than 5.88 MPA and the working temperature is below 450℃. It is used to manufacture all kinds of low and medium pressure boilers, superheated steam tubes, boiling water tubes, water wall tubes, superheated steam tubes, large smoke tubes, small smoke tubes and arch brick tubes for locomotive boilers.

The working pressure of high pressure boiler tube is generally above 9.8 MPa and the working temperature is between 450℃ and 650℃. High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts and main steam tubes of high-pressure and ultra-high-pressure boilers.
