What are the seamless steel tubes for high-pressure boilers

Seamless steel tubes for high-pressure boilers are mainly used in tubes, headers, economizers, superheaters, heat exchangers and other parts of high-pressure boilers. The working pressure of seamless steel tubes for high-pressure boilers is generally above 9.8MPa and the working temperature is between 450℃ and 650℃. The executive standard is GB / T5310.

The main grades of seamless steel tubes for high pressure boilers are 20G, 20MnG, 15MoG, 15CrMoG, 12Cr2MoG, 12Cr1MoV, etc. For the seamless steel tubes used for high pressure boilers, their service environment and related properties are also different.

The production process of seamless steel tubes for high pressure boilers is more strict than that of ordinary steel tube. In the process of using seamless steel tubes for high pressure boilers, oxidation and corrosion will occur under the action of high temperature flue gas and steam. Therefore, the requirements for the durability and anti-oxidation corrosion performance of seamless steel tubes for high-pressure boilers are higher, and it has requirements for good structural stability.
