15CrMog high-pressure boiler tube implementation standard (part): GB T5310-2017
15crmog high pressure boiler tubes in stock(Click on the avatar for details).
The high-pressure boiler tube is under high temperature and high pressure conditions when used, and the tube will oxidize and corrode under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high good strength, high soothing reaction corrosion performance, and good structural stability. High-pressure boiler tubes are mainly used to manufacture superheaters, reheaters, water walls, economizers, etc. of supercritical or ultra-supercritical boilers.
It can produce both thick-walled pipes with a wall-diameter ratio of 36% and thin-walled pipes with a wall-diameter ratio of less than 4%.
The use of mature perforation technology, unique cold-processing-technology, advanced moist-slippery-process, stable-stable-reliable heat treatment technology, etc., overcomes the ultra-supercritical environment of high temperature, high pressure and high steam corrosion, shortens the construction period of power stations, and promotes the power industry to reduce costs and improve efficiency.
For domestic and foreign high-level boiler manufacturers, the products have been successfully applied to domestic and foreign power projects.

A high-pressure boiler tube is a type of boiler tube that belongs to the category of seamless steel tubes. The manufacturing method is the same as that of seamless pipes, but there are strict requirements for the steel grades used to manufacture steel pipes. High-pressure boiler tubes are often under high temperature and high pressure conditions when used, and the tubes will oxidize and corrode under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high lasting strength, high oxidation and corrosion resistance, and good structural stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide pipes, main steam pipes, etc. for high-pressure and ultra-high-pressure boilers.
Among them, substitute materials: 20 pots of chromium-molybdenum pot, 12 chromium 1 molybdenum vanadium pot, 15 nickel 1 manganese, molybdenum, niobium copper, 10 chromium, 9 molybdenum, 1 vanadium, niobium nitrogen, etc.
