Seamless steel pipe for high-pressure boiler
High pressure boiler seamless tube is a type of boiler tube, belonging to the category of seamless steel tube
Product details
High pressure boiler seamless tube is a type of boiler tube, belonging to the category of seamless steel tube. The manufacturing method is the same as seamless pipes, but there are strict requirements for the steel grade used in the manufacture of steel pipes. High pressure boiler tubes are often subjected to high temperature and high pressure conditions during use, and the tubes will undergo oxidation and corrosion under the action of high-temperature flue gas and water vapor. Steel pipes are required to have high durability, high resistance to oxidation and corrosion, and good structural stability. High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts, main steam tubes, etc. for high-pressure and ultra high pressure boilers.
Seamless tubes for high-pressure boilers are used as heating surface tubes for low and medium pressure boilers (with a working pressure generally not exceeding 5.88Mpa and a working temperature below 450 ℃); Used for heating surface tubes, economizers, superheaters, reheaters, petrochemical industry tubes, etc. of high-pressure boilers (working pressure generally above 9.8Mpa, working temperature between 450 ℃ and 650 ℃).
The development of high-pressure boilers towards high-performance parameters and extended service life requires increasingly higher steel grades, and there is a need for domestic new material research and pipe manufacturing to lag behind.
