Product Detail


Product Overview：

Seamless steel pipes for boilers can be divided into medium and low pressure boiler pipes and high-pressure boiler pipes, which belong to a type of seamless steel pipe. There are strict requirements for the steel grades used in the manufacturing of steel pipes. Seamless steel pipes for boilers are often subjected to high temperature and high pressure conditions, and the pipes 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. Seamless steel pipes for boilers are mainly used to manufacture superheater pipes, reheater pipes, air ducts, main steam pipes, etc. for medium and low pressure and high pressure boilers.
