What is a high pressure seamless steel pipe? It is a type of boiler tube and belongs to the category of seamless steel tubes. The manufacturing method is the same as the seamless steel pipe, but there are certain strict requirements for the steel type used for manufacturing the steel pipe. Because high pressure boiler tubes are often used at high temperature and pressure, high pressure boiler tubes are mainly used to make superheater tubes, reheater tubes, steam guide tubes, and main steam tubes for high pressure and ultra high pressure boilers.

The production method of high-pressure seamless steel pipe is divided into general boiler tubes and high-pressure boiler tubes according to the use temperature. High-pressure seamless steel pipes are used at temperatures below 450 ° C. Domestic pipes are mainly manufactured by hot-rolled or cold-drawn tubes of 10 # and 20 # carbon-bonded steel. High pressure seamless steel pipes are often in high temperature and high pressure conditions when used. Under the action of high temperature flue gas and water vapor, the tube will oxidize and corrode. Steel pipes are required to have high durability, high resistance to oxidation and corrosion, and good structural stability.

High-pressure seamless steel pipes are widely used, mainly for manufacturing water-cooled wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes, and arch brick pipes. In addition, superheater tubes, reheater tubes, air ducts, and main steam tubes can be used in power plants that manufacture high-pressure and ultra-high-pressure boilers.
