The seamless pipe for boiler is a kind of boiler pipe, which belongs to the category of seamless steel pipe. The manufacturing method is the same as that of seamless pipe, but there are strict requirements for the type of steel used for manufacturing steel pipes. Seamless tubes for boilers are often used under high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the tubes will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation and corrosion resistance, and good organizational stability. Seamless pipes for boilers are mainly used to manufacture high-pressure steam pipes and main steam pipes.

Use of seamless pipe for boiler

1. Seamless pipes for general boilers are mainly used to manufacture 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.
2. Seamless tubes for high-pressure boilers are mainly used to manufacture superheater tubes, reheater tubes, air ducts, main steam pipes, etc. of high-pressure and ultra-high-pressure boilers.

Production method of boiler seamless pipe

A kind of seamless pipe for boiler. The manufacturing method is the same as that of seamless pipe, but there are strict requirements for the type of steel used for manufacturing steel pipes. According to the use temperature, it can be divided into general boiler tube and high-pressure boiler tube.
1. The service temperature of seamless tubes for general boilers is below 450 ℃. China mainly uses No. 10 and No. 20 carbon-bonded steel hot-rolled tubes or cold-drawn tubes.
2. Seamless tubes for high-pressure boilers are often used under high temperature and high pressure conditions. The tubes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high endurance strength, high oxidation and corrosion resistance, and good organizational stability.
