The manufacturing method of boiler pipe
Nov 29, 2018

Boiler pipe is a kind of seamless pipe. The manufacturing method is the same as that of seamless pipe, but there are strict requirements on the steel types used in the manufacturing of steel pipe. According to the use of temperature is divided into general boiler tube and high pressure boiler tube two.

The mechanical property of boiler tube is an important index to guarantee the final service property (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In the steel pipe standard, according to different requirements for use, the provisions of the tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness index, as well as user requirements of high and low temperature performance.

(1) general boiler tube temperature under 350 ℃, the domestic pipe mainly use 10, 20 carbon steel hot rolled or cold drawn tube manufacture.

(2) high pressure boiler tube is often used in high temperature and high pressure conditions, pipe in high temperature smoke and steam for

When used, oxidation and corrosion occur. Steel tubes are required to have high endurance strength, high corrosion resistance and good microstructure stability.
