USES:

Used in the manufacture of boiler water wall, economizer, reheater, superheater and steam pipe.

Boiler tube is a kind of seamless tube. The manufacturing method is the same as seamless pipe, but there are strict requirements on the type of steel used in the manufacture 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 ensure the final service performance (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In the steel pipe standard, according to the different use requirements, stipulate 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) The general boiler tube temperature is below 350℃, the domestic pipe is mainly made of 10, 20 carbon junction steel hot rolled pipe or cold drawn pipe.

② High pressure boiler tube is often used in high temperature and high pressure conditions, the tube in high temperature flue gas and water vapor under the action, will occur oxidation and corrosion. Steel tubes are required to have high durable strength, high oxidation corrosion resistance, and good tissue stability.
