ASTM A192 Boiler Seamless Steel Pipe JIS G3456 DIN 17175 Round

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 to manufacture steel pipe. According to the use of temperature is divided into two kinds of general boiler tube and high-pressure boiler tube.

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

① The general boiler tube temperature is below 350℃, domestic pipe is mainly made of No. 10, no. 20 carbon steel hot rolled pipe or cold drawn pipe.

(2) High-pressure boiler pipes are often used in high temperature and high pressure conditions, and the pipes are used in high temperature flue gas and water vapor

Oxidation and corrosion can occur when used. The steel pipe is required to have high durable strength, high oxidation corrosion resistance and good microstructure stability
