Kev piav qhia:
Boiler tube is a type of seamless tube. The manufacturing method is the same as seamless pipes, but there are strict requirements for the type of steel used in the manufacturing of steel pipes. According to the usage temperature, it is divided into two types: general boiler tubes and high-pressure boiler tubes.
①Generally, boiler tubes are used at temperatures below 350 ℃, while domestically produced tubes are mainly made of hot-rolled or cold drawn carbon steel tubes of grades 10 and 20。
②High pressure boiler tubes are often subjected to high temperature and high pressure conditions during use. Under the action of high-temperature flue gas and water vapor, the tubes will undergo oxidation and corrosion. Steel pipes are required to have high durability, high oxidation and corrosion resistance, and good structural stability.

ASTM A192 / A192M-17 Cov Lus Qhia:
This standard applies to high-pressure boilers (exceeding 350 MPa)The boiler tube is required to be able to withstand high temperature and high pressure conditions Work and have good pressure resistance and strength.
ASTM A210 / A210M-19 Cov Lus Qhia:
This standard applies to the boiler tubes of low and medium pressure boilers (not exceeding 500 MPa), requiring the tubes to have high pressure resistance and heat resistance, and be able to withstand high temperature and high pressure conditions.
ASTM A213 / A213M-19 Cov Lus Qhia:
This standard applies to seamless and welded boiler tubes used in high-temperature environments for boilers and heat exchangers. The tubes are required to withstand high temperature and high pressure conditions, and have high corrosion resistance and heat resistance
