ASTM standard for low and medium pressure carbon steel boiler tubes

Boiler tubes are classified into three primary categories based on material: carbon steel, alloy steel, and stainless steel. To ensure the durability, safety, and performance of boiler tubes under various pressure conditions, boiler tubes need to confirm with ASTM standard. This blog will talk about ASTM standard for low and medium pressure carbon steel boiler tubes.

ASTM Standards for Low and Medium Pressure Carbon Steel Boiler Tubes:

- ASTM A178:

This standard covers electric resistance welded (ERW) carbon steel and carbon-manganese steel tubes for boilers and superheaters. It is applicable to pipes ranging from 1/2 inch to 5 inches in diameter, with wall thicknesses between 0.035 and 0.360 inches. Compliance with mechanical properties, such as tensile strength and elongation, as well as chemical composition, is required.

- ASTM A192:

This standard pertains to seamless carbon steel boiler tubes with diameters between 1/2 inch and 7 inches and wall thicknesses starting from 0.049 inches. It outlines specific mechanical and chemical properties and includes requirements for heat treatment, degassing, and specialized testing methods.

- ASTM A210:

Applicable to seamless carbon steel pipes used for boilers and superheaters, this standard governs pipes with diameters from 1/2 inch to 5 inches and wall thicknesses between 0.035 and 0.500 inches. It places additional emphasis on creep performance at high temperatures, differentiating it from other standards.

- ASTM A213:

This standard focuses on seamless ferritic and austenitic steel tubes for use in high-temperature applications like boilers and heat exchangers. It covers tubes with diameters from 1/8 inch to 5 inches and wall thicknesses from 0.015 inch to 0.500 inch, and specifies processes such as cold working and annealing.

- ASTM A333:

Covering both seamless and welded steel pipes for cryogenic applications, this standard applies to pipes with diameters ranging from 1/8 inch to 24 inches and wall thicknesses from 0.015 to 1.000 inches. The ASTM A333 standard also includes testing protocols for extreme temperature conditions, such as impact and cold bending tests.
