Product Description
|
ASTM A178/A178M is a specification for electric-resistance-welded carbon steel and carbon manganese steel boiler and superheater tubes. This specification covers tubes with various wall thicknesses and diameters, primarily used in high-pressure applications such as boilers and superheaters in power plants.
These tubes are manufactured through a welding process called electric resistance welding, where the edges of the steel strip are heated and fused together using electrical resistance. The resulting tubes have excellent mechanical properties, including high tensile strength and good toughness.
ASTM A178/A178M specifies the chemical composition and mechanical properties of the steel used for manufacturing these tubes. The tubes are required to be properly heat treated to achieve the desired properties.
These tubes are widely utilized in power generation plants, industrial boilers, and other high-temperature and high-pressure applications. They are designed to withstand elevated temperatures and provide reliable performance in demanding environments.
Overall, ASTM A178/A178M sets the standard for the quality and performance of electric-resistance-welded carbon steel and carbon manganese steel tubes used in boiler and superheater applications.
