Seamless carbon steel pipe ASTM A192 specification parameter table

Mar 19, 2024

ASTM A192 Carbon Steel Tube Specification covers seamless carbon steel boiler tubes for high pressure applications.
ASTM A192 seamless steel pipes are used as minimum wall thickness, seamless carbon steel boiler and superheater tubes for high pressure. CSC STEEL provides ASTM A192 steel pipes in hot-rolled and cold-drawn delivery conditions, usually used in high-pressure boilers (working pressure does not exceed 9.8Mpa , the working temperature is between 450℃-650℃) heating surface pipes, headers, economizers, superheaters, and reheaters.
