Seamless Carbon Steel Pipe ASTM A192 Specification Parameter Table

The ASTM A192 specification outlines the requirements for seamless carbon steel boiler tubes designed for high-pressure applications. These pipes are typically used in power plants and industrial boilers where high temperatures and pressures are involved. ASTM A192 seamless steel pipes are characterized by their minimum wall thickness, making them ideal for use in critical components such as boiler tubes, superheater tubes, headers, economizers, and reheaters. CSC STEEL offers ASTM A192 steel pipes in both hot-rolled and cold-drawn conditions, suitable for high-pressure boilers operating at pressures not exceeding 9.8 MPa and temperatures ranging from 450Â°C to 650Â°C.
