ASTM A192 high pressure Seamless Boiler tubes,Hot Rolled Steel pipes

ASTM A192 covers minimum-wall-thickness, seamless carbon steel boiler tubes and superheater tubes for high pressure service. The tubing sizes and thicknesses usually furnished to this requirements are 1/2 in. to 7 in. [12.7 to 177.8 mm] outside diameter and 0.085 to 1.00 in. [2.2 to 25.4 mm], inclusive, in minimum wall density. Tubing having other dimensions may be furnished, supplied such tubes adhere to all other requirements of this spec.
