Quick Inquiry

ASTM A192 / A192M, ASME SA192 / SA192M is the standard applicable to Seamless carbon steel boiler tubes for High-pressure service.

ASTM A192 / ASME SA192 Standard covers minimum-wall thickness, seamless carbon steel boiler and superheater tubes for high- pressure service.

ASTM A192 / ASME SA192 Tubes sizes and thicknesses usually furnished to this specification are 1⁄2 in. to 7 in. [12.7 to 177.8 mm] outside diameter and 0.085 to 1.000 in. [2.2 to 25.4 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.

ASTM A192 / ASME SA192 Tubes mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] inside diameter or 0.015 in. [0.4 mm] thickness.
