ASTM A192/A192M specifications covers minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high pressure service. The tubing 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 ASTM A192/A192M.

Manufacture: tubes shall be made by the seamless process and shall be either hot-finished or cold-finished, as specified.
Heat Treatment: hot-finished tubes need not be heat treated. Cold finished tubes shall be heat treated after the final cold-finishing at a temperature of 1200°F [650°C] or higher.
Inspection & Test: chemistry composition analysis, tensile test, flattening test, flaring test, hardness test, NDT, surface inspection and dimension check.

Length: 5800mm; 6000mm; 6096mm; 7315mm; 11800mm; and so on.
Max length: 30000mm, U bending can be offered, also see the fin tubes.
