ASTM A192 is a standard for seamless carbon steel boiler and superheater tubes with minimum wall thickness for high-pressure applications. The dimensions and thicknesses of the pipes normally supplied in accordance with this specification are 1/2 "to 7" outside diameter (12.7 to 177.8 mm) and minimum wall thickness is 0.085 to 1.000 "(2.2 to 25.4 mm). Tubes of other sizes may be supplied provided they meet all other requirements in this specification.
ASTM A192 Seamless Carbon Steel Boiler Tubes specification covers seamless carbon steel boiler tubes for high-pressure service. Recommended pipe size will be developed by us upon receipt of your inquiry. A print or sketch of the part to be produced should be included. Grade, chemical analysis and surface condition are carefully considered, and production processes are tailored to achieve the best tubing for the end use.
The ASTM A192 Seamless Carbon Steel Boiler Tubes shall be made by the seamless process and shall be either hot-finished or cold-finished. Hot-finished tubes need not be heat treated. Cold-finished tube shall be heat treated after the final cold-finishing at a temperature of 1200°F [650°C] or higher.
Size:OD: 12.7-177.8mm, WT: 2.2-25.4mm, L:6-3.2m
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.
