  • Astm A213 T22 Seamless Alloy Pipe - China

    price: contact company for price

    ASTM A213 T22 Seamless Ferritic and Austenitic Alloy-Steel

    Boiler, Superheater, Heat-Exchanger Tubes.

    Grades containing the letter H in their designation have

    requirements different from those of similar grades not

    containing the letter H.

    These different requirements provide higher creep-rupture

    strength than normally achievable in similar grades without

    these different requirements. ASTM A213 T22 tubes shall be

    made by the seamless process and shall be either hot

    finished or cold finished, as specified. Grade TP347HFG

    shall be cold finished. Heat treatment shall be done

    separately and in addition to heating for hot forming. The

    ferritic alloy and ferritic stainless steels shall be

    reheated. On the other hand, austenitic stainless steel

    tubes shall be furnished in the heat-treated condition.

    Alternatively, immediately after hot forming, while the

    temperature of the tubes is not less than the minimum

    solution temperature, tubes may be individually quenched in

    water or rapidly cooled by other means. Tension test,

    hardness test, flattening test, and flaring test shall be

    done to each tube. Also, each tube shall be subjected to the

    nondestructive electric test or hydrostatic test.

    ASTM A209 Through A213

    Other standard specifications include the categories of A209

    seamless carbon-molybdenum alloy-steel boiler and

    superheater tubes; A210 seamless medium-carbon steel boiler

    and superheater tubes and A213 seamless ferritic and

    austenitic steel boiler, superheater and heat-exchanger


    Piping wall thicknesses range from 1/2 inch to 5 inches.

    A213 grades also have the letter H or M assigned, which

    changes the composition and specifications for that series.
