ASTM WK39012

    Work Item: ASTM WK39012 - Revision of A249 / A249M - 10a Standard Specification for Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes

    (What is a Work Item?)

    Active Standard: A249 / A249M - 14

    Developed by Subcommittee: A01.10 | Committee A01 | Contact Staff Manager



    1. Rationale

    Refine the weld bead tolerance exceptions for small OD (less than 0.500) tubes. Accurate measurements become increasingly problematic and we find that small OD A249 product (less than 0.500) is not used with the expectations commonly required of larger heat exchanger sizes.
