ASTM WK41869

    Work Item: ASTM WK41869 - Revision of B359 / B359M - 12 Standard Specification for Copper and Copper-Alloy Seamless Condenser and Heat Exchanger Tubes With Integral Fins

    (What is a Work Item?)

    Active Standard: B359 / B359M - 12e1

    Developed by Subcommittee: B05.04 | Committee B05 | Contact Staff Manager



    1. Rationale

    There is an alternative process for the formation of enhanced surface tubes that provides significant cold working of the raw material, increasing the collapse strength when tested per ASME Appendix 23. This increase in the yield strength from cold working cannot be included in designs as the standard is currently constructed.
