ASTM WK44157

    Revision of A787 / A787M - 09 Standard Specification for Electric-Resistance-Welded Metallic-Coated Carbon Steel Mechanical Tubing

    (What is a Work Item?)

    Active Standard: A787 / A787M - 14

    Developed by Subcommittee: A01.09 | Committee A01 | Contact Staff Manager


    1. Rationale

    #1 - Table 4 and 10 present outside dimensions for round and square/rectangular shapes. The latter has a footnote specifing that measurements are to be taken at least two inches from the end as is the case for other tubing product such as A513 and A500. Table 4 for round product does not. The ballot would reconcile Table 4 to match Table 10 and other approved specifications. #2 - Subcommittee A01.09 and Committee A01 approved a change to another shaped tubing specification, A500,to disallow the seam weld to be located within the corner radius unless specified by the customer.
