    Revision of B744 / B744M - 05(2011) Standard Specification for Aluminum Alloy Sheet for Corrugated Aluminum Pipe

    (What is a Work Item?)

    Active Standard: B744 / B744M - 05(2011)

    Developed by Subcommittee: B07.08 | Committee B07 | Contact Staff Manager



    WK46452

    1. Rationale

    1. H34 is required for the riveted pipe because of the higher seam strengths afforded by the material. Since helical pipe design is based on the mechanical properties for the H32 temper, there is no compromise in using the higher values of the H34 temper. 2. Table A12-9 of the AASHTO LRFD Bridge Design Specifications explicitly allows H32 and H34 temper materials for the production of helical pipe. 3. Manufacturers can successfully produce helical pipe with the H34 material.
