ASTM WK35775

    New Specification for End Caps for Polyethylene Pressure pipe in Nominal Pipe Sizes (NPS) 2-inch to 54-inch ( 63mm to 1372mm)

    (What is a Work Item?)

    Developed by Subcommittee: F17.10 | Committee F17 | Contact Staff Manager


    1. Scope

    This specification covers the polyethylene material, the dimensions for flat end-caps, and tori-spherical end caps in NPS 2-in to 54-in polyethylene pipe, and the design equations used for the determination of pressure rating of end caps. The end-caps may be injection or compression molded, or machined from flat plate.


    end cap; flat cap; domed cap; blank; hemispherical, tori-spherical, elliptical;


    Polyethylene pipe has been made for 50-years. There are no dimensional nor pressure rating standards for end-caps. The industry needs standard dimensions and design equations for the pressure rating of end-caps. This new standard will solve that need.

    The title and scope are in draft form and are under development within this ASTM Committee.
