    Abstract - (Show below) - (Hide below)

    Specifies flanges principally intended for waterworks purposes, with working and test pressures for Classes 14, 16, 21 or 35 at temperatures not exceeding 80 degrees Celsius, that have bolting details compatible with the appropriate table of AS 2129. Dimensions are given for copper alloy plate and integral without neck flanges, ductile cast iron screw-on and integral with neck flanges, grey cast iron integral with neck (for pipe fittings) and integral without neck (for other than pipe fittings) flanges and steel blank, plate and integral without neck flanges for ranges of DN (nominal size) and class. Specifies grades of material and requirements for selection of bolting and assembly of flanged joints.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for circular flanges manufactured from copper alloy, ductile cast iron, grey cast iron, or steel. It covers nominal sizes (see Table 2.1) with pressure ratings for Classes 14, 16, 21 or 35 at temperatures not exceeding 80C. The flanges are for use on pipes, pipe fittings, valves and other equipment that are primarily intended for the conveyance or storage of water or wastewater. NOTE: Guidelines to purchasers on information that should be supplied at the time of enquiry ororder are detailed in Appendix A.
