7/2011 <br /> <br />15060 - 3 <br />The single gasket push-on pipe shall be shipped in standard 18-foot or 20-foot lengths, but <br />not both. The restrained single-gasket push-on joint pipe shall be shipped in standard 18 or <br />20-foot lengths as specified above or fabricated lengths as noted in each order. At least two <br />lengths of each size of single gasket push-on pipe furnished under each order shall be tested <br />with circumferential gauges to insure that the pipe may be cut at any point along its length <br />and have an outside diameter which will be within the manufacturer's standard design <br />dimensions and tolerances for plain pipe. These lengths shall be identified with an easily <br />distinguished, painted marking, longitudinally along the full length of the pipe. <br /> <br />C. FITTINGS <br /> <br /> Fittings Conforming with ANSI/AWWA C110/A21.11-98 (Water & Sewer Use) <br /> <br />Restrained push-on joint fittings shall be cast ductile iron for use with ductile-iron pipe as <br />specified above. Standard mechanical joint, push-on joint and flanged joint fittings shall also <br />be ductile iron for use with ductile-iron pipe as specified above. Cast ductile-iron fittings in <br />the 3-inch through 24-inch size range shall be pressure rated at 350 psi, minimum; (except <br />flange-joint fittings shall be rated at 250 psi, minimum); and in the 30-inch through 48-inch <br />size range shall be pressure rated at 250 psi, minimum. All fittings with mechanical joints, <br />flange joints and push-on joints shall conform to ANSI/AWWA Standard C110/A21.10-98, <br />"Ductile-Iron and Gray-Iron Fittings, 3 In. Through 48 In., for Water and Other Liquids". In <br />addition, fittings with mechanical joints and push-on joints shall conform to ANSI/AWWA <br />Standard C111/A21.11-00, "Rubber-Gasket Joints for Ductile-Iron Pressure Pipe and <br />Fittings". <br /> <br />The weight of fittings, shall be as given in ANSI/AWWA C110/A21.11-98 for ductile-iron <br />fittings. The weight of mechanical joint fittings shall be as established in Tables 3 through <br />12. The weight of flanged joint fittings shall as established in Tables 13 through 20. <br /> <br /> Fittings Conforming with ANSI/AWWA C153/A21.53-00 (Water & Sewer Use) <br /> <br />All fittings shall be cast ductile-iron for use with ductile-iron pipe as specified above. Fittings <br />in the 3-inch through 24-inch size range shall be pressure rated at 350 psi, minimum; 30- <br />inch through 48-inch size range shall be pressure rated at 250 psi, minimum; and in the 54- <br />inch through 64-inch size range shall be pressure rated at 150 psi, minimum (except for <br />those fittings such as plugs, caps, and sleeves which are normally rated at a higher <br />pressure). No flanged fittings or mixtures of flanged with other end type fittings will be <br />allowed in the range of 3-inch through 48-inch since they are not covered in the AWWA <br />Standard. Flanged fittings conforming with and covered by this standard are allowed in sizes, <br />54, 60 and 64-inch. In conformance with the standard, 54, 60 and 64-inch flanged tees, <br />crosses and reducers with outlets of smaller dimension as listed in ANSI/AWWA <br />C153/A21.53-00 are permitted. All fittings with mechanical joints, flange joints and push-on <br />joints shall conform to ANSI/AWWA Standard C153/A21.53-00, "Ductile-Iron Compact <br />Fittings for Water Service". In addition, fittings with mechanical joints and push-on joints <br />shall conform to ANSI/AWWA Standard C111/A21.11-00, "Rubber-Gasket Joints for Ductile- <br />Iron Pressure Pipe and Fittings" except as otherwise allowed in C153. Mechanical joint <br />glands shall be ductile-iron only. <br /> <br />Since the C153 Standard provides only minimum dimensions, fully detailed drawings of all <br />fittings proposed shall be supplied by the manufacturer with his bid. The tabulated nominal <br />weight of each size and type of fitting shall also be supplied by the manufacturer for all items
