CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: XX-XXXX PROJECT TITLE 175 Ductile iron pipe section shall be (18') and or (20') sections, except where shorter lengths are required to fit horizontal or vertical alignment. Pipe sections shall not be deflected at any joint, either vertically or horizontally, beyond the limits specified by the manufacturer. All pipe segments shall be sound and clean before laying. Ductile iron pipe cutting shall be done with a machine at right angles to the axis of the pipe. Cut end to be joined with a bell shall be beveled to conform to the spigot end. All fittings shall be mechanical joint (M.J.), or flanged (FLG) except where noted otherwise. All valves to fitting connections shall be flanged. Valves for lateral lines, hydrant leads and service lines shall be bolted directly to main line tee. Where it is necessary to install a reducer or other type of fitting between the lateral valve and main line, said fitting shall be flanged at both ends. No push-on joint fittings or connections shall be allowed unless specifically approved by the Engineer. All flanged fittings and connections shall comply with the applicable provisions of AWWA C110. The bolt circle and bolt holes of these flanges shall match those of the Class 125 flanges shown in ANSI B16.1. The Contractor shall coordinate the flange requirements with the connecting pipe and valve manufacturers. Contractor shall provide flange to connecting pipe adaptors as needed. Adaptors may be flange by connecting pipe fittings (e.g. FLG x M.J.) or Megaflange-Flange adapter. "E-Z Flange" and similar set screw type adaptors are not acceptable. Concrete thrust blocks shall be provided at all valves, fittings and hydrants in accordance with AWWA Standards and City of Santa Ana Standard Plan Nos. 1412 and 1420. Type V cement shall be used for all concrete thrust blocks. Where called for on the plans, a high -early strength concrete shall be used for thrust blocks at points of connection. Admixtures for high-early strength concrete shall be non- chloride admixtures which meet the requirements of ASTM C494. Acceptable products are Pozzutec 200 and Pozzolith NC 534 by Master Builders, Inc. or approved equal. Concrete shall reach 2,500 psi by four (4) hours. For restrained mechanical joint fittings, the mechanical joint fitting shall be fitted with joint restraints. Mechanical joint restraint shall be incorporated with the design of the follower gland and shall include a restraining mechanism which, when activated, imparts multiple wedging action against the pipe, increasing its resistance as the pressure increases. The joint shall maintain flexibility after burial. Follower glands shall be manufactured of ductile iron conforming to ASTM A536-80. The mechanical joint restraint shall be EBBA IRON, Inc., MEGALUG, UNIFLANGE Series 1400, The Ford Meter Box Co., Inc. or approved equal. Any restrained joint fittings which require a pipe field weldment will not be permitted. 505 E Central Ave #B11/6/2024
