Dimensions shall conform to the requirements of ANSI A21.6, ANSI A21.8, ANSI A21.11, <br /> and WW-P-421 C, as applicable. Dimensions shall be gaged at sufficiently frequent <br /> intervals to assure dimensional control. Insides of sockets and outside of spigot ends <br /> shall be tested with circular gages. <br /> E. Wall thickness shall be determined for the design working pressing and depth of cover <br /> shown in accordance with ANSI requirements for each type. <br /> F. Each pipe shall be coated on the inside and outside with standard bituminous coating of <br /> either coal-tar of asphalt base approximately one mil thick. The coating shall be <br /> continuous, smooth, strongly adherent to the pipe and shall not become brittle from cold <br /> nor sticky from heat. As indicated, the interior coating shall be Protecto 401 ceramic <br /> lining as manufactured by U.S. Pipe, Sewper Coat as manufactured by Lafarge Calcium <br /> Aluminum, or equal. All linings and coatings shall be per manufacturer's specifications <br /> and conform to ANSI/AWWA C151/A21.51. <br /> G. Each pipe shall be weighed prior to placing of the inside lining.

Where flanged ends may be required, <br /> flanges shall conform to applicable requirements of ANSI B16.1 and ANSI B16b. <br /> 2.5 GRAY CAST IRON FITTINGS <br /> Gray cast iron fittings shall conform to the requirements of ANSI Specification A21.10, with <br /> mechanical joint ends conforming to ANSI Specification A21.11. They shall be of 18/40 gray iron. <br /> All fittings shall be bituminous coated as required for pipe. Where flanged ends may be required, <br /> flanges shall conform to applicable requirements of ANSI B16.1 and ANSI B16b. <br /> 2.6 PVC FITTINGS <br /> PVC fittings and adapters shall conform to the same requirements as for pipe and shall be the <br /> same class as the pipe. <br /> Orange County DAA PN R00592-225N2 <br /> Walnut Grove Wastewater System January, 2021 <br /> 33 34 00-4 <br />
