Pressure Gauges shall be 4-1/2 inch gauge size, 0 to 100 psi range on pump discharge and 0 to <br /> 10 psi range on pump suction, stainless steel case, safety glass, brass movement, glycerin <br /> filled, industrial grade movement with 1.5% accuracy, and 1/2-inch NPT lower connection. ._ <br /> PART 3 — EXECUTION <br /> 3.01 PREPARATION AND HANDLING OF PIPE <br /> Each pipe and fitting shall be carefully inspected before the exposed pipe or fitting is installed or <br /> the buried pipe or fitting is lowered into the trench. The interior and exterior protective coatings <br /> shall be inspected, and all damaged areas, which are repairable in the opinion of the Engineer, <br /> shall be patched in the field with material similar to the original. Pipe unable to be repaired shall <br /> be removed from the project site and replaced with new, undamaged pipe. Clean ends of pipe -- <br /> thoroughly. Remove foreign matter and dirt from inside of pipe and keep clean during and after <br /> laying. _ <br /> Use proper implements, tools, and facilities for the safe and proper protection of the pipe. <br /> Carefully handle pipe in such a manner as to avoid any physical damage. Do not drop or dump <br /> pipe into trenches. <br /> 3.01 INSTALLATION OF PIPING <br /> A. General <br /> All pipe shall be carefully placed and supported at the proper lines and grades and, <br /> where possible, shall be sloped to permit complete drainage. Piping runs shown on the <br /> Drawings shall be followed as closely as possible, except for minor adjustments to avoid <br /> architectural and structural features. If major relocations are required, they shall be <br /> approved by the Engineer. - <br /> Wherever a pipe three inches in diameter and larger passes from concrete to earth, a <br /> flexible pipe coupling, shall be installed within 1 foot of the concrete. Particular care shall _ <br /> be taken to ensure a full support of the pipe in the earth between and beyond the joints. <br /> When installing buried PVC pipe, it shall be "snaked" in the trench. In addition, PVC pipe <br /> shall not be laid when temperature is 32°F, or below. <br /> Piping shall be installed without springing or forcing the pipe in a manner which would <br /> set up stresses in the pipe, valves, or connected equipment. <br /> B. Exposed Pipe <br /> Exposed pipe shall mean any pipe not buried or encased in concrete. <br /> In erecting exposed pipe a sufficient number of screw unions, flanged or grooved end <br /> type joints shall be used to allow any section or run of pipe to be disconnected without <br /> taking down adjacent runs. Flanges and grooved couplings shall be employed on pipes <br /> 2'/2 inches and larger. The provision of an adequate number of appropriate take-down <br /> fittings must be rigidly adhered to whether or not such fittings are indicated on the <br /> Drawings. Take-down fittings shall also be provided within two feet of threaded valves <br /> Division III-157 NEI Phase II Water and Sewer <br /> July 2007 CIP Nos. 7468, 7589, 7590 <br />
