2.16 INSULATING FLANGE COATING SYSTEM <br /> A. Coatings for buried insulating flanges and insulating couplings shall consist of a four <br /> part, non-conductive, petrolatum-based coating system. The four part coating <br /> system shall consist of a prime coat as an initial surface preparation to displace <br /> moisture on the surface. A fill material shall be used as required to provide a <br /> smooth contour on the surface of the joint. A wrap material shall be used for <br /> protection of the substrate. A guard material shall be used as a final coating to <br /> provide increased mechanical strength of the coating. <br /> B. The prime coat shall be a petrolatum material with corrosion inhibitors and inert <br /> fillers. The material shall be free of acids, alkalies, waxes and resins. The fill <br /> coat shall be a Petrolatum material with inert fillers and reinforcing fibers.

All materials and equipment to be used in construction shall be stored in such a <br /> manner to be protected from detrimental effects from the elements. If warehouse <br /> storage cannot be provided, materials and equipment shall be stacked well <br /> above ground level and protected from the elements with plastic sheeting or <br /> other method as appropriate. <br /> 3.03 PREPACKAGED ZINC ANODES <br /> A. Prepackaged zinc anodes shall be installed in the trench horizontally after <br /> excavation to proper depth. The top of the anode shall be a minimum of 5 feet <br /> below grade and a minimum of 5 feet from the pipeline. Spacing between <br /> anodes shall be 10 feet, center to center, installed vertical or 5 feet end to end, <br /> installed horizontal. Prior to placing anodes in the trench, paper or plastic bags <br /> shall be removed, but the cloth bag shall remain around the anode. Care shall <br /> be exercised during installation to prevent damage to the cloth bag and loss of <br /> backfill material. After placing anodes in the trench, native soil, free of rocks and <br /> July 2007 Division III-142 NEI Phase II Water and Sewer <br /> CIP Nos. 7468, 7589, 7590 <br />
