shown on the Drawings. <br /> <br />1. Special adapters or wall fittings shall be provided by the piping <br />manufacturer. <br /> <br />C. Except where noted, wall pipes and castings shall be equipped with a water <br />stop and shall be ductile or gray cast iron for piping with nominal pipe sizes to <br />thirty (30) inches. <br /> <br />D. Wall sleeves shall be either galvanized steel, ductile or gray cast iron pipe and <br />shall have a water stop where required. <br /> <br />1. For wall sleeves through floors, the top of the sleeve shall be raised 4-inches <br />above finished floor elevation. <br /> <br />E. Wall pipes shall be of sufficient length to pass through the wall in accordance <br />with the details on the Drawings and shall conform to the details shown on the <br />Drawings. <br /> <br />F. The end of the wall pipes shall be of a type consistent with the piping to be <br />connected to them and shall conform to their standards and specifications. <br /> <br />G. Wall pipes shall have the same interior protection as specified for the <br />connecting piping. <br /> <br />H. Exterior protection shall be as specified for the yard or underwater piping. <br /> <br />2.10 WALL PENETRATION SEAL <br /> <br />A. Wall penetration seals shall be a modular mechanical type, consisting of <br />interlocking sealing links of an elastomer such as ethylene propylene and piene <br />monomer (EPDM) shaped to continuously fill the annular space between the <br />pipe and wall sleeve. <br /> <br />1. Links shall be loosely assembled with bolts to form a continuous rubber belt <br />around the pipe with a pressure plate under each bolt head and nut. <br /> <br />2. After the seal assembly is positioned in the sleeve, tightening of the bolts <br />shall cause the rubber sealing elements to expand and provide a watertight <br />seal between the pipe and sleeve. <br /> <br />3. The watertight seal shall be effective against a hydrostatic head of at least <br />40 feet. <br /> <br />4. The seal shall also be constructed so as to provide electrical insulation <br />between the pipe and wall, thus reducing chances of cathodic reaction <br />between these two members. <br /> <br />City of Sunny Isles Beach <br />NE 174th Street Roadway Improvements <br />15105 - 13 Pipes and Tubes <br />14-1758 / 09-19-2014 <br />
