Refer to individual Division 22 piping Sections for special joining materials not listed below. <br />B. Pipe -Flange Gasket Materials: Suitable for chemical and thermal conditions of piping system <br />contents. <br />1. ASME B16.21, nonmetallic, flat, asbestos -free, 1/8 -inch maximum thickness unless <br />thickness or specific material is indicated. <br />a. Full -Face Type: For flat -face, Class 125, cast-iron and cast -bronze flanges. <br />b. Narrow -Face Type: For raised -face, Class 250, cast-iron and steel flanges. <br />2. AWWA C110, rubber, flat face, 1/8 inch thick, unless otherwise indicated; and full -face or <br />ring type, unless otherwise indicated. <br />C. Flange Bolts and Nuts: ASME B18.2.1, carbon steel, unless otherwise indicated. <br />D. Solder Filler Metals: ASTM B 32, lead-free alloys. Include water-flushable flux according to <br />ASTM B 813. <br />E. Solvent Cements for Joining Plastic Piping: <br />1. CPVC Piping: ASTM F 493. <br />2. PVC Piping: ASTM D 2564. Include primer according to ASTM F 656. <br />2.3 TRANSITION FITTINGS <br />AWWA Transition Couplings: Same size as, and with pressure rating at least equal to and with <br />ends compatible with, piping to be joined. <br />1. Underground Piping NPS 2 and Larger AWWA C219, metal sleeve -type coupling. <br />B. Flexible Transition Couplings for Underground Nonpressure Drainage Piping: ASTM C 1173 <br />with elastomeric sleeve, ends same size as piping to be joined, and corrosion -resistant metal <br />band on each end. <br />2.4 DIELECTRIC FITTINGS <br />A. Description: Combination fitting of copper alloy and ferrous materials with threaded, solder - <br />joint, plain, or weld -neck end connections that match piping system materials. <br />B. Insulating Material: Suitable for system fluid, pressure, and temperature. <br />C. Dielectric Unions: Factory -fabricated, union assembly, for 250-psig minimum working pressure <br />at 180 deg F. <br />D. Dielectric -Flange Kits: Companion -flange assembly for field assembly. Include flanges, full- <br />face- or ring -type neoprene or phenolic gasket, phenolic or polyethylene bolt sleeves, phenolic <br />washers, and steel backing washers. <br />Separate companion flanges and steel bolts and nuts shall have 150- or 300-psig <br />minimum working pressure where required to suit system pressures. <br />COMMON WORK RESULTS FOR PLUMBING 220500 - 3 <br />
