Primary Piping. System Installation <br /> CONNECTING TO OTHER SYSTEMS <br /> Adapters available for connecting to other systems FGS Smith Fibercast flanges meet ANSI 816.5 Class <br /> include the following: threaded adapters (bell or spigot 150 bolt hole standards. Full-face Basketing materials, <br /> by NPT or BSP threads), reducer bushings (NPT), and 1/8" (3 mm) thick, with a Shore A hardness of 60 to 70 <br /> flanges. durometer, are recommended for flanges. Gaskets <br /> made from Teflon and PVC usually have high durometer <br /> NOTE: When using adapters with spigot ends, it may be ratings and are not acceptable. <br /> necessary to cut off a portion of the factory pipe bell if the <br /> threads are not fully exposed. Connecting to Flat-Face Flanges - FGS Smith <br /> Fibercast flanges must be joined to flat-face flanges. <br /> • Threaded Adapters (NPT or BSP) and Reducer The recommended maximum torque is listed on the <br /> Bushings(NPT) flange label. <br /> Before making up threaded 01 El <br /> connections, inspect the threads. Connecting to Pump/Dispenser <br /> Do not use fittings with damaged Several methods are available to connect the product <br /> threads. Inspect all steel [393 piping lines and vent/vapor recovery lines to the <br /> threads and remove any burrs. underground storage tank and dispenser: fiberglass <br /> Threads must be clean and dry fittings,flexible connector, steel fitting or swing joint. <br /> before applying thread lubricant. Use of flexible connectors at each location facilitates <br /> When using threaded adapters, ease of installation. <br /> thread them into the other system before bonding onto <br /> FGS Smith Fibercast pipe. Otherwise, unless a union is <br /> used, it may be impossible to turn the adapter into the <br /> mating thread. You will obtain best results using a strap <br /> wrench and a solvent-free, soft-set, non-metallic thread <br /> lubricant. The thread lubricant must be chemically <br /> resistant (compatible) with the petroleum or alcohol <br /> product conveyed in the piping system. Do not use <br /> thread sealing tapes. For best results, apply thread <br /> lubricant to both the male and female threads. FGS <br /> 7000 or 8000 series adhesive may be used in place of <br /> thread lubricant. <br /> Tighten threads 1 to 11/2 turns past hand tight to ensure <br /> a proper seal. Do not use metallic wrenches to tighten <br /> threaded adapters as this may cause damage to the <br /> fitting. <br /> CAUTION: Do not over tighten. Tighten the adap- <br /> ters as if they were brass or other soft material. <br /> NOTE: When using threaded reducer bushings,the bushing <br /> should be BONDED and CURED before the male thread <br /> is screwed into the bushing. Adhesive instead of thread <br /> lubricant may be used on threaded adapters. Tighten the <br /> threaded adapters as with standard thread lubricant. <br /> • Flanges <br /> Before bonding the flange onto the <br /> pipe, make sure the bolt holes line <br /> up with the mating bolt holes on the o 0 <br /> other system. Do not bolt the flange <br /> before bonding unless insertion depth of the spigot is <br /> previously checked to be certain that the spigot does not <br /> bottom out or extend through the flange. <br /> The use of flat washers on all nuts and bolts is required. <br /> The maximum allowable torque is indicated on each <br /> flange. <br /> 11 <br />
