Primary Piping System Installation <br /> NN TOOTHE SYS C S <br /> The use of flat washers on all nuts and bolts is required. <br /> Adapters available for connecting to other systems include The maximum allowable torque is indicated on each <br /> the following: threaded adapters(bell or spigot by NPT or flange. <br /> BSP threads),reducer bushings(NPT),and flanges. <br /> Smith Fibercast flanges meet ANSI 816.5 Class 150 bolt <br /> NOTE: When using adapters with spigot ends,it may be nec- hole standards.

Otherwise,un- <br /> less a union is used,it may be impossible to turn the <br /> adapter into the mating thread. You will obtain best re- <br /> sults using a strap wrench and a solvent-free,soft-set, <br /> non-metallic thread lubricant. The thread lubricant must <br /> be chemically resistant(compatible)with the petroleum or <br /> alcohol product conveyed in the piping system. Do not <br /> use thread sealing tapes. For best results,apply thread <br /> lubricant to both the male and female threads. Smith <br /> Fibercast 7000 or 8000 series adhesive may be used in <br /> place of thread lubricant. <br /> Tighten threads 1 to I 1 turns past hand tight to ensure a <br /> proper seal. Do not use metallic wrenches to tighten <br /> threaded adapters,as this may cause damage to the fitting. <br /> CAUTION: Do not over tighten. Tighten the <br /> ■ adapters as if they were brass or other soft material. <br /> NOTE: When using threaded reducer bushings,the bush- <br /> ing should be BONDED AND CURED before the male <br /> thread is screwed into the bushing. <br /> You can use adhesive instead of thread lubricant on thread- <br /> ed adapters. Be certain to tighten the threaded adapters as <br /> with standard thread lubricant. <br /> B. Flanges <br /> Before bonding the flange onto the <br /> pipe,make sure the bolt holes line up <br /> with the mating bolt holes on the other <br /> system. Do not bolt the flange before <br /> bonding unless insertion depth of the spigot is <br /> previously checked to be certain that the spigot does not bot- <br /> tom out or extend throWh the flange. <br /> (1)Teflon is a registered trademark of E.i.DuPont de Nemours Co. <br /> RED THREAD IIA Pipe & Fittings 12 <br />
