After cleaning all sanded surfaces with the cleaner supplied in the adhesive kit, apply a thick coating (1/16" minimum) of ad- hesive to the socket (bell) area of the fitting. Liberally coat the tabs (flat bonding surfaces) of both halves of the fittings with adhesive (1/16" minimum thickness). (See Figure 4) Next, ap- ply a thick coating (1/16" minimum) of adhesive to the sanded surfaces of the pipe ends. NOTES: 1. The stir stick supplied with the adhesive kit works well as an applicator. 2. Two-piece containment fittings require more adhesive than is normally used with Smith Fiberglass Products bell and spigot joints. Use the bolts, nuts and washers to assemble the fittings on the pipe. Two 7/16" wrenches are required for the bolts. Note that a flat washer is required on both halves of the fittings. (See Figure 4) Tighten the nuts and bolts completely. A variable torque impact wrench will greatly increase the efficiency of this operation. Make sure that adhesive fills any gaps between pipe ends and fitting sockets. Care should be taken not to disturb a completed contain- ment piping joint when assembling additional joints. The adhesive must be fully cured before applying stress to assembled joints. Precautions: 1. Avoid contact with the adhesive and hardener since they are capable of causing skin and eye irritations. Gloves and eye protection are sug- gested. If contact is made, flush with water and wash with soap and water. Although the hardener is only mildly toxic, avoid inhaling fumes by working in well ventilated area. Solvent containers may be under pressure. Use caution when opening. Wear eye protection. In case of accidental exposure, flush with plenty of water and seek medical attention if irritation develops. Use with adequate ventilation. Avoid breathing vapor. Avoid contact with skin. Wash thoroughly after handling and before eating or smoking. E. Adhesive Cure Cure time is dependent on ambient temperature. Cure time at 75° F is 4 to 5 hours. For cure cycle curves, refer to the in- structions in the adhesive kits. Use of external heat (such as hot air guns) will shorten the cure times and is highly recom- mended for all installations where the temperature is below 70°F. External heat is essential for temperatures below 60°F. Direct flames should not be used to cure the adhesive. Hot spots may cause overheating of the adhesive resulting In a bad bond. Pipe sections should not be handled or stressed until the glue line has returned to ambient temperature. overtighten when installing the pipe threads. Fiberglass threads may be damaged during removal if overtightened. Smith Fiberglass Products recommends testing 3"-6" second- ary containment piping systems with air at pressures up to 10 psig. The most convenient place to introduce air for the con- tainment piping pressure test is at the bulk storage tank (See Figure 5). It is advantageous to leave the system pressurized until the installation is complete in order to monitor for possi- ble damage during additional construction. The low pressure and low volume of secondary containment piping systems make this air test a safe procedure if normal safety pro- cedures are followed. 10 psig Figure 5 SECTION III TERMINATION FITTINGS Termination at the bulk tank connections is accomplished by using a termination concentric reducer with 3/4' female NPT threaded outlet. (See Figure 6) Fiberglass Threaded Adapter (Bell x Male) O=__0_1'__a_ NPT Tank O O O Figure 6 Testing Y-6" secondary containment piping can be pressure tested by Termination at the dispenser may be accomplished with a gasoline installing an in-line tee with a pressure gauge in the 3/4" outlet resistant boot, clamped and bonded in place (See Figure 8), or by of a termination fitting (Figure 5). This test piping may be using a termination concentric reducer (See Figure 9).
