NOTE: If T.A.B. wrenches are not available, strap wrenches, such as Ridgid "' No.2-P, can be used. (See Figure 1.6.15). To prevent damage to the pipe wall, wrap the strap wrench around the pipe as shown in Figure 1.6.15. CAUTION: im- proper use of strap wrenches can cause point -loading damage and/ or bad joints that are not locked up. In order to gain experience in deter- mining the properamount of torque to use, the following procedure is recommended for the fi rstfewjoi nts. DO NOT OVERTIGHTEN. a. Cover all machined areas on the spigot and at least 1/2 -inch (13 mm) beyond the last thread in the bell with adhesive. b. Screw the pipe together by hand, ensuring that the joint is not cross-threaded. Two inch (50 mm) diameter pipe can be hand tightened. To ensure complete joint make-up for 3" and 4" (75 and 100mm) diameter pipe, T.A.B. wrenches should be used. c. Check lock-up by moving free end of pipe in an up-and-down or side-to-side motion.

No movement should be vis- ible in the joint. If any move- ment exists, continue to tighten until no movement is visible. Connections into fittings are made using the normal bell and spigot meth- ods. 1.6.5 Adhesive cure time Cure time is the time required for the adhesive in the assembled joint to harden. Cure time depends on the type of adhesive and the ambient temperature, as shown in the follow- ing chart (See Figure 1.6.16) IMPORTANT: When using RED THREAD IIA piping for alcohol and alcohol/gasoline mixtures, three ad- hesive systems are available. DS - 8000 series adhesive may be used for primary and secondary containment joints. DS -4000 series adhesive may be used for pLLmary joints. DS -7000 series adhesive may be used for secondary containment systems. DO NOT USE DS -7000 series adhe- sive for primary systems conveying alcohol and DO NOT USE DS -4000 series adhesive for secondary con- tainment systems. In other words, it Figure 1.6.16 L Ridgid is a registered trademark of the Ridge Tool Co. Figure 1.6.17 16 is necessary to use DS -4000 series adhesive for primary joints and DS - 7000 series adhesive for secondary containment joints. DS -8000 series adhesive can be used for either. Reusable heating collars are energized by a 110/120 volt power source.f2' (See Figure 1.6.17). We recommend external heat to as- sure full adhesive cure when ambient temperature is below 70°F (21 °C). It is desirable but not necessary for the curing operation to immediately follow the bonding operation. How- ever, it is preferable to bond only that amount of pipe and fittings that can be cured during the same day. 1. Curing pipe joints a. Center the heating collar around the bonding area of the joint to be cured (See Figure 1.6.18). Repeat this step for all joints to be cured. b. Plug the heating collar into a 110/120 volt outlet. c. Heat the joints for the length of time listed in Table 1.6.3. NOTE: These cure times are calculated using heating col- lars from Smith Fiberglass Prod- ucts. These heating collars can reach a maximum temperature of 330°F 0 660C). Using heat - Figure 1.6.18 d1 Note: 220/240 volt heating collars are available on special order. 240 volt collars are shipped without male plug. F_
