B. vac h. IelelevlevV Ivey l even TO SCREW TOGETHER 1. Properly instruct the crew in good installation techniques. A. Adhesive mixing. 1. When the weather is cool (70°F or below), pre -warm the adhesive kits. (Warm to the touch is sufficient.) 2. Empty the hardener can into the can of adhesive. 3. Mix all the adhesive with all of the hardener during the mixing process. 4. Wipe down the sides, bottom and under the rim of the can with the mixing stick. 5. Mix until the adhesive has a smooth flow off the mixing stick. B. Joint cleaning. NOTE: Solvent containers may be under pressure. Use caution when removing the inner seals. Eye protection is recommended. 1. Use sufficient cleaner and clean paper towels. 2. Clean all of the T.A.B. or tapered surfaces, both bell and spigot. 3. Remove oil, grease, mud, fingerprints, etc. 4. Once cleaned, do not touch the bonding surfaces. C. T.A.B. joint make-up. 1. Measure the length of the threads in the bell. 2. On the spigot, make a mark %i' longer than the bell thread mea- surement. 3. Prewarm the surfaces at temperatures below 70°F. Use a propane torch with flame spreader tip, electric heating collar or other handy heat source. Surfaces should be warm to the touch. Do not touch tapered surfaces to check (i.e., touch outside of bell or inside of spigot.) 4. Cover all machined areas on the spigot and at least %2" beyond the last thread in the bell with the adhesive. 5. Screw the pipe together by hand ensuring that you do not have the joint cross threaded. With 2" diameter RED THREAD II pipe you can tighten it with your hands until the mark on the spigot is no longer visible. On 3" and 4" RED THREAD II pipe use the T.A. B. wrenches to screw the pipe together until the mark on the spigot is no longer visible. Spigots must insert at least %4'. past the threaded portion of the bell. 6. Check lock-up by moving free end of pipe in an up and down or side to side motion. No movement should be visible in the joint. If any movement exists, continue to tighten until no movement is visible. Connections into fittings are made using the normal bell and spigot methods. (111 C) 11. Organize the crew for maximum efficiency. A. The man doing the cleaning should stay one joint ahead of the assembly crew and raise the free end of the pipe for good alignment. B. Organize the crew so that the adhesive is spread on the bonding surface as quickly as possible — particularly in extremely hot weather. C. Plan adhesive kit usage so that the crew won't have to wait while one man goes to get another kit. D. Plan ahead so that a sufficient number of bonds are available to use up one whole kit to avoid waste.
