SECTION 3 ♦ Tool and Equipment List 2. A means of maintaining adhesive kits at 70°-80°F (21% 27°C). Use a box with a 25 watt light bulb, or keep the adhesive in a heated truck cab or building. 3. Heat assisted curing source a. electric heating collars -When using electric heating collars, make sure that an adequate power source is available and that extension cords are properly sized. Wattage requirements are as shown in Table 1.3.1. TABLE 1.3.1 Wattage Requirements for Electric Heating Collars As the length of the extension cord increases, the power lost in the cord increases. Table 1.3.2 shows maximum allowable length for various size cords. TABLE 1.3.2 Extension Cord Length Wire Size Size 110V or 220V Heating Collar (in.)

Chemical heat packs may leave residue on the pipe surface and are best suited for use where appearance is not a concern. Note: The overall effectiveness of chemical heat packs depends on ambient temperatures. Smith Fiberglass Products recommends using insulation when the ambient temperature (still air) or the wind chill is 32'17 (0°C) or below. Insulation is of- fered as an optional item by Smith Fiberglass Products. Each chemical heat pack is marked with an expiration date. Do not use kit after that date. 1.3.2 Recommended Equipment for Installing 2"-4" (50 mm -100 mm) Pipe (1) Available from Smith Fiberglass Products or your local distributor. 1. Chain vise (bench mounted or portable) capable of se- curing the pipe size used. Note: Use protective pads such as split sections of the same size fiberglass pipe or a sheet of X" (3 mm) thick rubber to protect the pipe from clamp or chain damage. 2. Tapering tool (see Section 5) 3. Felt-tip marking pen 4. Pipe cutting equipment a. fine-tooth (32 teeth/inch) hack saw, or b. circular saw with a crushed tungsten carbide or re- inforced abrasive blade, or c. sabre saw with a fine-tooth metal or tungsten car- bide grit blade, or d. jigsaw with carbide grit abrasive blade 5. Wrap-around (for marking pipe) 6. T.A.B. wrenches (see Section 6) 7. Shop hammer, 3-6 lbs. (4-9 kg), and a 2x4 block of wood 8. Adjustable pipe stands 9. Power drive adapter (optional) See Section S. 10. Electric heating collars SECTION 4 +JOINING METHODS 1.4.1 General Concepts 1. Proper Installation is the key to achieving a highly reli- able, adhesive bonded, matching taper, bell and spigot joint. 2. Matching taper angles on spigot and bell ends make it possible to lock-up a joint by wedging the spigot into the bell so that it takes significant force to separate them. Proper lock-up is essential. 3. A very thin line of adhesive (called the bond line or glue line) between the two matching tapered surfaces is essential to achieve optimum joint strength. 4. Cool weather installations require different bonding procedures from warm weather installations. See Section 6. S. Proper installation results in joint strength equivalent to or stronger than most piping systems. 6 Installation Instructions C •
