It will also be <br />different for each size of pipe.) <br />After the final nipple length is determined, cut the other <br />end of the nipple and taper it, making sure the nipple is on <br />the tapering tool in exactly the same position as the first <br />taper that was used to measure th e insertion length. <br />— If solvent is used to clean banding surfaces, allow the <br />cleaner to evsir rte. Apply adhesive to aN bonding <br />surfaces and insert the nipple Into the Ina by Offing the <br />Una or moving it to one sWe. Pushing the pipe back into <br />the line will push the nipple into the bell. Make certain ar <br />tapers are tightly locked. <br />01 Replace the protective meO covering if the repair <br />made on 2" pipe. <br />Leaking Joints <br />Any adhesive -bonded joint that leaks during pressure <br />testing MUST BE REMOVED AND REPLACED. Followthe <br />previous procedures using two sleeve couplings and pipe <br />nipple. <br />After completing any necessary repairs to the piping <br />system, follow the proper testing sequence to verity the <br />system's integrity. <br />15 <br />PART TWO <br />INSTALLATION INSTRUCTIONS FOR <br />RED THREAD IIA <br />SECONDARY CONTAINMENT PIPING <br />Before beginning an installation, it is important <br />that all crew members read and be familiar with the <br />installation procedures described in this manual. <br />The secondary containment piping system is designed <br />for use with RED THREAD IIA product pipe. The system <br />consists of the next larger size pipe and special two-piece <br />clam shell fittings. <br />Many of the procedures used for installing primary <br />productpipe and fittings are also used for installing secondary <br />containment pipe and fittings. Refer to these sections and <br />to Bulletin Nos. F6625 or F6624 for tapering tool operating <br />instructions. <br />Following are useful sections previously outlined: <br />Storage and Handling (page 1) <br />Layout and Preparation (pages 2-3) <br />Tool and Equipment List (page 3) <br />For Installation of baits, the following is recommended. <br />0 3/8" variable impact wrench with 3/8" socket <br />0 1/4" variable speed drill motor with 3/8" socket <br />0 One 318° wrench <br />For instafling saddles, the following is recommended. <br />Sanding equipment: <br />— power sander with rough surface sanding disc (flexible <br />pad with <br />0. or less disc), or <br />—hand file (coarse) <br />Fine tooth circular hole saw with pilot drill <br />Hose clamps or Band -It banding tool large enough to <br />secure saddles to pipe. (If banding is used, the Band -it <br />banding W Is preferred as this tool does not leave slack <br />in the bond whan the tool is removed. Two Band -It <br />tools are recommended so the saddle can be pulled down <br />uniformly. UseAW (119 mm) banding. (Band4t information <br />is available at www.band-it-idex.com.) <br />Cutting and Tapering (page 4) <br />Installation (piping layout and trench design; adhesive <br />mixing and curing) (pages 5-11) <br />(Secondary Containment Pipe <br />FGS Smith Fibercast secondary containment piping sizes <br />are as follows: <br />Containment Pipe Size <br />Primary Pipe Size <br />3" 75 mm <br />2" 50 mm <br />4" 100 mm <br />3" 75 mm <br />6" 150 mm <br />4" 100 mm <br />
