TABLE 9. Make-up Dimensions (Wet) This added length is needed due to additional insertion that occurs because the adhesive acts as a lubricant. CAUTION: This additional insertion will be greater if a tight, dry fit is not achieved when measuring. After the final nipple length is determined, cut the other end of the nipple and taper it, making sure the nipple is on the tapering tool in exactly the ser ne position as the first taper that was used to measure the insertion length. If solvent is used to clean bonding surfaces, allow the cleaner to evaporate. Apply adhesive to all bonding surfaces and insert the nipple into the line by lifting the line or moving it to one side. Pushing the pipe back into the line will push the nipple into the bell. Make certain all tapers are tightly locked. Replace the protective mesh covering If the repair is made on 2" pipe. Leaking Joints Any adhesive -bonded joint that leaks during pressure testing MUST BE REMOVED AND REPLACED. Follow the previous procedures using two sleeve couplings and pipe nipple. After completing any necessary repairs to the piping system, follow the proper testing sequence to verify the system's integrity. PART TWO INSTALLATION INSTRUCTIONS FOR Red Thread IIA SECONDARY CONTAINMENT PiPING The secondary containment piping system is designed for use with Red Thread IIA product pipe. The system consists of the next larger size pipe and special two-piece fittings. Many of the procedures used for installing primary product pipe and fittings are also used for installing secondary containment pipe and fittings. Refer to these sections and to Bulletin Nos. F6625 or F6624 for tapering tool operating instructions. Following are useful sections previously outlined: Storage and Handling (page 1) Layout and Preparation (pages 2-3) Tool and Equipment List (page 3) For installation of bolts, the following is recommended: • Variable speed impact wrench with 9/6" socket • Variable speed drill motor with 918" socket One 90' wrench For installing saddles, the following is recommended: • Sanding equipment: - power sander with rough surface sanding disk (flexible pad with 40 grit or less disk), or - hand file (coarse) • Fine tooth circular hole saw with pilot drill Hose clamps or Band -Its banding tool large enough to secure saddles to pipe. (if banding is used, the Band -It banding tool is preferred as this tool does not allow slack in ttie band when the tool is removed. Two Band -It tools are recommended so the saddle can be pulled down uniformly. Use 3/4" (19 mm) banding. (Band -It inforrnation is available at www.band-it-index.com).

Prit-nary Pipe Size 3" 75 mm 2" 50 mm 4" 100 mrn 75 mrn 6" 150 mm 4" 100 nurr Secondary Containment Fittings Available secondary containment fittings are tees, 90" elbows, 45' elbows, couplings, nipples, concentric reducers, termination fittings (with or without 3/4" NPT threaded outlet), saddles (belled or with NPT threaded outlets), and sump entry termination fittings. Inserts are required on 3" and 4" 901 elbows and tees for Closed Interstitial Monitored Systems. Inserts are not required for Open Gravity Flow Systems. Adhesive for Secondary Containment Piping When joining secondary containment pipe -to -fittings and fittings -to -fittings, fiberglass filler must be added to the 7000 or 8000 series adhesive to ensure optimum performance of this type of bonded 'joint. Filler is available from NOV Fiber Glass Systems. Due to the quantity of adhesive required for joining secondary containment fittings„ it is recommended that only 7069 or 8069 kits be used (See Table 13 on page 16). If 7014 and 8014 kits are used, please note that extra kits (50% more than 7069 or 8069) must be used for each secondary containment fitting. LAYOUT AND PREPARATION Before installing the secondary containment piping system, review and verify the recommendations for proper installation set forth previously: Layout and Preparation (Installation Crew Size and Organization) (page 2) Piping Layout, Pipe Trenches and Burial (pages 4-5) Most of the standard procedures for installing a secondary containment piping system can be handled by the same size crew that would install a single -wail product piping system. It is essential that each phase of an installation be evaluated and the proper number of workers be assigned to assure an efficient installation. U.
