• Note: If connecting cc surface where the asses bending forces, flexibl( hoses) must be used tc SECTION 6 ♦ Secondary Containment Saddles squeezes out all the way around the saddle. This will ensure that the pipe O.D. conforms to the I.D. of the sad- dle. The clamps may be left on or re- moved after the bond has cured and after the flexible connector is installed in the outlet. Caution: Product pipe may be un- der pressure if the testing has been completed. Do not attempt to in- isstall a saddle on the containment pipe if the product piping system has been in- stalled and tested. SECTION 7 • ADHESIVE BONDING AND CURING 2.7.1 Introduction Before bonding the two-piece containment fittings, the installation procedures should be reviewed with the in- stallation crew members. In order to maintain the effi- ciency of the installation, a minimum of three workers is recommended: one worker to mix and apply adhesive to the secondary containment fittings, and the two re- maining workers to assemble and bolt the fittings to- gether. For secondary containment systems conveying alcohols or alcohol/gasoline blends, use DS -8000 series or DS -7000 se- ries adhesives. (NOTE: For primary systems conveying al- cohols or alcohol/gasoline blends, use only DS -8000 series adhesive.) Follow the adhesive mixing instructions that are packaged with each kit. FILLER MUST BE ADDED TO THICKEN THE ADHESIVE. The filler is packaged in premeasured quantities for use with DS -7014 or DS -8014 and DS -7069 or DS -8069 adhesive kits. One bag of filler is used for each adhesive kit. Before adding the filler to the mixed adhe- sive, be sure both the adhesive base and hardener are thor- oughly mixed together. All of the filler in the bag should 4 i � Q � . Y F FIGURE 2.6.1 FIGURE 2.6.2 be used. The thickened adhesive may be applied with ei- ther the brush or the stir stick provided in the kit. Refer to Table 2.7.1 for the number of containment fit- tings that can be bonded per adhesive kit. Note: Number of containment fittings per adhesive kit is based on applying a X6" (1.6 mm) minimum thickness of adhesive to both halves of the fitting and to the pipe ends. 2.7.2 Cleaning the Bonding Surfaces Smith Fiberglass Products has determined that cleaning the bonding surface is required only when the bonding surfaces, on either pipe or fittings, have been contaminat- ed by grease, oil, dirt, fingerprints, etc. Freshly tapered spigots or scarfs or factory -fresh spigots, scarfs, or bells do not require solvent cleaning unless visibly contaminated. DO NOT TOUCH THE BONDING SURFACES OR ALLOW THEM TO BECOME CONTAMINATED. Acceptable cleaning methods for containment piping are as follows: • Sand all bonding surfaces until contaminated area is removed. RED THREAD HA Pipe & Fittings ow 27
