SECTION S • SECONDARY CONTAINMENT SYSTEM SIZE Containment saddles must be installed prior to bonding and testing the product piping. Use DS -7000 series adhesive or DS -8000 series adhesive when bonding saddles to the pipe. Threaded connections must be made with a flexible connector such as flexible hose to eliminate bending stress. Tighten threads as if they were brass or other soft material. Procedure for installing secondary containment saddles: Refer to Fig. 2.6.2. 1. Locate saddle on pipe and mark around saddle base. 2. Use a file or rough sandpaper (40 grit or less) to re- move all surface gloss from the pipe O.D. where the saddle is to be bonded. Use circular or random pattern during sanding to eliminate grooves on the pipe sur- face. 3. After sanding, locate saddle on pipe and mark hole to be cut in pipe. Using a pilot drill and a fine-tooth cir- cular hole saw, cut a hole of the same size as the outlet of the saddle. Do not force the cutter, or it will unduly fray the edges of the hole. 4. All bonding surfaces must be free of contamination. See Section 7, Para. 2.7.2. 5. Apply a heavy coat of adhesive to the O.D. of the pipe, I.D. of the saddle, and the edges of the pipe wall ex- posed by the hole.
