C u A. B. VI. A. B. Note: Avoid point loading the adapterwhen using a nylon strap wrench to tighten. Flanges — Before bonding onto the RED THREAD II pipe, make sure the bolt holes line up with the mating bolt holes on the steel flange. Use %" thick, full face 60-70 clurometer gaskets that are 'chemically compatible with the fluid going through the line. Saddles— Join only to RED THREAD II pipe using adhesive DS -7014, DS -7024 or DS -7069. Threaded connections must be (rade with a flexible connector such as flexible hose to eliminate bending stress. Tighten threads as if they were brass or other soft material: Torque to 35 ft./lbs. Locate saddle on pipe and mark around saddle base. Use a file or rough sandpaper(40 to 60 grit) to remove all surface gloss from the pipe 0. D. where the saddle is to be bonded. Use circular or random pattern during sanding to eliminate grooves on the pipe surface. Aftersanding, locate saddle on pipe and mark hole to be cut in pipe. Cut a' hole of the same size as the outlet of the saddle using a pilot drill and circular hole saw. Do not force the cutter or it will unduly fray the edges of the hole. Clean all bonding surfaces with joint cleaner. Apply a heavy coat of adhesive to the 0. D. of the pipe, I. D. of the saddle and the edges of the pipe wall exposed by the hole. Place the saddle over the hole and clamp with two hose clamps. Using a large screw driver, hand tighten the clamps alternately until secure and adhesive squeezes; out all the way around the saddle. This will insure that.the pipe O.D. conforms to the 1. D. of the saddle. The clamps may be removed after the bond is cured and after the flexible connector is installed in the outlet. Inspection. During transportation, storage and handling, pipe can sometimes incur rough treatment. Therefore, all pipe must be inspected for possible damage to the bell, the spigot orthe pipe wall. Damaged sections must be cut out or repaired. If in doubt about damage, contact!your local distributor. If pipe orfittings have been exposed to weather or sunlight for an extended or unknown period of time, the following ;corrective actions must be taken before installation and immediately prior to bonding: If spigot is exposed, cut 1 " off the end and retaper. This will remove the surface degradation layer and give a fresh surface for bonding. If bell of pipe or fitting is exposed, sand thoroughly until the entire surface appears fresh. A flapper sander of about 40 grit mounted on an electric hand drill works well. T.A.B bells should be cut off, pipe tapered and a sleeve coupling bonded on. Repairs. On buried lines a permanent repair should be made before the line is covered. If the damage covers a small area, proceed as follows: 1. Cut a length of good pipe long enough to adequately ;cover the damaged area and extending at least 2" (and preferably 4',') beyond either side of damaged area.
