Alternate Termination Termination of the secondary containment piping system at the storage tank is accomplished using a termination fitfing with 3W female NPT threaded outlet. See figure below. The 3/4" threaded outlet allows easy access for pressure testing of the secondary containment piping system and may also be used as an access for a leak detection probe. TABLE 12. Termination Fitting Conneotions ") A scarfed O.D. BxM adaptor or coupling is avaliabie for use with the termination fittings. SECONDARY CONTAINMENT REDUCERS In-line secondary containment pipe size reductions are made using a concentric reducer. Reductions can be made from 6" to 4" (150 mm to 100 mm) and 4" to 3" (100 mm to 75 mm). Both ends of the concentric reducer are bonded to scarfed end of pipe. SECONDARY CONTAINMENT SADDLES For secondary containment piping installations requiring inter- mediate access stations for visual or electronic leak detection. several sizes of reducing saddles are available. See Manual No. 2101 for saddle sizes and descriptions. Note: If connect- ing components, extend to the surface where the assembly can be subjected to bend- ing forces, flexible connectors (such as flexible hoses) must be used to eliminate bending stress. Containment saddles must be installed prior to bonding and testing the product piping. Procedure for installing secondary containment saddles: • Locate saddle on pipe and mark around saddle base. • Use a file or rough sandpaper (40 grit or less) to remove 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 surface. • After sanding, locate saddle on pipe and mark hole to be cut in pipe. Using pilot drill and a fine-tooth circular hole saw, cut a hole of the same size as the outlet of the saddle. Do not force the cutter or it will fray the edges of the hole. • All bonding surfaces must be free from contamination. • 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 exposed by cutting 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 ensure the pipe O.D. conforms to the I.D. of the saddle. The clamps may be left on or removed after the bond has cured. Do not attempt to install a saddle on the oontainment pipe if the produot piping system has been installed and tested. JOINT PREP Installation Preparation Before bonding the two-piece containment fittings, the installation procedures should be reviewed with the installation crew members. in order to maintain the efficiency 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 remaining workers to assemble and bolt the fittings together. Cleaning the Bonding Surfaoes It is recommended that all bonding surfaces are cleaned before bonding. DO NOT TOUCH THE BONDING SURFACES OR ALLOW THEM TO BECOME CONTAMINATED. Acceptable cleaning methods are as follows: • Sand all bonding surfaces until contamination is removed. • Dirt contamination can be removed by water washing. Be sure the surfaces are dry before bonding. • Sand all machined ends that have been exposed to sunlight and have turned yellow or brown in color. • Use of a solvent as a cleaning method is optional. Some cleaning solvents are acetone, alcohol, methylene chloride, and methyl ethyl ketone. After cleaning, be sure any residual solvent has evaporated before applying adhesive. DO NOT USE SOLVENTS THAT LEAVE AN OIL FILM ON THE BONDING SURFACES. WARNING: Some degreasers and solvents are extremely flammable. Be sure to read warning labels on containers. Never use gasoline, turpentine or diesel fuel to clean joints. Contact your representative if you have questions.
