11 4.0 FLEXWORKS PIPE ACCESSORIES There are a variety of accessory components which may be used with OPW-FCS's flexible piping systems. 4.1 Standard Test Boots and Reducer Test Boots When OPW-FCS's double wall flexible piping is fitted with swivel couplings, you can incorporate the use of rubber test boots and small diameter plastic tubing to provide access to the interstitial space of the double wall piping. One end of the rubber test boot clamps down onto the outside of the secondary jacket and the other end of the boot is clamped onto the outside of the ferrule of the swivel pipe coupling. The test boot includes a rubber boot and two band clamps. NOTE: The test boots are not used with single wall piping or coax fittings & couplings. 4.2 Test Tubes These 36" long plastic tube assemblies are designed to provide access to the beginning and end of the interstitial space of double wall pipe for initial and periodic air pressure testing. There are two types of test tubes available for use. One type is used with test boots and fitted with a barbed elbow and stainless steel band clamp on the lower end for insertion and«, clamping into the test boot port. The other type, the coax test tube is used with the coax pipe adapter and fitted with a 1/4" NPT male nylon threaded fitting for connection to the threaded test port. 4.3 Connector Tubes These short plastic tube assemblies are designed to reroute the interstitial space of, one double wall flexible pipe section around a metallic junction tee fitting to the next double wall flexible pipe section. They come fitted on each end with a barbed air stem coupling elbow and stainless steel band clamp for insertion and clamping into the test boot port. NOTE: The connector tubes are not used with single wall pipe and coax fittings and couplings. 4.4 Crossover Supports These two piece supports are used to separate flexible piping runs at all +�x. crossover intersections, providing sufficientF support to prevent the upper pipe from deforming the lower pipe. 5.0 INSTALLER TOOLS OPW-FCS offers a variety of Installer tools for installing OPW-FCS's flexible piping system. NOTE: To insure proper installation `^ and product warranty coverage, only OPW-FCS pipe coupling equipment and pipe fabricating tools must be used. F 37 OPW FUELING CONTAINMENT SYSTEMS 5.1 Pipe Cutter The FlexWorks pipe cutter is designed to produce a clean and even pipe cut which is necessary for proper coupling attachment. 5.2 Jacket Cutter This stripping tool is used to strip off a section of the secondary jacket on the outside of the double wall piping. This is required for installation of swivel pipe couplings. NOTE: When using coax pipe couplings, do not strip the secondary jacket of the pipe. 5.3 Coupling Machine The FlexWorks Coupling Machine is required for the installation of both coax and swivel pipe �x gauge or a valve stem (not included). Test couplings. This electrically -driven hydraulic caps are used to test the integrity of each machine is designed to internally expand the 5.5.1 Coax Test Caps -- - — metal pipe insert installed at the end of a Coax test caps are available to test flexible pipe section. Coupling machines are to coax fittings. Both the primary pipe and available in both 110 and 220 volt models. secondary jacket of the double wall pipe Consult your local OPW-FCS distributor for availability for rental or purchase of the coupling machines. Remote coupling machines are also available. lessen the possibility of damage. 5.4 Swivel Wrench This open ended wrench is sized to fit the swivel nut of the swivel pipe coupling. It is used to tighten the swivel nut on a metallic fitting, adapter or connector. NOTE: When installing swivel couplings, I i hand tighten the coupling onto the OPW-FCS fitting until it is snug. With an OPW-FCS Swivel Wrench, tighten the coupling nut 1/4 turn more or to 200 in/lbs. Do not allow the pipe to rotate during tightening. This procedure will prevent over tightening of the coupling past the maximum 200 in/lbs. 5.5 Test Caps These custom threaded plugs have a 1/4" NPT port in the end for attachment of an air gauge or a valve stem (not included). Test caps are used to test the integrity of each pipe section prior to installation. 5.5.1 Coax Test Caps -- - — Coax test caps are available to test 1-1/2" and 2" pipe sizes and attach to coax fittings. Both the primary pipe and secondary jacket of the double wall pipe section can be tested with the coax test cap.
