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. JJ/ 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 - couplings. This electrically -driven hydraulic machine is designed to internally expand the metal pipe insert installed at the end of a flexible pipe section. Coupling machines are available in both 110 and 220 volt models. Consult your local OPW-FCS distributor for availability for rental or purchase of the coupling machines. Remote coupling machines are also available. IMPORTANT: Before and after the coupling process, the supplied dust cover should be kept on the couplings. This precaution will 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, 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.

These gauges connect to the end of the product dispensers. dispensers divided equally. the test tubes and have a maximum pressure rating of 15 psi. 5.7 Fishing Bullnose Attaches to the end of a flexible pipe section in order to fish (push or pull) the flexible pipe section through the Access Pipe. Its rounded nose provides an easy means of feeding the pipe through the Access Pipe. The swivel bullnoses are fitted with a metal eyelet for attachment of a plumber's fish. Available in 1-1/2" and 2" pipe sizes for attachment to both coax pipe couplings and metallic pipe couplings. 6.0 PRE -INSTALLATION PLANNING The type of pipe routing design selected is dependent on the quantity and orientation of the dispensers, the type of system (either pressure or suction) and the layout of the facility. One constant design requirement is that all piping that runs between containment sumps be continuous. Single and dual piping lines may be used depending on the total quantity of dispensers to be serviced and the location and orientation of the islands. The pipe routing design criteria for OPW-FCS's flexible piping system is considerably different than that of conventional rigid piping. For either new or retrofit installations, good pre -installation planning is a must to insure a proper installation. 6.1 Single Series Routing 6.2 Dual Series Routing This system is used in This system is used in .,pressure" systems where one "pressure" systems where two piping line interconnects all of piping lines interconnect all the the product dispensers. dispensers divided equally. 6.3 Direct Routing This system is used in "suction" systems where one piping line is directly connected to only one dispenser inlet. 7.0 PIPING DESIGN CRITERIA When designing and installing Flex piping systems, use the following criteria to insure that they meet OPW-FCS's requirements:
