The second application for coax elbow fittings Is to connect two sections of flexible piping fitted with coax couplings, This is useful when a sharp 90" degree tum is required. IV 3.1.7 Coax Riser Pipe Adapter These adapters contain a female pipe thread on one side and a custom coaxial male face w/0 -rings to accept coax fitting at the opposite end. These adapters are used with coax tee fittings and coax elbow fittings where interfacing with a standard threaded riser pipe or flex connector required. 3.1.8 Coax Riser Kit The coax riser kit Is used when Isolation of a partial length of the riser pipe is required. The kit consists of a coax riser pipe adapter, coax riser adapter, two riser pipe nuts, coax riser plug w/0 -rings, seals and a 36" length of coax riser jacket. The coax riser jacket is a UL listed, nonmetallic stand-off jacket that provides isolation from the environment as well as interstitial space for monitoring. 3.1.9 Coax Shear Valve Kit The coax shear valve kit Is used when the isolation of the full length riser pipe is required in a direct burial application. The frit consists of a coax riser adapter, coax shear valve adapter, two riser pipe nuts, one extra long riser adapter nut, coax riser plug w/0 -rings, seals and a 36" length of coax riser jacket. 'rhe coax riser jacket Is a UL listed, nonmetallic stand- off jacket that provides isolation from ground environment as well as interstitial space for monitoring. 2" male NPT base -threaded shear valves such as those available through OPW-FCS, are required for the coax shear valve kit. 5.6 Test Gauge Assembly This air gage assembly provides a means of testing only the interstitial space of double wall piping. These gauges connect to the end of the test tubes and have a maximum pressure PAGE 13/30 ,F/OWVORKS PT DPW "Ut"NO CtlN'?4R?R 'tPrr 07A712MIl 3,2 swivel Couplings & FlWngs Swivel couplings & fittings are of a single wall design and are used to interconnect OPW-FCS's flexible piping, These UI-® listed stainless steel couplings and fittings may not be directly buried and must be installed within containment sumps, Double wall piping requires the use of rubber test boots to seal -off the interstitial space of double wall flexible piping. For flexible double wall piping applications which are routed in series, the metallic junction tees should be fitted with connector tubes to permit the interstitial space of the piping to bypass the single wall coupling and fitting, Swivel fittings are standard in NPT threads. The metallic couplings & fitting components are available in 3/4", 1, 1-1/2", 2" and 3" sizes and are illustrated below. 3.2,1 swivel Pipe Couplings (SPC Series) Available only in single wall design for attachment to OPW-FCS's piping, these metallic couplings fasten to the end of a flexible pipe section using the FlexWorksNO Coupling Machine, Each coupling assembly includes a stainless steel insert, stainless steel ferrule, stainless steel swivel nut and flat Viton gasket, Swivel couplings require a different face plate to be used with the FlexWorks Coupling Machine than is used with coax couplings. 3.2.2 Double Wall Swivel Pipe Couplings (DPC Series) Double Wali Swivel couplings and fittings are of a double wall design and are used to interconnect FlexWorks flexible piping. 711`11`� These UU ULC listed stainless steelcouplings must be contained within containment sumps and not directly buried. The pipe connection system includes an internally expanded stainless steel coupling attached to the end of a FlexWorks pipe section. The swivel coupling has a smooth sealing face fitted with a viton ring gasket rouble wall Swivel Couplings eliminate the need for cutting back the secondary jacket and rubber test boots. They have an integral interstitial access port for connector and test tubes, Please see FlexWorks publication DPC-0001, Installation instructions for Double Wall Coupffngs (DPC) and Test Tubes (17T and TCT).
