s <br />The GeoFlex Piping System <br />Environ Products Inc offers an environmentally safe, flexible, underground <br />piping system. The GeoFlex Piping System provides continuous piping runs <br />between underground storage tanks and the product dispensers making <br />connections only within conlalnment sumps which are accessible from the surface <br />GeoFlex Pipe <br />There are two types of flexible pipe <br />constructions available for use in direct burial <br />underground piping applications of hazardous <br />liquids. GeoFlex I is recommended for use with <br />hydrocarbon fuels only. GeoFlex 11 is <br />recommended for both hydrocarbon and alcohol <br />based liquid fuels. Both flexible pipe designs <br />have a smooth inner bore, enhancing hydraulic <br />flow efficiency and providing an excellent <br />sealing surface for the metallic couplings. <br />GeoFlex Piping is available in continuous rolls <br />and packaged in easy to handle protective <br />cartons and reels. Currently available are 1-1/2" <br />• <br />for routine inspection and future maintenance. This complete system includes <br />flexible piping and fittings, tank sumps, dispenser sumps, pipe entry seals and <br />leak detection. The system components are compatible with most fuels and <br />chemicals and are designed for direct burial and rigid conduit applications. <br />and 2' pipe sizes with a variety of other sizes <br />available in the near future. GeoFlex Piping <br />offers a unique coaxial design, having both the <br />inner primary supply pipe and an outer <br />secondary containment pipe all in one. The <br />secondary containment jacket is separated by <br />stand-off ribs creating a small interstitial space <br />which allows for optimum flow and has excellent <br />burial strength. This coaxial design permits <br />Installation of a continuous -Liquid Interstitial <br />Monitoring System" and makes periodic integrity <br />air testing simple. <br />Pressure Piping Systems <br />GeoFlex Pipe may be used for pressure systems <br />which typically use a submersible pump Installed at <br />the tank. This manual further explains pump/piping <br />connections, piping junctions and pipe routing designs <br />for these types of piping systems. <br />Suction Piping Systems <br />GeoFlex Pipe may be used for suction systems which <br />typically use a suction pump located in the product <br />dispenser. This manual further explains suction <br />Pump/piping connections, tank transitions and pipe <br />routing designs for these types of piping systems. <br />Index <br />Introduction ............................................. <br />1 <br />Dispenser Containment Sumps. ...... <br />11 <br />Piping System Information ....... .... <br />... 2 <br />Dispenser Sump Specifications............... <br />12 <br />Guide Specifications ...... ...._................... <br />2 <br />Flexible Mounting Frames............... <br />12 <br />Piping System Components .................... <br />3,4 <br />Dispenser Sump Mounting ....................... <br />13 <br />Installer Tools . ................................... <br />..... 5 <br />Other Containment Sumps...................... <br />13 <br />Piping System Design ............................. <br />6 <br />Pipe & Conduit Entries............................. <br />14 <br />Pressure Systems Routing ..................... <br />6 <br />Tank Sump Plumbing Connections.......... <br />15 <br />Piping Design Tools 8 Services ............... <br />7 <br />Manifold Sump Plumbing Connections.... <br />16 <br />Suction Systems Routing ......................... <br />7 <br />In -Line Sump Plumbing Connections....... <br />16 <br />Pipe Burial Requirements ........................ <br />8 <br />Layout/Design Assistance........................ <br />16 <br />Tank Containment Sumps ....................... <br />9 <br />Dispenser Sump Plumbing Connections. <br />17 <br />Tank Sump Mounting Applications.......... <br />10 <br />Flexible Pipe Measuring ........................... <br />18 <br />General Information <br />This product manual contains useful <br />Information about the GeoFlex Piping <br />System. Therefore it is recommended <br />that this manual be read prior to system <br />specification and installation. <br />All installing contractors shall be trained <br />and certified by a factory representative <br />on the proper installation procedures. <br />Contact Environ Products Inc for more <br />Information on the Installer certification <br />program. <br />Only Environ manufactured coupling <br />equipment and Installer tools shall be <br />used to Insure proper installation and <br />warranty coverage. <br />Only Environ pipe couplings, fittings, <br />adapters and seals shall be connected <br />to the GeoFlex Piping. Conventional <br />pipe and fittings are permitted for pump <br />plumbing trees, tank fitting transition and <br />dispenser riser pipes. <br />This manual also contains GeoFlex <br />Piping warranty information (see back <br />cover) which shall go Into effect only if <br />the installation and Integrity testing <br />procedures are Performed In accordance <br />with this manual. <br />To <br />Cutting Flexible Pipe .... ,_, 19 <br />Coupling <br />Coupling Flexible Pipe ............................. <br />19 <br />Installing Flexible Pipe Sections .............. <br />20 <br />Flexible Pipe Connections ....................... <br />21 <br />Interconnecting Test Boots ...................... <br />21 <br />Testing 6 Filling Supply Pipe ................... <br />22 <br />Periodic Line Leak Detection Testing...... <br />22 <br />Interstitial Integrity Testing ....................... <br />23 <br />Penodic Interstitial Testing 8 Maint.......... <br />23 <br />GeoFlex Piping System Leak Detection.. <br />24 <br />GeoFlex Continuous Monitoring System. <br />24 <br />Glossary......... ........................ .................. <br />25 <br />Warranty.................................................. <br />26 <br />'i.
