6 Piping system layout <br />(cont'd.) <br />Fig. 6-4. Use flexible connectors to <br />connect fiberglass pipe to tanks, <br />turbine outlets at tanks and to shear <br />valves at dispensers. A4 -ft. minimum <br />length of fiberglass pipe (dogleg) is <br />allowable per API Specification 1615 in <br />lieu of a flexible connector. <br />Fig. 6-5 <br />a) Typical sump penetration detail for a <br />system piped in parallel or at last sump <br />of system piped in series. <br />b) Typical sump penetration detail fora <br />system piped in series and utilizing <br />termination tees. Allows pressure <br />rating on secondary of 75 psi. <br />Note: Standard tee with a termination <br />nut and a reducer bushing. <br />c) Typical sump penetration detail for a <br />system piped in series and tested at <br />lowpressure. <br />Note: 24 -inch minimum width <br />recommended on dispenser sumps to <br />facilitate series installations. <br />�IO <br />J <br />Bell x male NPT adapter Dog leg (4 ft min) <br />Slope to tank Single wall fiberglass <br />vapor recovery line <br />.

This variation results from: <br />• Manufacturing tolerances in the bell <br />• Differences in length of tapers prepared on the job site <br />• Difference of insertion depth when dry fit and after adhesive has been applied. <br />Flexible sump penetration fitting installation <br />• Measure to the appropriate height for the center of the hole, making sure to allow <br />for the desired slope for the piping in the station layout. <br />• Mark the height across sump. <br />• Measure and mark the location of each penetration on the line, on the flat panel. <br />• Using a 5 -inch hole saw for dispensers, 6 -inch for tanks, cut a hole for the <br />penetration fitting. <br />• Sand and clean the edges to create a smooth surface to properly seat the <br />fitting in the sump wall.
