These tests include measuring the material's retention of physical properties and determining the capability of the compound to withstand exposure. 1.5 Corrosion Resistance All metal framework components are either powder coated, galvanized or zinc plated for excellent long term corrosion protection. The entry seal fasteners are made of stainless steel All of these metallic components are accessible from inside the sump. The sump body is non-metallic and will never corrode. 2.0 SPECIFYING DISPENSER CONTAINMENT OPW-FCS offers a wide variety of under dispenser containers to accommodate the most common types and sizes of product dispensers. The selection of the appropriate type of under dispenser container depends on the following: 2.1 Junction Applications Dispenser containers used in junction applications occur only in pressure piping systems with series pipe routing (from one dispenser to the next). This �— application uses the tee fitting to interconnect one flexible pipe section to the next, as well as branching off vertically to the fuel dispenser. 2.2: Terminating Applications Dispenser containers used in terminating applications are typically at the end of pressure piping systems with series routed piping. They are located under all dispensers of suction piping systems with direct routed piping. They are also located under all dispensers of pressure piping systems with branch routed piping. This application uses the elbow fitting attached to a riser pipe assembly to attach one flexible pipe section to the fuel dispenser. -'* 2.3 Dispenser Containment Models Five types of dispenser containers are available for use MN the FlexWorks piping system. They include: 2.3.1 One Piece Sumps These higher profile dispenser sumps have a total height of 30 inches permitting the FlexWorks pipe to exit out of the dispenser sump at a very low elevation which is ideal for pressure piping systems requiring slope back indirectly to the tank. They are also recommended for use with pressure piping systems run in series which require piping fall back to the tank. These dispenser sumps are height adjustable to accommodate piping fall requirements between all containment sumps. These are available in poly for most dispenser models, and in fiberglass for a few dispensers. See the FlexWorks Dispenser Directory in the FlexWorks Product Catalog for availability. 2.3.2 Two Piece Polyethylene and Fiberglass Sumps These higher profile dispenser sumps have total height of 37 inches permitting the FlexWorks pipe to exit out of the dispenser sump at a very low elevation which is ideal for pressure piping systems requiring slope back indirectly to the tank. They are also recommended for use with pressure piping systems run in series which require piping fall back to the tank. These dispenser sumps are height adjustable to accommodate piping fall requirements between all containment sumps. Because of its two piece design, connection of all fittings is easier than in standard one piece dispenser sumps. 3.0 DISPENSER MOUNTING FRAMES Ak6 All dispenser containment models share the same type of metal frame assembly. The frame assembly is specifically sized to accommodate one or more types of makes and models of product dispensers. All metal side struts, which secure the adjustable stabilizer bars, are directly anchored into the concrete using side ENVIC IONMENTAL HEA, T�_, DEc� PTMENT
