0 System components Fig. 1. Dualoy 30001FLX it end connectors make up to standard NPT threaded fittings. Connectors have been designed to provide approximately 1 inch of axial travel to facilitate thread make-up. Fig. 2. A Dualoy 30001FLX It 90° sweep elbow joined to two lengths of Dualoy 30001L rigid -wall containment pipe with push -on containment couplings. Ninety degree and 45° sweep elbows are available with 36 -inch bending radius. Fig. 3, Duafoy 30001FLX 11 couplings are used to join 3 -inch rigid -wail pipe to construct the outer containment piping. No adhesive is required for assembly: pipe and couplings effect a fluid -tight seat by means of 0 -rings (1). The left side of the illustration shows a length of pipe (2) already inserted into the coupling (3); the right side shows pipe (4) and coupling prior to assembly. The coupling features a pipe stop (5) in the middle to prevent overinsertion of the containment pipe. in actuality, the entire containment system would be assembled before the primary line (6) is introduced. Fig. 4. Dispenserpans should beat least 24 inches wide to Permit easy access while installing the piping components. Wall penetrations are made using flexible penetration seals or Ameron penetration fittings. FLEXIBLE PIPING Dualoy 3000/FLX ll 11/2 -inch (I D) primary piping is delivered to the job site in coils of 500 feet. End connectors are swaged onto the primary piping at the job site. Once in piace, the end connectors are capable of both circumferential and axial movement for easier installation and make-up. The length of the end connectors figures into the calculation of the overall length forany given run of pipe. RIGID -WALL PIPE AND FITTINGS Dualoy 3000/1 - rigid -wall pipe and fittings are used to contain Dualoy 30{)0/FLX II flexible, primary piping and in single-wall vent and vapor recovery lines.'; Rigid -wall piping materials include the foliowing: • Three-inch Dualoy 3000/1- rigid -wall fiberglass pipe for containment piping. • Three-inch 90° or 450 sweep containment elbows, • Three-inch containment couplings with O-ring seal. • Two-inch Dualoy 3000/1- rigid -wall fiberglass pipe, tees, elbows and threaded adapters for vent and vapor recovery lines. DISPENSER PANS Ameron recommends that fiberglass dispenser pans be used. if the dispenser pan is fabricated of a non - fiberglass material such as steel or high-density polyethylene, contact Ameron regarding appropriate methods for making and sealing penetrations. The make and model number of the dispenser crust be known before ordering the dispenser pan. The critical dimension for the dispenser pan is the width, which should amount to at least 24 inches 24 to provide easy access during installation (Fig. 4). The depth of the dispenser pan may vary depending on the
