In underground fuel systems, Dualoy 30001L <br />fiberglass pipe and fittings give <br />you • • no other product <br />(including steel). <br />Dualoy 3000/L from Ameron is the <br />best UL -listed piping available for <br />underground fuel system <br />construction and rehabilitation. <br />Manufactured from chemically inert <br />materials, Dualoy 3000/L fiberglass <br />pipe and fittings resist external <br />corrosion far better than cathodically <br />protected steel. <br />The Dualoy 3000/L liner delivers <br />features and performance no other <br />UL -listed piping system can offer. <br />Resilient and holiday -free, the flexible <br />inner liner is an added layer of <br />protection inside the structural pipe <br />wall. Competitive fiberglass pipe has <br />no liner. <br />Galvanized steel pipe can descale <br />when exposed to modern no -lead <br />fuels. The inert Dualoy 3000/L liner <br />remains intact throughout the service <br />life of the system, protecting <br />downstream strainers and pumps <br />while maintaining product purity. <br />Lightweight and easy to handle, <br />Dualoy 3000/L with its simple, <br />Thousands of steel service station fuel - <br />handling systems throughout the <br />United States have reached the end <br />of their service lifetimes. An API survey <br />has shown that unprotected steel tanks <br />and piping account for 94 percent of all <br />leaks, and nearly one-third of these <br />leaks can be traced to the piping itself. <br />Federal laws passed in 1984 and 1988 <br />permit only two piping materials for <br />service station rehabilitation and new <br />construction: catholically protected <br />steel or fiberglass. <br />Dualoy 3000/L provides secondary containment piping in a tank complex designed to store a <br />variety of jet fuels. Seen here is the inner carrier piping during initial layout. <br />threadless adhesive joint can be <br />installed in less than half the time <br />needed for steel. The result is <br />lower initial installed cost and a <br />maintenance -free corrosion resistant <br />piping system with a service life <br />much longer than steel. <br />Inert to external corrosion <br />Dualoy 3000/L piping is electrically <br />nonconductive and never requires <br />cathodic protection. Installed <br />systems are immune to external <br />corrosion from stray -current <br />electrolysis and cathodic inter- <br />ference. They are unaffected by <br />alkaline or acidic soil conditions. <br />Installation, inspection and <br />maintenance of costly impressed - <br />current systems and sacrificial <br />anodes are permanently eliminated. <br />Excellent flow <br />characteristics <br />The superior flow characteristics <br />of fiberglass pipe are now more <br />important than ever because of the <br />high pressure drop through today's <br />multiple product dispensers. <br />Because of its smooth inner liner, <br />Dualoy 3000/L maintains a high <br />Hazen -Williams coefficient of 150 <br />throughout its service life for <br />consistently low pressure drop. <br />11 <br />
