0 � 7 In underground fuel systems, Du fiberglass pipe and fittings give you something no other product (including steel). Dualoy 3000/L from Ameron is the best UL -listed piping available for underground fuel system construction and rehabilitation. Manufactured from chemically inert materials, Dualoy 3000/L fiberglass pipe and fittings resist external corrosion far better than cathodically protected steel. The Dualoy 3000/L liner delivers features and performance no other UL -listed piping system has. Resilient and holiday -free, the flexible inner liner is an added layer of protection inside the structural pipe wall. Competitive fiberglass pipe has no liner. Galvanized steel pipe can descale when exposed to modern no -lead fuels. The inert Dualoy 3000/L liner remains intact throughout the service life of the system, protecting downstream strainers and pumps while maintaining product purity. Lightweight and easy to handle, Dualoy 3000/L with its simple, Thousands of steel service station fuel -handling systems throughout the United States have reached the end of their service lifetimes. An APl survey has shown that unprotected steel tanks and piping account for 94 percent of all leaks, and nearly one-third of these leaks can be traced to the piping itself. The Federal Tank Law of 1984 permits only two materials for service station rehabilitation and new construction: cathodically protected steel or fiberglass. cloy 30001L • has Dualoy 3000/L provides secondary containment piping in a tank complex designed to store a variety of jet fuels. Seen here is the inner carrier piping during initial layout threadless adhesive joint can be installed in less than half the time needed for steel. The result is lower initial installed cost and a maintenance -free corrosion resistant piping system with a service life much longer than steel. Inert to external corrosion Dualoy 3000/L piping is electrically nonconductive and never requires cathodic protection. Installed systems are immune to external corrosion from stray -current electrolysis and cathodic inter- ference. They are unaffected by alkaline or acidic soil conditions. Installation, inspection and maintenance of costly impressed - current systems and sacrificial anodes are permanently eliminated. Excellent flow characteristics The superior flow characteristics of fiberglass pipe are now more important than ever because of the high pressure drop through today's multiple product dispensers. Because of its smooth inner liner, Dualoy 3000/L maintains a high Hazen -Williams coefficient of 150 throughout its service life for consistently low pressure drop. • • Easy to transport and handle IS The light weight of fiberglass makes Dualoy 3000/L easier to transport and handle than steel. A typical service station requires from 800 to 1000 feet of piping. For 2 -inch steel pipe, that's about 13/4 tons—a hefty truckload. The same footage of Dualoy 3000/L weighs less than 500 pounds and can easily be carried on a light pick-up. One person can unload enough Dualoy 3000/L for a whole service station job quickly, by hand, without a forklift. The fiberglass pipe weight advantage is even more telling during installation. A standard 20 -foot length of 2 -inch steel weighs over 70 pounds, the equivalent Dualoy 3000/L a scant 9 pounds. This means easier handling and lower labor costs during cutting, end preparation, layout and joining. Rapid end preparation • Pipe end preparation is a large part of overall job cost. Dualoy 3000/L pipe arrives at the job -site with the ends factory tapered. Fiberglass pipe and nipples can be cut to length much more quickly than steel, and the cut ends tapered in a fraction of the time needed to thread steel pipe. For example, a 2 -inch end can be prepared in less than 20 seconds using a portable tapering tool for on-site joint preparation. Most steel pipe failures start at threaded joints: threading the pipe peels off the protective coating and exposes the bare metal. By contrast, the Dualoy 3000/L pipe wall is constructed of corrosion resistant materials throughout, so tapering the pipe end does not compromise its corrosion resistance. Simple, threadless joining Dualoy 3000/L employs a deep - socket bell and spigot adhesive joint • for faster joining than threaded steel • pipe. Matching tapers in bell and spigot make a firm interference fit to hold the joint together while the adhesive cures. Ameron's UL - listed adhesive cures at normal temperatures without heating blankets or outside heat sources. And for cold weather installations, the necessary accessories are readily available from Ameron. Unlike competitive fiberglass and steel piping, Dualoy 3000/L has no threads to cross or strip. A slight twist as the spigot is inserted into the bell and the joint is complete. The joint can usually be made by a A worker easily carries 100 feet oft -inch Dualoy 3000/L pipe during a service station rehabilitation. The same length of equivalent steel pipe would weigh over 350 pounds. Dualoy 3000/L pipe is so easy to work with that it can be cut to length using an ordinary hacksaw The cut end of the pipe is then tapered with a portable tapering machine Both cutting and tapering can be accomplished without even getting out of the trench. The quick adhesive joint is one reason a two- man crew can put in more Dualoy 30001L in 3 days than a three-man steel crew in 4 days. single worker. Compare this to the effort needed to screw steel pipe together, where it frequently takes two workers to join even 2 -inch pipe—to say nothing of larger sizes. An important point since 1 out of 7 steel pipe joint leaks can be attributed to loose fittings. Full range of UL -listed sizes Dualoy 3000/L is the only line of fiberglass pipe, fittings and adapters available in a full 2- through 6 -inch size range with Underwriters' Laboratories listing. Ameron thus offers UL -listed components not only for typical small -diameter service station installations, but also for large -volume facilities such as bulk fuel terminals, marinas and central fuel oil systems. u Resistant to sunlight In the final step of the unique Dualoy 3000/L pipe manufacturing process, a uniform resin -rich exterior coating is added to protect the resin - glass bond of the structural wall from UV radiation. As a result, Dualoy 3000/L can be stored out of doors without special precautions before installation. Secondary containment systems Ameron secondary containment systems use rigid, heavy wall outer fittings with the next larger size Dualoy 3000/L pipe to totally enclose the UL -listed carrier pipe from turbine to dispenser. These systems provide a continuous space between secondary and primary which makes it possible to test the integrity of the containment at any time. All pipe and fittings in a Dualoy 3000/L containment system are manufactured from fiberglass reinforced epoxy resins. As a result, all components 0 in the outer piping have the same excellent chemical resistance as the carrier line. Dualoy 3000/L containment systems are easy to install. Dualoy 3000/L pipe is so smooth on the outside that the contractor need only remove the surface gloss before installing the containment fittings: no special end preparation is required. Only Ameron can offer such simple installation. Sales and technical assistance Our engineering department provides technical assistance to owners and contractors in specifying, designing and installing underground fuel -handling systems. Dualoy 3000/L piping is available in the United States and Canada through the most extensive stocking distributor and sales representative network of any fiberglass pipe manufacturer. Contact Ameron Fiberglass Pipe Division, Houston, Texas for further information. Ameron secondary containment systems employ rigid, heavy wall epoxy fittings with Dualoy 3000/L pipe to contain the carrier piping.
