In underground fuel fiberglass pipe you something and • systems, Dualoy 3000/L fittings give no other product has (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 can offer. 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 API 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. Federal laws passed in 1984 and 1988 permit only two piping materials for service station rehabilitation and new construction: cathodically protected steel or fiberglass. Dualoy 3000/L provides secondary containment piping in a tank complex designed to store a vanety of jet fuels. Seen here is the inner carrierpiping 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. • • • • u Easy to transport and handle 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. 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 inert 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 standard UL -listed adhesive cures at normal temperatures without heating blankets or outside heat sources. 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 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 failures can be attributed to loose fittings. A worker easily carnes 100 feet of 2 -inch Dualoy 3000/L pipe during a service station rehabili- tation. 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 3000/L in 3 days than a three-man steel crew in 4 days. Full range of UL -listed sizes Dualoy 3000/L is the only line of fiberglass pipe, fittings and adapters available in a full two- 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. Secondary containment systems Ameron Dualoy 3000/L secondary containment systems use rigid, heavy -wall outer fittings with the next larger size pipe to enclose the carrier pipe totally from turbine to dispenser. These systems provide a continuous L annular space between secondary and primary which makes it possible to test the integrity of the containment and to monitor the product lines at any time. All pipe and fittings in an Ameron containment system are manufac- tured from the same fiberglass reinforced resins as the primary, so the containment piping has the same excellent chemical resistance as the product lines. Dualoy 3000/L containment systems are easy to install. The pipe is so smooth on the outside that the contractor need only remove the surface gloss at the ends of the pipe before installing the containment fittings: no special end preparation is required. Only Ameron can offer such simple installation. Complete inspectability Ameron Inspection Containment piping employs pipe of two slightly different diameters in the secondary Adjacent lengths of Inspection Containment pipe may be nested together to provide easy access to primary pipe and fittings. so that adjacent sections can be nested together, thus providing complete access to the primary line during bonding, testing and inspection. No other containment system is easier to install. After the primary has passed inspection, sections of Inspection Containment piping are joined with reducing couplings. UL -listed alcohol piping systems Ameron was the first in the fiberglass pipe industry to obtain UL listing for alcohol service in underground piping systems. Standard Dualoy 3000/L is compatible with allowable limits of alcohols (4.75% methanol; 10% ethanol) and ethers (15% MTBE). Ameron also offers a full range of fittings and adhesives which can be used with standard Dualoy 3000/L pipe for systems carrying alcohol blends and straight alcohols such as M85 and M100. 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.
