1 Introduction Dualoy 3000/LCX primary pipe and fittings are manufactured from thermosetting epoxy resins reinforced with high tensile strength fiberglass filaments.The pipe is produced by filament winding.The pipe incorporates a resin-rich inner liner that is resilient and holiday-free and a resin-rich outer coating that protects the structural wall from UV degradation during storage and installation.The structural wall strength of Dualoy 3000/LCX pipe is unsurpassed in the fiberglass pipe industry.Primary fittings are manufactured by filament-winding or compression molding. Dualoy 3000/LCX pipe and fittings are electrically non-conductive and never require cathodic protection or sacrificial anodes.Installed systems are immune to external corrosion from stray-current electrolysis and cathodic interference.They are unaffected by alkaline or acidic soil conditions. The primary pipe and fittings are joined using the same strong,reliable bonded joint as in Dualoy 3000/L single wall piping. The primary and containment piping systems are completely separated,making this a true coaxial system.The space between the primary and containment pipe is controlled by an even layer of graded sand.Precise dimensions are maintained as is a free-flowing interstitial space. The containment connection between the pipe and fittings is made by a fast,effective mechanical seal with elastomeric gaskets. Dualoy 3000/L single-wall piping systems Detailed installation instructions for Dualoy 3000/L single-wall piping may be found in Ameron Bulletin 7501 (FP104)available from Ameron Fiberglass Pipe Group or your Ameron distributor. 2 Listings and Dualoy 3000/LCX is Listed in the United States with Underwriters Laboratories for approvals nonmetallic underground piping for petroleum products,alcohols and alcohol-gasoline mixtures(File MH9162).Dualoy 3000/LCX pipe&fittings are also listed with Underwriters ULp Underwriters Laboratories of Canada for Petroleum Products and Oxygenated Fuels(File CMH715). 11r/ laboratories Inca 3 Inspection, handling Inspection and storage Careful inspection of the outer(secondary)layer of pipe is especially important on coaxial containment installations.Since damage to the primary is not visible once the pipe is installed,it is essential to check the outer pipe jacket for damage.Testing has shown that no damage will occur to the primary pipe without an indication of damage on the outer jacket. Upon receipt at the job site,inspect the pipe fully.Locate,cut out,repair or replace damaged pipe.Impact damage is usually recognizable as rounded pale areas just under the surface or as deep gouges,scratches or cracks.Remove end protectors to inspect tapers for damage and then replace protectors.Inspect grooves and threads on fitting assemblies for damage.If threads are badly damaged or grooves are affected,discard and replace with a new part. Handling Dualoy 3000/LCX has the higher impact resistance than single-wall pipe,however, fiberglass pipe is susceptible to damage if handled improperly.Adhere to the following recommendations when handling: • Do not transport pipe without proper protection against impact. • Truck pipe racks should be padded with carpeting or like material to prevent damage. • Tie the pipe down during transport to prevent it from bouncing on the racks. • Do not use chains to tie down the pipe on a truck:Use nylon straps or hemp rope. • Do not drop the pipe from truck bed when stringing:Lay the pipe down by hand. • Pipe loads that are properly separated and supported can be unloaded by padded forklifts. Storage Dualoy 3000/LCX pipe incorporates a 5-mil thick,resin-rich reinforced outer coating which provides outstanding UV resistance.Pipe stored out-of-doors for extended periods may assume a chalky appearance.However,this change in appearance is superficial and does not affect the pipe's performance.Protect stored pipe from impact damage by stacking on padded racks.
