Introduction Dualoy 3000/1-pipe and fittings are manufactured from chemically inert thermosetting <br /> epoxy resins reinforced with high tensile strength fiberglass filaments.The pipe is <br /> produced by filament winding.The pipe incorporates a resin-rich inner liner that is <br /> resilient and holiday-free and a resin-rich outer coating that protects the resin-glass bond <br /> of the structural wall from UV radiation during storage and installation.The structural wall <br /> strength of Dualoy 3000/1-pipe is unsurpassed in the fiberglass pipe industry.Fittings <br /> are manufactured by filament-winding or compression molding:injection molding is not <br /> employed. <br /> Dualoy 3000/1-pipe and fittings are electrically nonconductive and never require <br /> cathodic protection or sacrificial anodes.Installed systems are immune to external <br /> corrosion from stray-current electrolysis and cathodic interference.They are unaffected <br /> by alkaline or acidic soil conditions. <br /> O <br /> Listings and approvals Dualoy 3000/1-is Listed in the United States with Underwriters Laboratories Inc.(UL)for <br /> nonmetallic underground piping for motor vehicle fuels(MV),concentrated fuels(CF), <br /> high blend fuels(HB)and aviation and marine fuels(AM).It is also Listed with <br /> Underwriters Laboratories Canada(ULC)for the same fuel categories. It can be used <br /> o Underwriters for primary carrier(PC),normal vent(NV)and vapor recovery(VR)under UL File No. <br /> U L Laboratories Inc.® ULC` MH 9172.It can be used for secondary containment(SC)under UL File No.MH 15596. <br /> The ULC File Number is CMH 715. <br /> Inspection,handling Inspection <br /> and storage <br /> Upon receipt at the jobsite,inspectthe pipe fully.Locate,cutout,repair or replace <br /> damaged pipe.Impact damage is usually recognizable as rounded pale areas just <br /> under the surface or as deep gouges,scratches or cracks.Remove end protectors to <br /> inspect tapers for damage and then replace protectors. <br /> Handling <br /> Fiberglass pipe is susceptible to damage if handled improperly.Adhere to the following <br /> recommendations when handling: <br /> • Do not transport pipe without proper protection against impact. <br /> • Truck pipe racks should be padded with carpeting,inner tubes,or the like to <br /> prevent damage. <br /> • Tie the pipe down during transport to prevent it from bouncing on the racks and <br /> suffering impact damage. <br /> • Do not use chains to be down the pipe on a truck:Use nylon straps or hemp rope. <br /> 3 <br />
