----Piping-System---Procisiorr-pipe-exterk)r-eliminateT-scarf]nT---Dualoy pipeIs manu ac ure In a proprietary continuous <br /> Characteristics winding process that provides an extremely precise,consistent outside diameter. Light sanding of the pipe <br /> end to remove the surface gloss and obtain a suitable bonding surface is the only end prep required,although <br /> the scarfing feature of tapering tools can be used. <br /> Easy containment fitting assembly—Dualoy 3000/L containment fitting clamshells are supplied in matched <br /> pairs.One half of each pair is fitted with pre-inserted propeller nuts,allowing the fitting to be assembled from <br /> one side, using the bolts provided. <br /> Complete retestability—Dualoy 3000/1-containment employs rigid-wall pipe and fittings that maintain their <br /> slope during the entire service life of the station.When installed with isolating penetration fittings (see page <br /> 3),Dualoy 3000/L containment piping can be repeatedly retested whenever desired. <br /> Convenient repair capability— Contained piping systems are occasionally damaged after installation. <br /> Damage is generally caused by paving or excavation operations. Dualoy3000/L contained piping systems <br /> are designed so that only the damaged section need be replaced instead of the entire line.The 2-inch Dualoy <br /> repair coupling is sized so that it can be contained within 4-inch Dualoy 3000/L containment pipe. <br /> Two-inch primary pipe con- <br /> tained within 3-inch contain. 4x3 inch reducing <br /> merit pipe can be repaired with couplings <br /> a UL-listed 2-inch repair cou- �/' 2tirth 2patrcoupling <br /> piing.
