SearchMETRALOOP EXPANSION JOINTSMetraloop expansion joints forseismic applicationsA safe, cost-effective seismic expansion joint.Piping used in applications and locations subject to seismic conditionshave their own set of unexpected random movements and greater costs toovercome. There is a solution – the ultra-flexible Metraloop.The random motion common to earthquakes requires that seismicexpansion joints be capable of movement in any direction. Of the 6possible directions, Metraloop sees axial movement of the hose in only twoof them – compared to four in an "L" shaped assembly. Metraloop'sorientation can be changed relative to the piping, further minimizing thelikelihood of compressive movement.Find the Metraloop end fittings and sizesyou need for your application?Select your end fittingTemperature Correction FactorsMetraloop OptionsPressure Drop (Friction Loss) ChartsMetraloop offers significant cost and safety benefits not found incomparable seismic expansion joints.zIt is an inexpensive alternative to dual-tied bellows expansion joints andespecially ball joints.zDuring an earthquake, it protects equipment by allowing boilers, chillers,fan-coil units and other systems to move independently of the building.zMetraloops installed at the connection also prevent nozzles fromcracking or shearing off.zAnd the AGA-certified Metraloops, installed in gas lines as they crossthe building's seismic joints or at the connection to gas-fired equipment,protect against fire and the devastation that results.Typical installations of Metraloops for seismic service are shown in thefigures above. For more detailed installation instructions for seismicapplications, refer to the NUSIG (National Uniform, Seismic InstallationGuidelines) book.To assure operation in seismic applications, the Metraloop expansion loophas been accepted for use by the California Office of Statewide Health,Planning and Development and the City of Los Angeles; and certified bythe American Gas Association.There's no limit to the seismic applications that Metraloop can handle. Itcan even be designed with lined hose for high velocity, double-braid forhigh pressures, and all stainless steel construction for media compatibility.TopSWEAT ENDSCopper sweat ends with bronze hose & braid(† See Temp Correction Factor)Show your pipes a little love duringthermal expansion and contractionMetraloop expansion joints exert a fractionof the anchor loads, requires fewer pipeguides, and takes less space.Metraloop vs traditionalmethods to compensate forthermal and seismicexpansionGo configure!See just a few of the crazy ways toconfigure the Metraloop expansionjoint
