Cement Lined Tanks ProvideLonger Service Life
Q ?Failureofatank'sprotective liningallowswatertocomeintodirectcontactwiththesteeltankcausingittocorrodeandleak.
Therefore,thetypeofprotectiveliningisthesinglemostimportantfeaturewhendeterminingthequalityofanywaterheater.Theabilityofaliningtoprotectthesteeltankisprimarilybaseduponitsthicknessandcompletecoverageofallsteelsurfaces.
What is the most common reason why a water heater fails?
A !
■ ThicknessEachHubbellModelEstoragetankislinedwithaminimumof1/2"thickHydrastonecementtoensureprotectionofthesteeltank.
■ CoverageTheHydrastonecementliningcoversaguaranteed100%ofallinteriortanksurfacesandisfreefromflawsorimperfections.FullcoverageisachievedbyinjectingthepreciseamountofHydrastonecementintoeachtankandthencentrifugallyspinningitat250RPMtoensurecompleteanduniformcoverageoftheliningonallinteriorsurfaces.
■ Corrosion ResistanceHydrastonecementisaspecificallyformulatedhighdensityliningdesignedtoprovidemaximumprotectionfromthecorrosiveeffectsofhotwater.
■ Reduced Operating CostsTheHubbellModelEwaterheatersignificantlyreducesthetotalownershipcostofawaterheaterduetothelongerlifeandmaintenance-freebenefitsderivedfromaHydrastonecementlinedtank.LongertanklifeisdirectlyattributabletotheunmatchedtankprotectionprovidedbytheHydrastonecementliningandcopper-silicontappings.Additionally,theModelEreducesoperatingexpensesbyeliminatingtheperiodicinspectionandreplacementcostsassociatedwithmaintainingasacrificialanodeinaglasslinedtank.
