What is the most common reason
why a water heater fails?
Failureofatank’sprotectiveliningallows
watertocomeintodirectcontactwiththe
steeltankcausingittocorrodeandleak.
Therefore,thetypeofprotectiveliningis
thesinglemostimportantfeaturewhen
determiningthequalityofanywaterheater.
Theabilityofaliningtoprotectthesteeltank
isprimarilybaseduponitsthicknessand
completecoverageofallsteelsurfaces.
Linings Available For A Steel Tank
Cement Lining
AspeciallyformulatedHydrastonecement
appliedtoaminimumof
5
/8"thicknessonall
surfaces.Thecementliningcovers100%of
allinteriorsurfacesandis125timesthicker
thanglasslining.Duetothethicknessand
guaranteedcoverageofcementliningthereis
noneedforasacricialanode.Anextremely
durableandlonglastingliningsuitableforhot
andcoldpotablewaterstorageinavarietyof
commercialandindustrialapplications.
Phenolic Lining
Anepoxycoatingappliedin2coatstoatotal
of10-12milsDFT.Typicallyusedinprocess
applicationsusinglowconductivityDI,distilled,
orfoodgradewater.
Non-Ferrous Tanks
A solid Non-Ferrous tank does not require a lining becausethepressurevesselitselfis
constructedfrommaterialwhichisimpervioustothecorrosiveeffectsofhotwater.Thistypeoftank
willprovideasignicantlylongerservicelifethanalllinedsteeltanks,butisinitiallymorecostly.
90/10 Copper-Nickel
A90%Copper10%Nickelalloyprovides
excellentstrengthandcorrosionresistance.
Typicallyusedinapplicationswithcorrosive
environments(saltwater)orincriticalmarine
applicationsrequiringlongtanklife.
Stainless Steel
StainlessSteel(Specify:Type304,316,or
316L)issuitedforapplicationsrequiringa
corrosionresistanttankwithminimalleaching
ofimpuritiesintothewater.Wellsuitedfor
