Maximizing The Life Of Spiral Wound Gaskets – Storage, Handling, And Failure Prevention

1. MaximizingTheLifeOfSpiralWoundGaskets– Storage,Handling,AndFailurePrevention • Spiralwoundgasketsrankamongthemostdependablesealingsolutionsutilizedinvariousindustries, includingoilandgas,chemicalprocessing,powergeneration,andmarineapplications.Engineeredfor durability,flexibility,andresistancetoextremetemperaturesandpressures,thesegasketsarecraftedto functioneffectivelyindemandingenvironments.Nevertheless,eventhesturdiestgasketcanexperience prematurefailureifnotstored,handled,ormaintainedcorrectly.Inthisarticle,weexploretwovital componentsofspiralwoundgasketperformance–appropriate storage andhandling techniques,along with anin-depthexaminationofgasketfailureanalysis–toassistyouinmaximizingtheutilityofyourgaskets whileminimizingthechancesofleaks,operationaldowntime,andsafetyrisks. • Theimportanceofstorageandhandling • Thecorrectstorageandhandlingof spiral woundgasketsarecrucial for maintainingtheir performance and extendingtheirlifespan.Thesegasketsaremeticulouslyengineeredwithprecisetolerancesandmaterials thatcandeterioratewhenexposedtomoisture,sunlight,dust,ormechanicalstress.Evenpriortoinstallation, inadequateinventorymanagement–suchasimproperstacking,temperaturevariations,orcontactwith contaminants–canjeopardizethegasket’sstructuralintegrity.Warpedmetalwindings,degradedfiller materials,orcorrosionmaynotalwaysbeapparentbutcanresultinsignificantsealingfailuresduring operation.Byensuringoptimalstorageconditionsandexercisingcarefulhandling,youguaranteethatthe gasketoperatesreliablywhenitis most needed. • Bestpracticesforstoringspiralwoundgaskets • Controltemperatureand humidity • Spiralwoundgaskets,particularlythosecontainingnon-metallicfillerssuchasgraphiteorPTFE,are vulnerabletoenvironmentalconditions.Elevatedhumiditylevelscanresultinoxidationorcorrosionofthe metalwindings,whileextremetemperaturesmaycompromisetheintegrityofthefillermaterials.Store gasketsinacool,dry,andshadedarea,preferablywithinaclimate-controlledfacilitythatoffersadequate ventilation.Steerclearoflocations closetoheatsourcesorareaspronetomoisture.

2. AvoidUVandchemicalexposure • Directexposuretosunlight,ozone,andairbornechemicals(includingsolventsorcleaningagents)cancause materialdegradation,particularlyinPTFEorrubber-coatedcomponents.Ensurethatthegasketsarekept coveredandsealedinprotectivepackaginguntiltheyareneeded.Avoidstoringthemnearvolatilechemicals orinenvironmentswithhighozonelevels,suchasnearoperatingmotorsorwelding stations. • Labeland rotateinventory • Gasketsmayappearthesamebutcanhavevaryingmaterialcompositionsorpressure-temperatureratings. Nottrackingusagedatescanresultintheinstallationofexpiredordegradedgaskets.Clearlylabelallgaskets withtheirmaterial,pressureclass,size,andmanufacturingdate.AdheretoFIFO(First-In-First-Out) principlesto preventinventoryfromagingexcessively. • Useverticalhangingracksorflatshelving • Improperstackingcanresultindistortion,warping,ordelaminationofspiralwoundgaskets.Placingheavy gasketsontopofoneanothercandeformthesealingsurfaceorunevenlycompressthefillerlayers.Store large-diametergasketsverticallyusinghangingracksorhorizontallyonflat,paddedshelves.Refrainfrom stackingmorethana fewunitstogether, especiallyiftheyareunboxed. • Handle with cleanhandsandtools • Contaminantslikeoil,dust,orparticlesintroducedduringhandlingcanjeopardizegasketintegrity.Improper handlingcanalsocausedentsorbendsinmetalliccomponents,diminishingsealingperformance.Utilize cleanglovesandtoolsduringinspectionandhandling.Refrainfromdraggingorslidinggasketsacross uncleansurfaces.Exercisecaution,particularlyduringtransportfromthewarehousetothe site. • Earlysignsofgasketdamagein storage • Evenincontrolledsettings,regularinspectioniscrucial.Lookoutfor– • Rustordiscolorationon windings • Delaminationoffillermaterial • Warpingordistortionofthegasketshape • Contaminationsuchasdust,oil,orchemicalresidue • Disposeoffanygasketthatseemscompromised.Usingadamagedgasketposesariskoffailure,evenunder standardoperational conditions. • Commoncausesofspiralwoundgasketfailure • Whileinadequate storage can shorten gasketlifespan priorto installation, numerousfailureshappen during oraftertheinstallationprocess.Graspingthesefailuremechanismsisessentialforenhancingsystem reliability. • Incorrectgasketselection • Choosingagasketmadefrominappropriatematerialsorwithunsuitablepressure-temperatureratingscan resultinswiftfailure.Forinstance,employingacarbonsteelwindinginacorrosivefluidenvironment,or utilizingagraphitefillerwhenPTFEisnecessaryforchemicalresistance.Verifycompatibilitywith operatingconditions–temperature,pressure,andmedia–byconsultinggasketdatasheetsorseekingadvice fromthemanufacturer.
