Introduction Thermalpipelinesarewidelyusedinvariousindustrialapplications,suchasoilandgas,chemicalprocesses,andpowergeneration.Thesepipesareusedtotransportfluidsathightemperatureandpressure,andanyleakcanresultinseriousenvironmental,safety,andfinancialconsequences.Traditionalmethodsofleakdetectioninthermalpipelinesrelyonpressureortemperaturesensors,whichareoftenlimitedbytheirsensitivityandaccuracy.Thesemethodsarealsoinefficient,astheyrequireasignificantamountoftimetoaccuratelydetectthelocationandsizeoftheleak. Toovercometheselimitations,researchershaveproposedtheuseoffiber-opticsensorsforleakdetectioninthermalpipelines.Fiber-opticsensorsarehighlysensitive,accurate,andcandetectleaksinreal-time.Afiber-opticsensorconsistsofafiber-opticcablewithasensorelementatoneendandadetectorattheotherend.Thesensorelementisdesignedtochangeitsopticalpropertieswhenexposedtoaphysicalparameter,suchastemperature,pressure,orstrain.Thechangeintheopticalpropertiesisthendetectedbythedetector,whichsendsasignaltoadataacquisitionsystemforanalysis.
