Abstract

Fiberoptisk ledningsrør til anvendelse i et aggressivt miljø innbefattende et aksielt rør. Det aksielle røret omfatter et korrosjonsbestandig materiale og kan motta en eller flere optiske fibrer. Det fiberoptiske ledningsrøret innbefatter videre et hydrogenbarriereskall som er anbrakt i kontakt med det aksielle røret. Hydrogenbarriereskallet omfatter et materiale som er i stand til å redusere hydrogenpermeabiliteten gjennom det fiberoptiske ledningsrøret og har en tykkelse på minst omtrent 0,0254 mm.
