Abstract

Denne fremgangsmåte og anordning påviser potensialet for korrosjon i rør som har vegger fremstilt i ledende material (14) innleiret i ikke-ledende material, idet det ledende material (14) er inneklemt mellom en indre (10) og ytre (12) foring, og som skyldes kontakt mellom et ledende medium fremmed for røret og det ledende material (14) innleiret inne i rørveggen. Det elektriske potensial mellom det fremmede medium og rørets ledende material (14) bestemmes. Potensialets stabilitet konstateres og dersom potensialet ikke varierer utover et forutbestemt område i løpet av en tidsperiode, bedøm- mes potensialet til å være stabilt og derved angi elektrisk kontakt mellom det fremmede medium og det ledende material (14) inne i røret, hvilket fremmer korrosjon. En ustabil spenning angir manglende elektrisk kontakt.
