Controlling Corrosion

摘要

Ajoint U.K.and Norwegian consortium has spent three years working together to develop a completely new solution based on Electrical Impedance Spectroscopy(EIS) that provides a solution for one of the biggest global challenges facing the oil and gas sector: the non-invasive detection of corrosion under insulation(CUI).With this system,there is absolutely no need to remove the outer cladding or underlying insulation,and there is only a need for a single access point to a long continuous pipeline,which means it can very easily be retrofitted onto aging assets.Other advantages are that: 1.It scans very long lengths of insulated pipeline in seconds;2.The sensor network can become a SCADA system and operable from a single location or control center;and 3.It will detect both sudden catastrophic leaks and gradual long-term changes as CUI progresses in very large,distributed pipeline networks.
