Corrosion Monitoring in insulated Pipelines


Present techniques for corrosion monitoring in insulated pipelines. The pipelines with heat insulation can be affected by corrosion caused by different dilations and temperatures at which the pipelines and their respective layers of insulating material are exposed throughout the days. This difference between the expansions and the difference in environmental temperature may cause the appearance of condensation (appearance of moisture) between the wall of the pipeline and the layers of insulating material. This moisture starts the corrosion process of the outer wall of the duct that normally cannot be visually monitored. The main objective of this paper is to present innovative techniques for monitoring corrosion as is occurring so that you can schedule maintenance of these pipelines will occur before a leak fluid at high temperature which can have serious consequences for the plant or for people.
