Four Best NDT Methods for Corrosion under Thermal Insulation Four Best NDT Methods for Corrosion under Thermal Insulation – many literatures and data have proved that Cui is a very common and complicated phenomenon, and it is very difficult to find this kind of corrosion, and it needs a lot of time and economic cost. The corrosion under insulation layer is the corrosion phenomenon of pipeline or equipment covered by insulation layer due to the entry of water and corrosive substances. This corrosion is usually hard to detect because it is usually hidden under an insulating layer, traditionally detected by: Remove pipe surface coverings; Check the pipes; Restore the original appearance of the surface coverings. This process involves a lot of cost and logistical issues. Even cutting the cladding alone is a very time-consuming and labour-intensive process, which may be further complicated if the covering material contains asbestos and needs […]
