Sensors for Detecting Corrosion Under Insulation

Rohrback Cosasco released three types of Cosasco corrosion under insulation (CUI) corrosion sensors for detecting corrosion under insulation: continuous insulated braid “corrosion fuse” wire (Type 1), inserted “corrosion fuse” probe array (Type 2), and the CUI Corrosometer Probe (Type 3). The three techniques offer direct corrosion detection and a much lower cost per monitoring point than existing methods and may be customized to meet individual requirements and applications to fit with any plant integrity management program. The sensors offer savings on inspection and repair costs plus simple and low-cost installation (Types 2 & 3 do not require removal of insulation). (
