Under insulation corrosion(CUI)was a corrosion phenomenon caused by the infiltration of water or other corrosive media into the insulation layer,which formed an electrolyte environment with the metal surface.CUI had the characteristics of concealment,wide range,and great harm.Using the Tabi digital ray measurement method to measure the wall thickness of insulated pipelines,combined with high and low ray energy and image processing technology,the measurement accuracy for CUI was improved,meeting the needs of on-site inspection and detection.
