CORROSION OF CHLORINE CONDENSER STUDIED BY ICT
氯气冷凝器腐蚀的ICT研究

The corrosion of tubes and tube sheets for a chlorine gas condenser in a chemical plant was studied using industrial computer tomography(ICT).ICT can not only detect whether are there gaps or interstices,but also quantitatively describe their size,shape and position.The ICT scan results indicated that the joint zone of the condenser baffle,condenser tubes and the welds are the sites suffered from serious corrosion damage.The condenser baffle in the side of brine presents a honeycombed surface and the pitting corrosion in the side of chlorine is much serious than that in the side of brine.ICT can effectively evaluate the corrosion of materials.
