CUI (Corrosion Under Insulation)
Corrosion Under Insulation is the term used to describe the situation when water penetrates externally clad or jacketed insulation causing the corrosion of steel piping, vessels and other assets. It is often a major cause of repair and maintenance work for asset owners.
Altrad Services is an expert in CUI technology: we have developed methodologies to assist our customers in identifying areas where CUI is likely to occur. And, as a state-of-the-art insulation and anticorrosion specialist, we have a wide experience in detecting the causes of water ingress into and the development of moisture under all types of insulation systems.
Our engineers often carry out thermographic inspections to detect CUI (without the assets having to be taken out of operation). In addition, during the initial engineering phase of asset development and in the planning of inspection routines, we evaluate the potential risks due to CUI and we design sustainable solutions to avoid its consequences in the long run.
However, once CUI is identified as an issue requiring our intervention, our site personnel execute all operations, from simple maintenance to complete insulation removal, steel repair/treatment and insulation replacement.
