Corrosion Under Insulation (C.U.I.)
Corrosion under insulation (C.U.I.) has long been an underestimated problem. Water ingress, leaking products (often corrosive, flammable or toxic) and weather conditions, can lead to major damage to the insulation and underlying pipes or installations. Effective corrosion prevention prevents costly repairs, a production stop and dangerous situations. Our corrosion prevention products are designed to protect your plant and people.

What is corrosion under insulation?
Insulation is used in the industry to prevent unwanted cold and heat transfer. In addition, insulated pipes protect against skin injuries. When an insulation system is not functioning optimally, corrosion under insulation can occur. CUI often occurs on insulated pipes and equipment at service temperatures from 0°C to 175°C., because the locations where CUI occurs are difficult to detect and it also depends on several factors, it is a difficult phenomenon to predict and control.
What risks does CUI pose?
CUI poses a wide range of risks that can cause serious consequences and even casualties. In fact, CUI occurs under the insulation and is therefore considered a hidden defect. Corrosion can often run its course undisturbed in the process industry, and is sometimes called a silent killer. To observe corrosion under insulation, it is important to perform regular inspections and maintenance on the facilities. Corrosion prevention, or the timely detection of corrosion, is necessary to ensure the following:
-
Employee safety and protection
Addressing corrosion under insulation proactively can ensure employee safety and prevent potential hazards. Identifying and treating corrosion problems ensures that employees are not exposed to hot, toxic or corrosive fluids.
-
Continuous production process
By addressing corrosion under insulation in a timely manner, unwanted breakdowns and prolonged production interruptions can be avoided. Inspecting and maintaining pipes and equipment prevents cracks and bursts, resulting in smooth and uninterrupted production. This promotes process efficiency and minimizes costs associated with production losses.
-
Optimization of energy performance
By properly applying insulation and preventing corrosion, energy loss can be minimized and energy efficiency improved. Properly functioning insulation ensures effective heat transfer, reducing the amount of energy needed to support the process. This leads not only to cost savings, but also to a more sustainable and environmentally friendly working environment.
Corrosion under insulation products
Though corrosion prevention is important from the issues mentioned above andt because corrosion is located under insulation, it is difficult to detect. Places where water can collect, so-called critical locations, make the most sense to start inspecting. With CUI, 80% of corrosion is in logical locations and 20% is in illogical locations.
Temati has a range of products for preventing and detecting corrosion and ensuring the safety of processes and personnel. In this regard, coatings are an essential element in combating CUI. Flange protectors increase safety by preventing moisture or hazardous products from becoming trapped under insulation and enable efficient leak detection. Inspection plugs make visual inspection under insulation easy, and Temati drain plugs drain water or moisture efficiently.
