Description
Corrosion under insulation (CUI) is one of the costliest and unavoidable problems facing the hydrocarbon processing industry today. CUI affects the steel piping, storage tanks, container vessels and other process equipment within the plants that are subject to extreme temperature fluctuations.
Insulation applied to the pipe can mitigate the thermal cycling effects. But the presence of seams, gaps or other discontinuities in the protective cladding or in the insulation layer makes them susceptible to infiltration by outside humidity or from the process environment itself.
The CUI industrial IoT sensor is tailored to continuously monitor wetting on insulated assets such as piping systems or vessels, as a part of a cost-efficient Corrosion Under Insulation (CUI) risk prediction system. Measurements are automatically transmitted to the CirruSense CUI cloud platform for further storage, analysis and presentation. The solution enables optimized maintenance based on actual corrosion risk.
With use of the CUI sensor you can pay attention to most critial parts of the pipeline, as well as reduce HSE risk for the physical worker in the hazardous area. Inspection in dry areas can be avoided or postponed. This will give you the oppurtunity to go from a reactive maintainance plan to a preventive and predictive method, which will also be cost saving over time.
