Pulsed Eddy Current Array (PECA) and Rope Access Gear

Corrosion under insulation (CUI), a damage mechanism commonly found on insulated equipment such as pressure vessels, storage tanks or piping, can be a challenge to detect and properly assess. This is especially true when it is not possible or desirable to remove the insulation of a component or when the component is only partially accessible.

In such cases, asset owners may choose to perform visual inspection exclusively without insulation removal, since they are not aware of alternative solutions, which can lead to critical items being missed. However, Nucleom can help bridge the gap for the inspection of multiple types of insulated components by combining the latest inspection technologies with innovative solutions.

Nucleom recently performed the inspection of a fully insulated 30 ft. high vertical pressure vessel, only accessible from ground level, using Pulsed Eddy Current Array (PECA) and rope access gear. The result was full-corrosion mapping of the vessel on nearly 100% of its surface without removing any insulation.

If you have been told that you need to fully strip the insulation of a critical component or set up extensive scaffolding, give us a call before doing so – we can help you find innovative solutions to reduce operational cost and downtime, and give you better confidence in your CUI inspection program.
