Corrosion Under Insulation

Corrosion Under Insulation (CUI) is a common problem in process industries and makes up a large percentage of maintenance expenditure. CUI is any type of corrosion that occurs due to a moisture build-up on the external surface of insulated equipment or assets.

The Danger of Corrosion Under Insulation

CUI is most commonly galvanic, chloride, acidic, or alkaline corrosion. The damage can occur in equipment operating at ambient, low and heated services, depending on conditions and in equipment that is in or out of service.

If undetected, the results of CUI can lead to the shutdown of a process unit or an entire facility, and in rare cases it may lead to a process safety incident.

Detecting CUI

Detecting Corrosion Under Insulation usually means removing insulation to conduct an inspection. TesTex NDT use the latest Pulse Eddy Current Technology (PECT) to offer the highest quality testing of corrosion in insulated pipelines and vessels.

PECT technology has been designed with a specific embedded software to facilitate the process of creating an inspection set-up, conducting the examination and generating the associated report.

The result is improved scan speed and resolution with multiple readings across the surface providing an overall map of the area. This means inspections can take place without the need to remove insulation and can even locate weld locations underneath the lagging.
