Problem: Corrosion under Insulation (CUI)

CUI is a severe type of confined external corrosion occurring in insulated carbon and low alloy steel. This kind of corrosion occurs when moisture is absorbed by or collected in the insulation.

By the time, a pipeline owner/operator realizes they have a CUI issue it is usually too late. This is why selecting a suitable anti-corrosion coating or wraps at the onset is essential. For those with corrosion under insulation problems, Trenton Corporation came up with a creative solution.

Solution: High Temp HT 3000 Anti-Corrosion Wrap

The image shows a section of a pipeline that was identified with a corrosion concern. The owner protected the pipe with Trenton HT 3000 Anti-Corrosion Wrap by:

1. Removing the insulation from the localized affected area
2. Preparing the pipe to SP-2 Conditions by eliminating loose mill scale, rust, paint, and other disadvantageous foreign matter by hand chipping, scraping, sanding, and wire brushing
3. Applying the Trenton 3000 Primer
4. Wrapping the pipeline with HT3000 High-Temperature wrap

The Trenton product offers the operator a solution for corrosion under insulation that has ease of preparation and application and extends the length of service for the pipeline.
