External Coating

External Coating

Corrosion under insulation occurs at an accelerated rate and can remain undetected for some time. Taking affected parts of the pipework out of service for repairs or replacement can in turn lead to high costs and lengthy downtime. To address this problem, heat activated composites and coatings that facilitate online repairs. These materials adhere exceptionally well to hot contaminated surfaces and penetrate deep into the substrate eliminating the need for an angular blast profile priorto application.

Simple manual surface preparation and on-line brush application have inspired the use of heat activated materials to combat CUI globally, from the Gulf of Mexico to the North Sea. Typical applications in the range of -10°C to 150°C (50°F - 302°F) will resist salt spray and commonly found inorganic acids and alkalis at concentrations up to 20%.

Insulation can then be sealed with a breathable membrane to prevent further liquid permeation. membrane can be easily cut open for localised inspection and resealed with little impact on the process.
