Exploring the Mechanism and Longevity of Corrosion Inhibitors in Insulation

Thermal insulation is an integral part of the petrochemical and refining industry used to conserve energy, maintain process control, and ensure operator safety. It is a key component to ensuring industrial operations run as efficiently and sustainably as possible. Insulation systems, comprised of thermal insulation, jacketing, mastics, and sealants, are designed to keep water out in order to maintain the integrity of the thermal insulation and limit corrosion under insulation (CUI).

However, even the best designed and installed systems sometimes become compromised, resulting in the presence of water at the pipe surface and the potential for CUI. As such, it is important to understand how the chemistry of the thermal insulation affects the CUI potential. Read more.
