Investigation of the corrosion under insulation behavior and chemical changes of various configurations of high temperature (> 260°C) thermally insulated systems and with and without deployment of novel Mica Spacer system
Corrosion under insulation (CUI) is a prominent damage mechanism in the hydrocarbon industries which results in the leaks and even lead to catastrophes. There are numerous spacer systems developed till date including Integrity Product’s Novel PTFE spacer wrap and Novel Insulation Ventilation system (IVS) which are studied comprehensively via Mitacs funded projects. All these spacer systems are effective for the pipes operating till 260°C due to the inherent limitation of PTFE and PVC (used for IVS) as these materials soften and hence loose their effectiveness above this temperature. Today. there is a huge network of pipelines, facility piping and equipment that operate at high temperatures (i.e., > 260°C) and run the risk of thermal degradation of the insulations via binder burnout, voids formation, moisture absorption and eventual CUI. So the use of PTFE and PVC wraps for such applications is not suitable. So there is a need to study the systems that can survice high temperatures to mitigate the CUI and SCC risks.
