Corrosion under insulation (CUI) is a longtime plague of petrochemical, refinery, and marine environments. The problem is so bad that an estimated 40 - 60% of piping maintenance costs in the oil and gas industry stem from CUI-related expenses. Even worse, undetected CUI on pipes carrying hazardous liquids may lead to leaks and potential explosions. To tackle this dangerous and costly problem, Cortec® Corporation has developed CorroLogic® CUI Inhibitor Injection, a new vapour phase Corrosion Inhibitor technology that simplifies protection for insulated pipes reaching a high range of temperatures.
How to prevent corrosion under insulation
CorroLogic CUI Inhibitor Injection is a new high-temperature 100% vapour phase Corrosion Inhibitor (VCI/VpCI®) for protection against CUI. As its name implies, CorroLogic CUI Inhibitor Injection can be injected directly into insulating material. The corrosion inhibiting vapour migrates from the injection point along the pipe to form a hydrophobic protective layer on metal surfaces beneath the insulation. This passive layer is long-lasting, protects in the presence of chloride-containing moisture, and can withstand high temperatures up to 662 °F (350 °C).
Advantages of CorroLogic CUI Inhibitor injection
CorroLogic CUI Inhibitor Injection offers an incredible advantage over other methods of CUI protection that can only be applied after removing insulation or before insulating new pipes. Maintenance personnel now have the convenience of applying protection under existing insulation, even on surfaces that reach high temperatures. This results in a wider timeframe in which to apply preventative measures, increasing the chances of inhibiting and arresting corrosion before it gets too serious.
