The new VpCI® technology of Cortec simplifies protection for insulated pipes reaching a high range of temperatures.
In order to tackle the dangerous and costly corrosion under insulation (CUI) in the oil and gas industry, Cortec Corporation has developed CorroLogic® CUI Inhibitor Injection, a new Vapor phase Corrosion Inhibitor® technology that simplifies protection for insulated pipes reaching a high range of temperatures.
The corrosion under insulation happens when moisture and other corrosive media enter insulation after water barrier wraps or jackets are compromised or when condensation builds up, often unnoticed, beneath the insulation. The threat is potentially greater on offshore platforms or in other marine environments with chloride-rich sea and with piping that undergoes wet-dry or high-low temperature cycling. Even worse, undetected CUI on pipes carrying hazardous liquids may lead to leaks and potential explosions.
CorroLogic CUI Inhibitor is a new high-temperature 100% VpCI that can be injected directly into insulating material. The corrosion inhibiting vapor migrates along the pipe to form a hydrophobic long-lasting protective layer on the metal surfaces that can withstand temperatures up to 350° C.
Once piping is installed and insulation is in place, it is difficult to see and correct the problems that may be going on beneath the surface. The new solution developed by Cortec allows a wider timeframe in which to apply preventative measures, increasing the chances of inhibiting and arresting corrosion. CorroLogic® CUI Inhibitor Injection helps pipes last longer and reduces cumbersome repairs on insulated surfaces. In addition, it also minimises the risk for corrosion-related failures, increasing overall plant safety while reducing maintenance costs.
