Cortec® Promotes Injection-Based Alternative for Easier CUI Prevention in O&G Operations

March 19, 2026

Cortec^® Corporation applauds the continued development of advanced monitoring and inspection technologies for preventing CUI and supports their broader adoption across the industry. At the same time, Cortec^® recognizes that financial limitations and practical challenges to accessing high-risk insulated surfaces remain significant barriers to preventative maintenance ideals. To help mitigate these obstacles, Cortec^® encourages O&G maintenance teams to consider the benefits of two CorroLogic^™ corrosion inhibiting technologies that can be injected into insulation without the costly, invasive removal and replacement of existing materials.

CorroLogic^™ CUI Inhibitor is a solvent-based Vapor phase Corrosion Inhibitor formula that can be injected into existing insulation on piping, tanks, pipelines, and other equipment that reaches operating temperatures as high as 338 °F (170 °C).

CorroLogic^™ CUI Inhibitor Injection is a biobased Vapor phase Corrosion Inhibitor formula (contains 100% USDA certified biobased content) that can be injected into insulation on metal piping and systems operating at temperatures upwards of 600 °F (316 °C).* Both CUI inhibitors are designed to migrate to insulated metal surfaces and form a protective molecular barrier against moisture, condensation, and other corrosive elements. Key advantages include the following:

• Apply without removing insulation
• Protect metals undergoing wet/dry cycles and temperature cycling
• Use on offline or operating system
• Inhibit corrosion in the presence of chlorides

As Eric Uutala, Technical Sales Manager of CorroLogic^™ technologies, explains, “Removing insulation can be cost prohibitive and may interrupt process operations. Injecting CorroLogic^™ CUI through the insulation provides immediate corrosion protection, while allowing for operations to continue as normal.”

While CorroLogic^™ CUI inhibitors enable maintenance teams to protect unseen surfaces with limited inspection, they also make excellent companions to precise inspection tools, allowing facilities to closely monitor the effect of treatment and build a data set to support their maintenance budget.
