In the Growing Trend Toward Water-resistance, What Are My Insulating Options?

Corrosion under insulation (CUI) is a hot-button issue for the industrial industry, and rightfully so. Studies have shown that CUI is the cause of 40-60% of the money spent on piping maintenance in the oil and gas industry1. That’s no small sum, and that’s why many minds throughout the industry are working to find new solutions to help prevent or inhibit corrosion. This has often been done through finding methods to prevent water from contacting the surface of the pipe, like pipe coatings or water-resistant insulations. Water is frequently an integral component to pipe corrosion, thus inhibiting water contact can…

Mitigation of Corrosion Under Insulation (CUI) of Carbon Steel of Different Insulating Materials

Equipment often found in refineries may be enveloped in insulation and weathering jackets to maintain internal processing temperatures. In many cases moisture from the environment will penetrate the weathering jacket and infiltrate the insulation, leaching corrosive ions to the surface of metal equipment, effectively creating a corrosion cell. The goal of this project is to investigate different insulating materials for their ability to inhibit corrosion under insulation (CUI). The inhibiting mechanism utilizes water ingress that leaches ions from the insulator to bond with the surface metal and create a passive layer, inhibiting any further corrosion. This study will follow ASTM…

How to Detect and Prevent Corrosion Under Insulation in the Oil and Gas Industry

Corrosion under insulation (CUI) is one of the problems crippling the gas and oil industry. It can cost companies a lot of money every year in repair, inspections, and replacement costs. It refers to a form of corrosion that occurs between the material used for insulating gas lines and the outer surface of a pipeline. corrosion under insulation is the cause of most leaks experienced in the oil and gas industry. It is also one of the problems that companies in the gas and oil industry are struggling to address. Water will always seep into the insulating materials and eventually…

Stopping Corrosion Under Insulation in Global Oil and Gas Facilities

Corrosion under insulation (CUI) is the root cause of many of the global petrochemical industry’s most serious problems including forced shutdowns, lost production, early repair and replacement, as well as safety and environmental consequences that can cost millions of dollars per incident. CUI, which involves the corrosion of vessels or piping beneath insulation due to water penetration, is insidious because it can remain undetected until the insulation is removed for inspection or leaks occur. Water penetration can result from many causes including monsoons, rain, flooding, wash downs, and sprinkler systems, as well as exposure to steam, humidity or frequent condensation…

Keeping the Lights on During Extreme Cold Snaps

Polar vortexes. Hurricanes. Wildfires. With climate change making extreme weather events more frequent and intense, it is getting harder to keep the lights on and HVAC systems running. As a power system researcher, I believe utilities need to get better at withstanding disasters and the disruption they cause. Investing more heavily is key, especially in infrastructure upgrades, renewable energy and microgrids — small and self-sufficient sources of power that help consumers either stay off the grid by choice or simply stay connected during outages. Different kinds of weather can obstruct access to electricity. In extreme cold snaps, like the one that…
