5 Key Takeaways from Webinar – CUI Test Results: Understanding the Corrosive Mechanism

Last week, we hosted CUI Test Results: Understanding the Corrosive Mechanism, a live webinar detailing the latest test results from the most recent long-term corrosion under insulation (CUI) testing. Our webinar covered the various types of corrosion, the science behind the thermodynamics of corrosion, and the latest findings from long-term corrosion research on Thermo-1200™ calcium silicate, and Sproule WR-1200® expanded perlite, and a silica aerogel blanket specimen. If you missed the webinar, don’t worry. Below, we’ve outlined 5 takeaways from the webinar, and you can watch a recording of it here on the Webinars tab. There is a growing trend in…

5 Ways to Avoid Galvanic Corrosion

Galvanic corrosion (also called bimetallic corrosion) is a deteriorative electrochemical process that occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte. This type of corrosion is characterized by the accelerated corrosion of one metal, while the other remains mostly unaffected. In other words, one metal becomes the anode and corrodes preferentially, thus sacrificing itself while protecting the other metal, the cathode. Galvanic corrosion is relatively aggressive and causes millions of dollars in damage annually. Countermeasures to prevent its formation must be taken into consideration at the conceptual or early stages of the…

Corrosion Under Insulation: The Challenge and Need for Insulation

When it comes to corrosion under insulation (CUI), I tend to call it a "minefield," and for more than one reason. It’s not only a hidden phenomenon, but it's also one that can really come back to bite companies who don’t invest in a good CUI mitigation strategy, because sooner or later, those companies are going to get their names in the papers due to unwanted accidents, production loss and environmental damages.  But when the proverbial horse has bolted, a lot of asset owners want to close the stable doors by implementing rigorous measures. The problem is that they often…

Advancements in CUI Detection & Overview of MsS Guided Wave

Guided Wave Ultrasonic Testing (GUL), or Long Range Ultrasonic Testing (LRUT), is considered a viable screening approach for detecting CUI related problems in the oil and gas industry. Guided wave ultrasonic testing is a nondestructive inspection method in which low-frequency omnidirectional ultrasonic waves propagate along internal geometric boundaries, in order to detect corrosion. As the guided waves travel across the confined boundaries, the waves will then be reflected at areas with cross-sectional changes, identifying areas with corrosion. These low-frequency waves are able to travel great distances with less sound attenuation. Not only can GUL provide expeditious and expansive coverage, it…
