Composite Tank Repair – What Type Of Repairs Are Possible?

Explore the versatile repair solutions offered by our team, tailored to address a range of issues from minor defects to extensive corrosion. Our approach to tank repair extends from applying structural patches over small, localized areas, such as three-wall defects, to undertaking comprehensive wraps of entire shell courses—especially critical at the liquid line where oxygen-induced corrosion is prevalent. Adhering to strict code compliance, we ensure each repair, regardless of scale, avoids the critical 12-inch zone at the tank’s base. While external repairs offer a flexible solution for varying tank problems, it’s important to note their effectiveness may be curtailed by internal corrosion, impacting the longevity of the repair. Discover how we balance scalability and precision to meet the unique needs of each tank, ensuring optimal outcomes. 

We can do an external repair that can be over a small, localized area. So if you have a three-wall defect the rest of the steel around, it’s good, you can simply put on a structural patch that also requires calculations and the same approach, but it’s limited in scope and size. We can also do an entire show course. So usually at the liquid mine, we encounter a lot of corrosion due to the oxygen and how that liquid is behaving. So, you know, we may have an entire course that we end up wrapping, or we can do a an entire wrap. If it’s, you know, strictly code compliant, we’re staying out of the 12 inch critical zone at the bottom. We talked about the scalability of the repair, we can go from very small to very big depending on the actual needs or problems in the tank. Now the disadvantage of an external repair is that if you have internal corrosion, you’re going to have a limited life of that repair.
