Tank Linings and Corrosion

May 9, 2020 12:00 am Published by Leave your thoughts

Your industrial tanks can be corroded from the inside out—which is why it’s smart to paint the inside of your tanks or get a premade tank lining. Lining the inside of your tanks preserves their longevity and ensures a safe, bacteria-free environment for their contents. If you’re dealing with tank corrosion in Colorado, DJC Enterprises Inc. has a number of smart solutions for your business.

How corrosion occurs

When you store liquids—especially acidic liquids—within a tank, the likelihood of corrosion goes way up. The chemical reaction that occurs when liquids are stored within a tank eventually leads to corrosion over time, as both the liquid and the tank itself constantly readjust to their surroundings. This can result in corrosion as well as decay and abrasion—all of which have deleterious effects on your tank interior.

Types of tank linings

Here’s a closer look at some of the most common types of tank linings and how they stand up to corrosion:

  • Epoxy: Epoxy, which is also known as resin, is a hardened plastic coating that can help ward off unwanted effects like corrosion and decay. Bisphenol A and epoxy novolac are two of the types of hardening agents used in epoxy tank linings. Both of them create an extremely hard surface, consisting of a super-hardened three-dimensional surface. When the resin hardens, it cross-links chains of molecules and creates an impenetrable barrier for chemicals, liquids and other substances.
  • Fluoropolymers: The most recognizable type of fluoropolymer is Teflon—the same stuff that makes up your non-stick frying pan. The fluorines involved make up a nearly-impenetrable coating, which is impervious to chemicals of various types. If you store harsh chemicals and other highly abrasive contents, fluoropolymers might be a wise choice for your business.
  • Polyurethanes: Polyurethanes are reactive epoxies that are sensitive to humidity in the environment, which you can use to enhance its effects. The polymers react with the humidity in the environment to form chains of cross-linked polymers, which are very hard and quite versatile. Depending on how they’re applied, they can be rigid or soft and flexible, making them an excellent choice across many applications.

The most important thing to take away is that if you’re storing anything in a tank, it should be lined somehow. Not only does it make things cleaner and less prone to rot, corrosion and other issues, but it will extend the lifespan of your storage tanks and decrease downtime in your industry. In a world where time is money, this is a smart, easy solution to save you money much farther down the road.
