Engineers, by nature, are proactive in their quest to improve the processes, systems, and designs that they work on daily. But, looming deadlines and budget constraints often mean that you make insulation choices without added consideration. Are you choosing insulation because it’s what was already in place and that’s good enough for now? We’re not knocking that approach; we get it. However, if you’re looking for long term solutions for problems that plague your insulation systems—including CUI— we think it’s time to ratchet up your proactive ways and make a different choice. So, let’s talk about that.
Corrosion under insulation can only occur in a wet environment. The implication of wetness on insulation selection is well summarized in section 220.127.116.11 of NACE Standard SP0198 Control of Corrosion Under Thermal Insulation and Fireproofing Materials:
“Because CUI is a product of wet metal exposure duration, the insulation system that holds the least amount of water and dries most quickly should result in the least amount of corrosion damage to equipment.”
In both hot and cold service, non-wicking, non-absorbent insulation is often the preferred material choice. No one wants their insulation to get wet—wet insulation is truly one of industry's contradictions. Yet, today, many facilities continue to use outdated, water-absorbing insulation, putting their processes and profitability at risk, and their assets and risk for CUI.
It’s a conundrum, for sure. But Pyrogel offers something that proactive engineers are relying on more and more.
