What is a major cause of heat exchanger failure?

A major cause of heat exchanger failure is indeed corrosion or fouling from improper maintenance. Over time, heat exchangers can accumulate deposits from the fluids that pass through them, which may come from natural contaminants, chemical reactions, or other sources. This accumulation can significantly impede the heat transfer efficiency of the exchanger, leading to overheating, reduced performance, and ultimately mechanical failure.

Additionally, corrosion can occur due to the interaction of fluids with the materials used in the heat exchanger. If maintenance is not performed regularly or correctly, the protective measures that could prevent corrosion may not be applied or may be insufficient, exacerbating the issue.

Regular cleaning and inspections are crucial to maintaining the integrity and functionality of heat exchangers, ensuring that any fouling or corrosion is addressed before it leads to significant operational failure. Understanding the importance of proper maintenance helps in preventing such issues that could lead to costly repairs or replacements.
