We hope you took advantage of our lifetime limited warranty for rebuilding and coating your tube sheets over the winter. If you haven’t and you have some serious corrosion, there is still ample time to repair this equipment.

I was staring out the window thinking about my old welding school days and learning about all the different types of corrosion and how they affect different substrates.

So many types of Corrosion…. 

• General or Uniform Corrosion
• Crevice Corrosion
• Stress-Corrosion Cracking
• Galvanic Corrosion
• Pitting Corrosion
• Intergranular Corrosion
• Microbiologically-Influenced Corrosion (MIC) (Bugs) 

And the factors and mechanisms differ. 

Heat exchangers are susceptible to erosion damage and galvanic corrosion due to contact between the dissimilar metals. When we leave this damage untreated, the operational efficiency of the system will be seriously undermined with the potential for complete deterioration of components.  If the galvanic corrosion proceeds too long before it is addressed you can get a leak all the way through the tubesheet and the fluid on one side will mingle with the fluid on the other.   This may not be a huge deal if both are water but usually one is refrigerant which might not be very good for the atmosphere or it could be a harmful chemical that should never be leaked.  So, best case scenario is a huge loss of efficiency and capacity in the heat exchanger.  Worst case scenarios include the release of radioactive steam and or catastrophic EPA fines. 

Belzona has the right solution to protect these units.  Our products are electrical insulators and provide outstanding barrier properties so all those types of corrosion I’ve listed above are no longer an issue.  Your component equipment is protected for the long term and by that we mean 20, even 30 years and sometimes longer.  We even offer a lifetime limited warranty as discussed below. 

A local university built a new chiller plant and had us coat 6 brand new 60" diameter chillers.  The reasoning is that by protecting the substrate they will get a few more decades service from that equipment.  

Let us know how we can help you repair, protect and improve your component equipment.

Limited Lifetime Warranty

We have been applying protective coatings to chillers and heat exchangers for over 30 years. When specified and applied properly, these coatings give such reliable, trouble-free, and lengthy service lives that we have decided to offer a lifetime limited warranty
