Composite Industrial Group, Inc. has protected new heat exchangers from the factory and those that have been in service for many years. We apply two (2) coats of 100% solids ceramic epoxy at a total film thickness of 20-30 mils. This barrier coating is applied to the entire tubesheet, both end covers and the water box to prevent any further bimetallic corrosion. This repair solution is proven to last for a lifetime and Composite Industrial Group, Inc. is pleased to offer a Lifetime Limited Warranty for their heat exchanger work. Please contact Composite Industrial Group, Inc. for more details on this program.
Practically all commercial and industrial facilities have heat exchangers and the majority of them are rusting away behind the scenes. The design of these units includes a steel end plate with copper pipes used in a heat transfer process. The use of dissimilar metals in an immersion situation is proven to cause bimetallic corrosion, a situation that will severely corrode the steel plate and cause serious problems over time if left untreated.
