The major source of fouling deposits is the coolant/process fluid proper.   Water-based fluids often transport and deposit a wide variety of minerals throughout the system.  Additionally, corrosion products often form as a consequence of reactions that occur between the process fluid and the various system materials.

Essentially all of the commercial chemical cleaning agents that are commonly used to dissolve inorganic deposits and corrosion products are also corrosive to many construction materials.   For this reason, a post-cleaning component/system passivation treatment is often required to restore corrosion resistance.  Passivation is a separate chemical process that is thought to form a very thin, corrosion resistant, oxide coating on cleaned component/system surfaces.

Corrosion Resolutions furnishes or reviews component/system mechanical or chemical cleaning and passivation procedures. The key elements of our service are the provision of:   a) engineering assurance of the adequacy of the selected cleaning method; b) procedural specifications of appropriate QC tests; and c) citation of exactly defined acceptance criteria that are necessary to verify that the desired results will be obtained. We also confirm that unintended adverse system results will not occur, e.g. by chemical cleaning of piping systems with a process method that is effective in cleaning the piping, but also promotes excessive downstream heat exchanger tube corrosion or failure.

Carbon steel, cast iron and stainless steel system materials are often found to contain highly corrosive oxides that visually appear to be harmless. These detrimental oxides are produced during component fabrication, specifically during heat treatment, welding, etc.   They are also produced during field welding. Corrosion Resolutions ascertains whether or not these corrosive oxides are present and assures that they will be completely removed, if so.
