Water by its very nature is designed to dissolve materials that it contacts. This includes metals. Perforation of metal because of corrosion can occur and does occur in almost all metals.
The causes of corrosion are well known. The wide variety of corrosion patterns and processes is less well known. The science of metallurgy has shed some light on this topic. A complete and thorough failure analysis is needed to expose the fundamental issues leading to the failure.
Other kinds of leaks that do not necessarily involve corrosion are the simple passing of machine water through a seal, mechanical or otherwise. This too involves examining materials of construction and water chemistry.
Water Management Services Inc. will has personnel trained in corrosion and failure analysis.
