PVI Industries designed the AquaPLEX hot water storage vessel, which eliminates the need for tank linings. This tank is a blend of austenitic and ferritic steels that combine grain structures to make it highly resistant to various types of corrosion, higher in tensile and yield strength than carbon steel, and typically 15% less in weight than a polymer- or nickel-lined water heater. A passive layer of protection is formed when the high chromium content combines with the oxygen, resulting in virtually no material loss or corrosion when the tank is exposed to the dissolved oxygen or other aggressive agents found in potable waters.
