NOTE
Circle (O) marks in the chart show the factor relevant to corrosion or water scale.
When the water temperature is over 40°C (104°F), steels without protective coating may corrode when expose
to water. Applying corrosion prevention material or degassing can be effective measure to prevent corrosion.
Circulating water and supply water should satisfy the standard shown in the table.
Supplied water or make-up water should be supplied by purified water, neutralized water, tap water except
softened water, and industrial water.
14 items in the table is a typical factor for corrosion and/or water scale.
