NOTE
ŷ
Circle (O) marks in the chart show the factor relevant to corrosion or water scale.
ŷ
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.
ŷ
Circulating water and supply water should satisfy the standard shown in the table.
ŷ
Supplied water or make-up water should be supplied by purified water, neutralized water, tap water except
softened water, and industrial water.
ŷ
14 items in the table is a typical factor for corrosion and/or water scale.
