Specialist Coatings and Applications
Coatings for tank internals are often called linings and they may be applied directly to the steel as coatings, or as sheets cut to shape and cemented to the steel to provide a barrier to the liquids in the tank. The choice of coating is generally determined by the nature of the liquid and its corrosivity to the steel. However, with some solutions, tainting with even a small amount of iron corrosion products is not acceptable. Consequently, even a limited amount of corrosion which might not seriously affect the integrity of the tank has to be avoided by the choice of suitable lining materials and application methods.
