Coating selection for stainless steel tank outer wall: If there is no insulation layer, usually the parts that are not in contact with the ground or soil need to be considered. Considering the environmental conditions, such as coastal atmosphere, epoxy zinc-rich primer, epoxy mica intermediate paint and polyurethane topcoat are usually used for anti-corrosion. In addition, sometimes it is necessary to consider the operating temperature of stainless steel storage tanks when selecting. 

Coating at the bottom of the outer wall: the part that contacts the ground or soil, usually with the anti-corrosion protection of the outer wall of buried pipelines Similarly, use two coats of epoxy asphalt coating, each125um,common250um. There are also thick-film modified epoxy coatings used as the anti-corrosion coating on the bottom. The thickness of the coating is between200- 300umbetween. 

Anti-corrosion coating on the top: The anti-corrosion coating on the top of the stainless steel tank is the same as the coating system on the outer wall of the tank. The atmospheric corrosive environment needs to be considered. In addition, due to the need for maintenance and monitoring inspections, it needs to be suitable for people to move around on the top of the equipment, so the top is usually made into a non-slip rough surface by evenly sprinkling polyurethane topcoat between two coats.60 -80purpose stone English sand to prevent personnel from slipping during operation.
