Anti-corrosion Spiral Steel Pipe
There are types of corrosive media in the anti-corrosion spiral steel pipe, such as acid, alkali, salt, oxidant and water vapor. The coating must be chemically inert and resistant to acid, alkali and salt corrosion.
Primer of anti-corrosion spiral steel pipe: It is composed of polyurethane polyethylene, modified epoxy resin, non-toxic anti-rust pigments and fillers, additives, etc. It is cured at room temperature to form an interpenetrating network, the coating film structure is dense, also they are anti-acid, alkali, salt, and anti-rust.
Topcoat of anti-corrosion spiral steel pipe: It is composed of epoxy, rubber resin modification, non-toxic anti-rust pigments and fillers, and additives. They has excellent chemical resistance, non-toxic, anti-microbial erosion.
