METHOD OF PRODUCTION INNOVATIVE HEAT EXCHANGERS WORKING IN EXTREME CONDITIONS

Method of production innovative heat exchangers working in extreme conditions working in extreme conditions with a usage of coating deposition, characteristic in that, an anticorrosive protective coating is sprayed or deposited manually on the outer surface of tubes of heat exchangers. The protective coating consists of two layers: - the first layer (the primer layer) is the heat-resisting ground Termo-Grunt which is based on silicone resin of thixotropic consistency with stabilizing additives, and pigmented with aluminium and zinc dust. The content of solid matter does not exceed 60% of volume. The thickness of the primer layer should not exceed 100 µm (dry) or 190 µm (wet); - the second layer (the surface layer) is made of the paint Termo- Emalia based on silicone resin of thixotropic consistency with stabilizing additives, and pigmented with aluminium dust. The content of solid matters does not exceed 40% of volume. The thickness of the surface layer should not exceed 100 µm (dry) or 275 µm (wet). The time of painting of the layers amounts from 10 to 48 hours depending on the humidity of the environment. After painting the coating is hardened thermally at 200 ° C for at least 2 hours. The thickness of the dry depositing anticorrosive protective coating amounts from 10 µm up to 400 µm, preferably 200 µm. Method of production innovative heat exchangers working in extreme conditions working in extreme conditions with a usage of coating deposition, characteristic in that, an anticorrosive protective coating - the Blygold PoluAl-XT coating based on polyurethane with the addition of aluminium (the thickness of the depositing anticorrosive protective coating amounts from 1 µm up to 400 µm, preferably 200 µm), is deposited manually or automatically on the outer surface of tubes of heat exchangers.
