The anti-corrosion team of Anqing Petrochemical Inspection and Security Company has recently applied the arc spray aluminum anti-corrosion technology to the inner wall of No. 304 oil tank of the Storage and Transportation Department for the first time. The application of this new technology has changed the anti-corrosion construction technology of oil tanks and towers in the past. The new technology of arc spraying aluminum on the inner wall of the tank can completely solve the problem of corrosion of the inner wall of the tank and has a broad market prospect. In the past, anti-corrosion of the inner wall of the oil tank was conducted with anti-static coating. Since the tank often contains various corrosive media, corrosion resistance of the paint is often affected. The average service life is only 5 years. The use of arc spray aluminum anti-corrosion construction, the service life of more than 15 years, at the same time for the company to reduce the cost of maintenance costs. According to calculations, a 5,000 cubic meter oil tank adopts a new technology to save annual direct maintenance costs of 20,000 yuan, while reducing the number of maintenance and considerable indirect costs.
