PVC chemical storage tanks should be avoided in high-corrosive environments.,Regular inspections of the steel body's anti-corrosion condition and proper anti-corrosion measures are essential. The surface treatment methods for carbon fiber, among others, include oxidation, surface coating, plasma treatment, and supercritical fluid processing. A summary of the changes in mechanical properties of carbon fiber reinforced polymer composites after these treatments has been compiled. According to the characteristics of steel-lined plastic storage tanks, high operating temperatures can be90Below °C, high working pressure is determined by the steel plate thickness. The working temperature and pressure are indicated on the drawings if specified. In unavoidable high-erosive environments, the steel body should be coated with epoxy resin and regular anti-corrosion maintenance should be performed.
