| Zusammenfassung: | The utility model discloses a sewage pipeline with high efficiency, corrosion resistance and high strength for water supply and drainage engineering, which comprises a pipeline body, the surface of the pipeline body is coated with an anti-corrosion coating, and the inner cavity of the anti-corrosion coating comprises an epoxy asphalt coating, an ethylene peroxide coating and a phenolic aldehyde acid-resistant coating. The inner surface of the epoxy asphalt coating is coated on the outer surface of the ethylene peroxide coating, and the inner surface of the ethylene peroxide coating is coated on the surface of the phenolic aldehyde acid-resistant coating. The anti-corrosion function can be achieved by adding the anti-corrosion coating, the epoxy asphalt coating, the ethylene peroxide coating and the phenolic aldehyde acid-resistant coating, the use efficiency of the blow-off pipeline is improved, the trouble of a user is solved, the anti-wear function can be achieved by adding the wear-resistant coating, the n |
