Zusammenfassung: | The corrosion-resistant copper-plated steel pipe comprises a steel pipe body and a copper-tin alloy layer, the copper-tin alloy layer is electroplated on the outer surface of the steel pipe body, a first corrosion-resistant mechanism is arranged on the inner wall of the steel pipe body, and a second corrosion-resistant mechanism is arranged on the outer surface of the copper-tin alloy layer. The first anti-corrosion mechanism comprises a first polyurethane anti-corrosion coating layer and a first urushiol anti-corrosion coating layer, the first polyurethane anti-corrosion coating layer is arranged on the inner wall of the steel pipe body, and the first urushiol anti-corrosion coating layer is arranged on the side, away from the steel pipe body, of the first polyurethane anti-corrosion coating layer. The steel pipe body, the copper-tin alloy layer, the first corrosion-resistant mechanism, the first urushiol anti-corrosion coating layer, the second corrosion-resistant mechanism, the second polyurethane anti-cor |
