How to ensure the integrity of the zinc layer for hot-dip galvanized flanges

To ensure the integrity of the zinc layer on hot-dip galvanized flanges, it is necessary to control from multiple aspects: strictly clean the flange surface of oil stains, rust and other impurities before plating to ensure the cleanliness of the substrate; Control the galvanizing temperature and time to ensure that the zinc solution fully infiltrates the flange and forms a uniform zinc layer; Avoid collision and friction between the flange and hard objects after plating, and prevent mechanical damage to the zinc layer; Take protective measures during transportation and storage, such as cushioning with soft materials, moisture-proof and rainproof, to reduce environmental corrosion; Focus on inspecting vulnerable parts such as flange edges and holes, and promptly repair any zinc layer peeling to ensure the integrity of the zinc layer in all aspects.
