Production Process of Hot-dip Galvanized Steel Pipe:
Hot-dip galvanized steel pipe (GI Pipe) has strong corrosion resistance, strength and rigidity, and is widely used in gas, heating and water pipelines. The production process flow of hot-dip galvanized seamless steel pipe is:
Black pipe—Alkali cleaning—Water washing—Pickling—Water rinsing—Immersion aid—Drying—Hot dip galvanizing—Outside blowing—Inside blowing—Air cooling—Water cooling—Passivation—Water rinsing— Inspection—Weighing—Storage.
