[0002] Galvanized steel pipes are welded steel pipes with a hot-dip galvanized or electro-galvanized layer on their surface. Galvanizing can increase the corrosion resistance of the steel pipe and extend its service life. Galvanized steel pipes are already widely used and have the advantages of corrosion resistance and extended service life. For existing galvanized steel pipes, after hot-dip galvanizing, a drying device is required for drying treatment.
