The galvanized steel pipe has a galvanized surface that is smooth, compact and uniform in structure. Has good mechanical properties and corrosion resistance. The consumption of zinc is 60%-75% lower than that of hot-dip galvanized steel. The galvanizing process is more complicated, but it must be used for single-sided coatings, double-sided coatings of different thicknesses on the inner and outer surfaces, and thin-walled tubes.
Advantages of galvanized steel pipe: good temperature and pressure resistance, wide application range; good rigidity, suitable for open clothing; easy access to raw materials, co.
