Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, exploration machinery and other manufacturing industries.
Galvanized steel pipes are divided into hot-dip galvanized steel pipes and cold galvanized steel pipes. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Cold galvanized steel pipe is electric galvanized, galvanized amount is little, cold galvanized steel pipe galvanized layer is electroplating, zinc layer and steel pipe matrix independent stratification. Zinc layer is thin, zinc layer is simply attached to the steel tube matrix, easy to fall off. So its corrosion resistance is poor.
