Galvanized pipe is a steel pipe with a galvanized surface, which is divided into two processes: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanized pipe is to immerse the steel pipe in molten zinc liquid to form a thicker zinc layer, which has strong anti-corrosion performance and is suitable for outdoor and humid environments; electro-galvanized pipe forms a thinner zinc layer through electrolytic reaction, with a smooth appearance but slightly weaker corrosion resistance, and is mostly used in indoor occasions.
Galvanized pipe has the advantages of corrosion resistance, long life and low cost. It is widely used in construction, municipal administration, agriculture, industry and other fields, such as water supply, gas, structural support, HVAC pipelines, etc. Its specifications are diverse, with diameters ranging from a few millimeters to hundreds of millimeters, and can be customized according to needs.
