Galvanized Steel Pipe

Galvanized Steel Pipe is a kind of Carbon Steel Pipe, mostly Welded Pipe, Galvanized steel pipes are divided into cold galvanized steel pipes (electro galvanized steel pipes) and hot-dip galvanized steel pipes. At present, hot-dip galvanized steel pipes are mainly used in fire protection, electric power and highways.

Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for water transmission, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil transmission pipes in the petroleum industry, especially in offshore oil fields, as well as pipes for oil heaters, condensing coolers, coal distillation oil washing exchanges of chemical coking equipment, as well as trestle pipe piles, support frames of mine tunnels, etc.

Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc.

Hot-dip galvanizing (HDG) is the process of coating iron, steel or ferrous materials with a layer of zinc. This done by passing the metal through molten zinc at a temperature of 860°F (460°C) to form zinc carbonate (ZNC03). Zinc carbonate is a strong material that protects steel and can prevent corrosion in many circumstances. Hot-dip galvanizing can be carried out cheaply and in large batches.
