Galvanized pipe, also known as galvanized steel pipe, is divided into two types: hot dip galvanized and electro galvanized. The hot-dip galvanized coating is thick, the coating is uniform, the adhesion is strong, and the service life is long. The cost of galvanizing is low and the surface is not very smooth. Galvanized pipe is a kind of steel pipe dipped with zinc protective layer to prevent corrosion and rusting.

Galvanized pipes are widely used. In addition to ordinary high-pressure fluid pipelines such as water, gas and oil, they are also used in the kerosene industry, especially oil well pipelines, pipelines, condensers, coal distillation oil exchange pipes, bridge pipe piles and mine pipe support pipes in offshore oil fields. Galvanized steel pipe is a welded steel pipe with hot dip coating or galvanized coating. Galvanizing improves the corrosion resistance of the steel pipe and extends the service life.
