Galvanized pipe is a metal pipe whose surface is covered with a layer of zinc, which has good anti-corrosion properties and durability. Hot-dip galvanized pipe is a steel pipe that is heated at high temperature and then immersed in a galvanizing solution to form a thick zinc layer, which has high anti-corrosion performance and durability. Electroplated galvanized pipe uses steel pipe as the cathode and deposits a thin zinc layer on the surface through electrolysis, which has good anti-corrosion performance and decorative properties. Galvanized pipes are widely used in water supply, drainage, heating and other piping systems in the construction field and are widely used in sewage, rainwater, tap water and other pipeline systems in the municipal field.
