Galvanized pipe is a commonly used pipe material. It uses a hot-dip galvanizing or electro-galvanizing process to coat a layer of zinc on the surface of ordinary steel pipes, which effectively enhances the rust-proof and corrosion-resistant capabilities of the steel pipes. Galvanized pipe has high strength and stiffness and can withstand a certain amount of pressure and weight. It is widely used in construction, plumbing, fire protection and other fields, such as transporting fluids such as water and gas. Advantages include long service life, easy installation, and relatively low cost. But there are also some disadvantages, such as the zinc layer may be affected to a certain extent in humid environments. Overall, galvanized pipe plays an important role in many fields with its unique properties.
