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 corrosion resistance of the steel pipes. Galvanized pipe has high strength and hardness and can withstand a certain amount of pressure and weight. It is widely used in construction, plumbing, fire protection and other fields, such as for transporting fluids such as water and gas. Advantages include long service life, easy installation, and relatively low cost. But there are some disadvantages, such as the zinc layer may be damaged under certain conditions. When selecting galvanized pipes, comprehensive considerations need to be made based on the specific use environment and requirements to ensure that it can perform at its best.
