Galvanized pipe has a wide range of applications, not only for work manufacturing, but also for mechanical production, etc. It can be described as diverse and wide-ranging.
1. Galvanized pipes are divided into two types: hot-dip galvanized and electro-galvanized. The hot-dip galvanized layer is thick and has the advantages of uniform coating, strong adhesion, and long service life. The cost of electro-galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
2. The purpose of galvanized pipe: now the gas and structure are made of zinc, forming a dense quaternary crystal, which forms a barrier on the steel plate, thus effectively preventing corrosion factors from penetrating. The corrosion resistance comes from the strong protective function of the barrier layer of zinc. When zinc is used for sacrificial protection on the cut edges, scratches and scratches of the coating, zinc forms an insoluble oxide layer to perform a barrier protection function.
