Ji'nan galvanized pipe can be said to be a common pipe in our life, according to the production process can be divided into hot dip galvanized pipe and cold galvanized pipe, is through the method of electro galvanized cold galvanized pipe, a layer of zinc plated steel pipe in the wall, because this method of zinc plating on the surface of steel as a volume layer of zinc, but did not change the chemical composition of the surface of the steel tubes, so that the stability of the zinc plating method is not very high.
Cold galvanizing can also be called zinc plating. Zinc coating is applied to the zinc coating. Then any zinc coating is applied to the surface with any coating method. After drying, zinc filler coating will be formed. It is often used in fire water and common frame structure.
Though the stability of Ji'nan galvanized pipe is not high, its wear resistance is relatively good, that is, because there are some special elements in galvanized pipe, it is the existence of these elements that makes galvanized pipe have good wear resistance. The first is: Although silicon can improve the hardness of steel, but the plasticity and toughness, will decrease; the second is: improve not only can make the tungsten steel hard red performance and heat performance, and improve the wear resistance and galvanized pipe; third is: chromium can make the hardenability of galvanized pipe improvement of wear resistance.
