When we discuss seamless steel pipe, Seamless steel pipe is with a wide range of applications in our construction industry. in general, Galvanized seamless tube is the hot dip galvanized and electro-galvanized two categories.
The first to introduce hot-dip galvanizing, including wet, dry the, lead, zinc, oxidation-reduction method, etc., the process is very complex, the need for technical maturity to complete. Steel Pipe acid leaching after cleaning, the specific method used to activate the surface of the tube improve the quality of zinc, is not the same, hot dip galvanized main difference.
I do not know understand if understand the electro-galvanized zinc coating surface and compared to a very smooth and dense, homogeneous; the characteristics of the electro-galvanized with good corrosion resistance and mechanical properties; Production is now mainly used in dry and oxidation-reduction method. Coating on one side, the internal and external surfaces of the thickness of the coating on different double-sided smooth coating, and thin-walled tube galvanized to complete this method. Zinc consumption 60% to 75% lower than the hot-dip galvanizing. Electro-galvanized in the operation of technical and general than there is a certain complexity, which requires high technology and conditions in order to complete.
