Generally, there are two ways of galvanizing seamless steel pipe, one is hot-dip galvanizing, the other is electro galvanizing. Hot dip galvanizing mainly includes wet process, dry process, lead-zinc process, oxidation-reduction process, etc. As the name suggests, electro galvanizing is the process of forming uniform, dense and well bonded metal on the surface of parts by means of electrolysis.
The zinc coating of galvanized seamless steel pipe is very smooth and compact. In the same kind of steel pipe with good mechanical properties, one is hot-dip galvanizing, the other is electro galvanizing. Hot dip galvanizing mainly includes wet process, dry process, lead-zinc process, oxidation-reduction process, etc. As the name suggests, electro galvanizing is the process of forming uniform, dense and well bonded metal on the surface of parts by means of electrolysis.
The zinc coating of galvanized seamless steel pipe is very smooth and compact, with good mechanical properties and excellent corrosion resistance. The main difference between different galvanizing methods is that when the steel pipe is cleaned with acid, which method can improve the quality of galvanizing. In the actual production, hot-dip galvanizing is generally used, which is mainly due to the relatively complex technology of galvanizing. For some special needs is to use the method of galvanizing.
