Galvanized pipe, also known as galvanized steel pipe, is divided into two types, hot galvanizing and galvanizing. Hot dip galvanized zinc coating is thick, which has the advantages of uniform coating, strong adhesion and long service life. The cost of galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of the hot galvanized pipe.
In order to improve the corrosion resistance of the steel tube, the Ji'nan galvanized pipe manufacturer galvanized the steel tube. The galvanized steel tube is divided into two kinds of hot dip galvanizing and galvanizing, the hot galvanized zinc coating is thick, the electrogalvanizing cost is low, and the surface is not very smooth. Oxygen blowing pipe: used for steel smelting blowing tube, usually with a small diameter welded pipe, in order to prevent corrosion, some effective aluminizing treatment.
The old house is most are now galvanized pipe, gas and heating with the kind of pipe and galvanized pipe, galvanized pipe as a water pipe in Ji'nan, after a few years of use, produce a lot of rust in the tube, the outflow of water not only pollute the sanitary ware, and mixed with smooth inner wall of bacteria breeding, corrosion caused by the heavy metal content in the water too high, serious harm to human health.
