Short Description:
Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing 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 pipe.

Hot dip galvanized pipe
It is to make the molten metal react with the iron matrix to produce an alloy layer, so as to combine the matrix and the coating. Hot dip galvanizing is to pickle the steel pipe first. In order to remove iron oxide on the surface of the steel pipe, after pickling, it is cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Most of the processes in the North adopt the process of directly rolling pipe with galvanized strip for zinc supplement.We get pleasure from a very very good standing between our shoppers for our fantastic product quality, aggressive price as well as very best support for Fast delivery DN100 Q195 Q235 Q345 Recycled Welded HDG Gi ERW Pipe Ms Galvanized Seamless Carbon Steel Gi Rectangular Pipes, We look forward to establish a long-term business relationship with your esteem co-operation.
