Factory Price Square Pipe Black Galvanized Steel Pipe
Galvanized pipe, also known as galvanized steel pipe, is divided into two types: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has a thick zinc layer and has the advantages of uniform coating, strong adhesion, and long service life.
Galvanized pipe, also known as galvanized steel pipe, is divided into two types: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has a thick zinc layer and has the advantages of uniform coating, strong adhesion, and long service life. The cost of electro-galvanized pipes is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
Application
Hot-dip galvanizing pipe reacts molten metal with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to in a hot dip plating 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 zinc-replenishing process of direct coiling of galvanized strips.
