Processing of transparent enclosure wall of Yangjiang chemical plant

  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
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, the protective fence of the outdoor fence is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or the mixed aqueous solution of ammonium chloride and zinc chloride, and the anti-theft fence guardrail is then sent to the hot-dip galvanizing tank
Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life
In order to improve the corrosion resistance of steel pipes, general steel pipes are galvanized
Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing
The hot-dip galvanizing layer is thick, the cost of electro galvanizing is low, and the surface is not very smooth
Oxygen blowing welded pipe: it is used as steel blowing pipe
Generally, small-diameter welded steel pipe is used, with eight specifications of 3 / 8-2 inches
It is made of 08, 10, 15, 20 or 195-q235 steel strips
In order to prevent corrosion, some shall be effectively aluminized
