ASTM A106 A36 A53 Galvanized Square Pipe Hot dip galvanizing is to make molten metal and iron matrix
reaction and produce alloy layer, so as to combine the matrix and
coating. Hot dip galvanizing is the first steel parts pickling, in
order to remove iron oxide on the surface of steel parts, pickling,
through ammonium chloride or zinc chloride aqueous solution or
ammonium chloride and zinc chloride mixed aqueous solution tank for
cleaning, and then into the hot dip plating tank. Hot dip
galvanizing has the advantages of uniform coating, strong adhesion
and long service life.
The principle of hot dipped galvanizing is to immerse cleaned iron
parts into zinc bath under the wetting effect of plating aid,
resulting in iron and steel reacting with molten zinc to produce an
alloyed skin film. A good hot dip galvanizing operation should
ensure that all processes are under strict control and give full
play to the function of the process. And if the operation of the
previous process is not good, it will cause a chain of adverse
reactions in the subsequent process, and greatly increase the
operation cost or cause bad hot dip galvanized products. If the
pretreatment is not good, the molten zinc can not react with steel
normally and completely, forming the most perfect galvanized skin
film tissue. If the post-treatment is not good, it will destroy the
appearance of galvanized skin film and reduce the value of goods Product Specification | ASTM A106 A36 A53 Galvanized Square Pipe | Product Categories | Hot galvanized steel pipe , electrogalvanized steel pipe | | Size | Standard or customized | | Steel plus zinc | Zn coating thickness | 30-650 g/m2 | | Application | Widely used in automobile, construction, household appliances,
