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.
Production process:
Black parts inspection → hanging → degreasing → rinsing → pickling → cleaning → dipping plating aid
→ hot air drying → hot dip galvanizing → internal and external blowing → cooling → passivation and rinsing
→ unloading → inspection and finishing → typing identification → packaging, warehousing and transportation.
Galvanized strip → uncoiling → stretching → rolling pipe → welding → scarring → passivation and rinsing
→ zinc supplement → setting → typing identification → cutting → packaging → drying → weighing.
