ASTM A53 A106 Sch40 Carbon Steel Square Pipe API Black Cold Rolled Galvanized

Products Description

The molten metal reacts with the iron matrix and produces an alloy layer, so as to combine the matrix and the coating. Hot dip galvanizing is the first steel pipe pickling, in order to remove iron oxide on the surface of the steel pipe, 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.

1. Black parts inspection → hanging material → degreasing → rinsing → pickling → cleaning → dipping agent → hot air drying → hot dip galvanizing → inside and outside blowing → cooling → passivation and rinsing → unloading → inspection, dressing → typing labeling → packing into storage and transportation.

Galvanized strip → uncoiling → stretching → rolling → welding → scraping → passivation and rinse → zinc filling → shaping → typing mark → cutting → packing → drying → weighing.

1. Low processing cost: the cost of hot-dip galvanized rust prevention is lower than that of other paint coatings.
