Features:
Hot-dip galvanized pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. 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 the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The steel tube substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the steel tube substrate. Therefore, it has strong corrosion resistance.
1. Uniformity of galvanized layer: The steel pipe sample shall not turn red (copper-plated color) after being continuously dipped in copper sulfate solution for 5 times.
2. Surface quality: The surface of the galvanized steel pipe should have a complete galvanized layer, and there should be no unplated black spots and bubbles, and small rough surfaces and local zinc tumors are allowed.
3. Weight of galvanized layer: According to the requirements of the buyer, the weight of galvanized steel pipe can be measured for the weight of zinc layer, and the average value should not be less than 500g/square meter, and any sample should not be less than 480g/square meter.
