Hot dip galvanized pipe is an alloy layer made by molten metal and iron matrix reaction. The substrate and coating are combined during the production of hot dip galvanized steel pipe. In order to remove the iron oxide on the surface, hot dip galvanized pipe is cleaned by ammonium chloride or zinc chloride aqueous solution of ammonium chloride and zinc chloride mixed aqueous solution tank after pickling. Then hot dip galvanized pipe is sent into the plating tank. Through a series of complex physical and chemical reactions between hot dip galvanized pipe tube substrate and the molten bath, hot dip galvanized steel pipe is formed with a tight corrosion resistant zinc-ferroalloy layer.
As a professional China steel pipe factory, Tianchuang specializes in manufacturing galvanized pipes and is dedicated to providing the good quality pipes for the customer from the whole world.
First of all, the surface of the galvanized pipe after hot dip galvanizing can be protected. The inside of the tube cavity or any other coating corner is hard to enter so that the entire hot dip galvanized steel pipe is well-protected.
Second, the impact and wear resistance of hot dip galvanized steel pipe become better after the high-temperature process. Because the hardness layer is greater than the hardness of steel.
Third, a major feature of hot dip galvanized steel pipe is occasionally subjected to considerable mechanical damage which makes a small part of the zinc layer off and exposes the iron base.
Finally, the hot dip galvanized steel pipe price is affordable for most customers. There are many professional steel pipe manufacturers in China, thus hot dip galvanized pipe can be produced at a low cost.
