Hot Dipped Galvanized Steel Pipe And Tube For Structural Fluid Usage

Product Description

Hot-dip galvanized steel pipe is widely used in manufacturing industries such as construction, machinery, coal mines, chemicals, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery. Welded steel pipe with hot dip galvanized or galvanized surface on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of the steel pipe and prolong its service life. Galvanized pipes have a wide range of uses.In addition to being used as pipeline pipes for water, gas, oil and other general low-pressure fluids, they are also used as oil well pipes, oil pipelines in the oil industry, especially offshore oil fields, oil heaters for chemical coking equipment, and condensation Pipes for coolers, coal-distillation washing oil exchangers, and trestle pipe piles, pipes for supporting frames of mine tunnels, etc. Hot-dip galvanized pipe is made by reacting molten metal with iron substrate to produce alloy layer, so that both the substrate and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. Ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank are cleaned, and then sent to a hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe substrate and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant, tightly structured zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe base. Therefore, its corrosion resistance is strong.

Advantage

The hot-dip galvanized layer is thick, and has the advantages of uniform coating, strong adhesion and long service life. Low cost of galvanized,
