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,
