ASTM A53 Galvanized Steel Pipe is formed by reacting molten metal with an iron matrix to produce an alloy layer that combines the matrix and the coating. Galvanized Steel Pipe is divided into cold galvanized steel pipe and hot-dip galvanized steel pipe. A53 galvanized steel pipe is pickled first, in order to remove iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the Hot dip bath. A53 steel pipe has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe substrate has a complex physical and chemical reaction with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a dense structure, which has strong corrosion resistance. Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobiles and other industries, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries. Galvanized steel pipe is a Welded Steel Pipe with hot-dip galvanized or electro-galvanized coating on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized pipes are widely used. In addition to being used as pipes for general low-pressure fluids such as water, gas, and oil, it is also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, as well as oil heaters and condensers. in chemical coking plants. Cooler pipes, coal distillation washing oil exchangers, trestle pipes, mine tunnel support frames, etc.

Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
Galvanized steel pipe is a welded steel pipe with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensers in chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, and pipes for trestle piles, supporting frames for mine tunnels, etc.
The process flow is:
black tube - alkali washing - water washing - pickling - water rinsing - dipping aid - drying - hot dip galvanizing - outside blowing - inside blowing - air cooling - water cooling - Passivation - water rinsing - inspection - weighing - storage.
