China Supplier Low Price Large Stock Steel Pipe Gi A53 Hot Rolled Galvanized Steel Tube Pipe

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 and other manufacturing industries.
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 advantages of galvanized sheet:
1. Galvanized sheet has always been popular for a wide range of environments, and has a long anti-corrosion life.
2. The processing cost is low, and the cost of rust prevention of galvanized sheet is lower than that of other paint coatings.
3. Durable, in suburban environments, the standard galvanized anti-rust layer can be maintained for more than 50 years without repairing. In urban or offshore areas, a standard galvanized anti-rust coating can last for 20 years without repair.
4. Good reliability, the galvanized layer and the steel are metallurgically bonded and become part of the surface, so the durability of the coating is more reliable.
5. The toughness of the coating is strong, and the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use.
6. Overall protection, every part of the plated parts can be galvanized, even in the depressions, sharp corners and hidden places can be fully protected.
7. Save time and effort, the galvanizing process is faster than other coating construction methods, and it can avoid the time required for painting on the construction site after installation.

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.

There is a hot-dip galvanized or electro-galvanized layer on the surface of the zinc 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 line pipes for conveying water, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil pipes in the petroleum industry, especially offshore oilfields, as well as oil heaters and condensate for chemical coking equipment.Coolers, pipes for coal distillation wash oil exchangers, pipe piles for trestle bridges, pipes for support frames of mine tunnels, etc.
