Galvanized Pipe

Galvanized steel pipes are welded steel pipes with hot-dip galvanized or electro-galvanized layers on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and prolong the service life. Future Metal produces galvanized round pipes and galvanized square pipes of different specifications, supports customization of various sizes and standards, such as: 2 inch galvanized pipe,1 inch galvanized pipe,3 inch galvanized pipe,4 inch galvanized pipe,50mm galvanised pipe etc. and has been exported to more than 50 countries and regions such as Chile, Mexico, United Arab Emirates, South Africa, Kenya, Singapore, Brazil, France, etc. , the factory has galvanized tube for sale in stock, if you buy galvanized pipes, please contact us !

Galvanized steel pipe types

Galvanized steel pipes are classified into two types: hot-dip galvanizing and electro-galvanizing

1. Hot dip galvanized pipe

The 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.

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

2. Electro-galvanized steel pipe
The amount of galvanizing of electro-galvanized steel pipe is very small, only 10-50g/m2, the surface is not very smooth, and its corrosion resistance is much different than that of hot-dip galvanized pipe. Regular galvanized pipe manufacturers, in order to ensure the quality, most do not use electro-galvanized (cold plating). Only those small enterprises with outdated equipment use electrogalvanizing, and of course their prices are relatively cheap. Electric galvanized steel pipes (also cold galvanized steel pipes) are no longer used for water and gas pipes.

Features of galvanized pipe

1. Good corrosion resistance

The zinc coating is thick, with detailed, uniform and non-porous crystals, and excellent corrosion resistance.

2. Good ductility

Because the zinc coating has excellent ductility, it can be formed by cold punching, rolling, bending, etc. without damaging the coating.

3. Beautiful appearance and strong decoration

The zinc coating is passivated by chromic acid to form white, colorful, military green, etc., beautiful and generous, with certain decorative properties；The surface of the parts after hot-dip galvanizing is bright and beautiful.

4. Strong corrosion resistance

With iron-zinc alloy layer, combined with compactness, it exhibits unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere

5. Strong wear resistance

Because of the strong combination, zinc and iron are mutually soluble and have strong wear resistance

6. Good flexibility

The pure zinc layer is a layer of galvanized layer endowed with plasticity in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility, so it is rich in flexibility.

Applications of galvanized tube

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 distillate washing oil exchangers, and trestle piles, support pipes for mine tunnels, bridge construction, railway vehicles, highways, sports facilities, industrial machinery, etc.
