What is the life of hot-dip galvanized steel pipe

Hot-dip galvanized steel pipe is also called galvanized steel pipe. The reason why it is called galvanized steel pipe is that it is specially treated, such as galvanizing process. Zinc plating means galvanizing on the outer or inner wall of steel pipe to improve anti-corrosion effect. Its service life, most of the cold-galvanized steel pipes in China are currently used in industry, and only hot-dip galvanized steel pipes are still used in cities. Then the service life of galvanized steel pipe is what we are most concerned about. The following small series introduces how long the steel pipe after galvanizing process can be used.Galvanized Steel Coil Manufacturer

Hot-dip galvanized steel pipes have a long service life, and galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. The galvanized steel pipe used in the city can reach 30 years. The galvanized steel pipe used in other corrosive areas has a longer life and can be used for a long time mainly depending on the thickness of the galvanized layer of the steel pipe.

After the steel pipe is galvanized, it has basically played a role of anti-rust, and it is no longer necessary to do other anti-rust treatment. If you want to further improve the anti-rust effect, you can use the physical anti-rust method, that is, apply a layer of anti-rust paint or spray a layer of anti-rust paint.

Galvanized pipes are widely used, in addition to pipelines for general low-pressure fluids such as water, gas, oil, etc., and also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensation of chemical coking equipment. Cooler, coal distillate oil exchanger pipe, and trestle pipe pile, support pipe for mine tunnel, etc.

The anti-corrosion period of galvanizing is long, but the years of anti-corrosion are different in different environments: 13 years in heavy industry, 50 years in the ocean, 104 years in the suburbs, and 30 years in the city. Zinc plating has essentially played a role in rust prevention, eliminating the need for additional rust protection. If you want to further improve the anti-rust effect of galvanized steel pipe, you can use the physical anti-rust method, that is, the surface is treated with anti-rust paint.steel coil manufacturers

About the long service life of hot-dip galvanized steel pipe? The content is here. At present, the use of cold-galvanized steel pipe has been completely banned in China. The service life of cold-galvanized steel pipe is obviously lower than that of hot-dip galvanized steel pipe. Be sure to know if you need hot-dip galvanized steel or cold-galvanized steel.
