Epoxy Composite Steel Pipe And Galvanized Steel Pipe Difference

First, the principle of epoxy composite steel pipe and galvanized steel pipe

1. epoxy composite steel pipe: it is by spraying a layer of epoxy resin coating on the internal and external surfaces of the steel pipe, and adding glass cloth at the internal coating of the steel pipe to enhance the formation of a new type of steel pipe with anticorrosive, anti-abrasion, impact resistance and other characteristics.

2. galvanized steel pipe: it is the ordinary steel pipe surface through the hot dip galvanizing process, the formation of a layer of metal plating with very good corrosion and oxidation resistance, to further enhance the corrosion resistance of the steel pipe.

Second, the use of epoxy composite steel pipe and galvanized steel pipe

1. epoxy composite steel pipe: because of its excellent anti-corrosion ability and strength, mainly used in the transmission of petroleum, natural gas, chemical industry, city water and other high-pressure, high-temperature, highly corrosive environment of the pipeline system.

2. Galvanized steel pipe: It is widely used in various industries such as construction, shipbuilding, electric power, chemical industry, etc. It is used for conveying low-pressure fluids, gas, air, heated steam and water.

Third, the advantages and disadvantages of epoxy composite steel pipe and galvanized steel pipe

1. Advantages of epoxy composite steel pipe: it has good anti-corrosion, wear-resistant and anti-impact properties, long service life, suitable for use in high-pressure, high-temperature, highly corrosive environments.

2. Advantages of galvanized steel pipe: very good corrosion resistance and cost advantage, generally used for low-pressure transmission and indoor construction piping.

3. Disadvantages of epoxy composite steel pipe: higher price, need professional skills construction and maintenance.

4. Disadvantages of galvanized steel pipe: there are great defects in the high corrosion environment, the service life is relatively short.

Fourth, the price of epoxy composite steel pipe and galvanized steel pipe

1. The price of epoxy composite steel pipe is relatively high, generally more than several times more expensive than galvanized steel pipe of the same diameter.

2. The price of galvanized steel pipe is relatively low, in the same specifications, the price is much cheaper than the epoxy composite steel pipe.

In summary, although epoxy composite steel pipe and galvanized steel pipe are both coated steel pipe, there are obvious differences in application areas and characteristics. When choosing, you need to choose according to the specific circumstances and needs, in the right environment to choose the appropriate steel pipe products, not only can reduce a lot of maintenance costs and time, but also to extend the service life of the pipeline.
