Do galvanized pipes need to do anti-corrosion treatment when installing underground?

1.galvanized pipe anti-corrosion treatment

Galvanized pipe as a surface galvanized layer of steel pipe, its surface coated with a layer of zinc to enhance corrosion resistance. Therefore, the use of galvanized pipes in outdoor or humid environments is a good choice. However, in some special cases, such as when installing pipes underground, galvanized pipes may also need to be further treated with anti-corrosion coating.

2.When the pipeline is buried in the ground, it is often necessary to consider the corrosion prevention of the pipeline to ensure the safety and service life of the pipeline. For galvanized pipe, because its surface has been galvanized treatment, it has been anti-corrosion effect to a certain extent. However, if the pipeline is in a harsh environment or buried at a large depth, further anti-corrosion coating treatment is required.

3. how to carry out anti-corrosion coating treatment

When the anti-corrosive coating of galvanized pipes is treated, it can be applied with paint or coating with good corrosion resistance, it can also be wrapped with anti-corrosive tape, and it can also be epoxy-coal asphalt or petroleum asphalt. It should be noted that when performing anti-corrosion treatment, it is necessary to ensure that the pipe surface is dry and clean to ensure that the coating can be firmly attached to the pipe surface.

4. Summary

Under normal circumstances, galvanized pipe has a certain anti-corrosion effect and can be directly used for buried use. However, in the case of large pipeline burial depth and harsh environment, further anti-corrosion coating treatment is needed to extend the service life of the pipeline. When performing anti-corrosion coating treatment, it is necessary to pay attention to the quality of the coating and the use environment to ensure the durability of the anti-corrosion effect and the stability of the performance.
