Causes of rust and corrosion of spiral steel pipes

Causes of rust and corrosion of spiral steel pipes

Because spiral steel pipes are stacked outdoors, and most of them are buried under the ground when they are used, they are prone to corrosion and rust. To ensure the smooth flow of the pipeline, the spiral steel pipe manufacturer must be relatively resistant to corrosion. . Once the pipeline is corroded, it will cause oil and gas leakage, which will not only interrupt the transportation, but also pollute the environment, and may even cause fire and cause harm. Factors that cause rust and corrosion of spiral steel pipes:

1. The first is the influence of external conditions. The main thing is to first look at the characteristics and temperature of the medium around the pipe, and whether the medium around the pipe is corrosive. Because the corrosiveness of the medium is closely related to the various microorganisms contained in the soil. And if it is a long-distance pipeline, the nature of the soil environment is more complicated. In addition, the temperature of the environment where the pipeline is located will also affect the corrosion of the spiral steel pipe. If the temperature is higher, the corrosion rate will also increase, while the temperature is low, the corrosion rate will slow down.

2. It is anti-corrosion failure. When the pipeline is erected, it is necessary to do a good job of anti-corrosion work or directly use an anti-corrosion spiral steel pipe. The reason for the pipeline corrosion is that the anti-corrosion layer of the pipeline is damaged. Once the anti-corrosion layer is separated from the pipe surface, it will naturally cause corrosion failure. This also reminds us to choose anti-corrosion spiral steel pipe manufacturers when purchasing spiral steel pipe manufacturers.

After reading these reasons cause the spiral steel pipe corrosion. Wish these will help the spiral steel pipe to keep far away corrosion.
