Causes of rust and corrosion of spiral steel pipes

Because spiral steel pipes are stacked outdoors, and most of them are buried in the ground when they are in use, they are easy to corrode and rust. To ensure the smooth flow of the pipes, spiral steel pipe manufacturers must have strong corrosion resistance. Once the pipeline is corroded, it will cause oil and gas leakage, which will not only interrupt transportation, but also pollute the environment, and may even cause fire and harm. Factors causing 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 pipeline, and whether the medium around the pipeline 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 in which the pipeline is located will also affect the corrosion of the spiral steel pipe. If the temperature is higher, the corrosion rate will be accelerated, and if the temperature is low, the corrosion rate will be slowed down.

2. It is an anti-corrosion failure. When the pipeline is erected, it is necessary to do a good job of anti-corrosion work or directly use anti-corrosion spiral steel pipes. The reason for the corrosion of the pipeline is that the anti-corrosion layer of the pipeline has been damaged. Once the anti-corrosion layer and the surface of the pipeline are separated, it will naturally cause anti-corrosion failure. This is also the ladder type. We should choose anti-corrosion spiral steel pipe manufacturers when purchasing spiral steel pipe manufacturers.
