Causes of rust and corrosion of spiral steel pipes

Since spiral steel pipes are stacked outdoors and most of them are buried underground when in use, they are easy to corrode and rust. To ensure the smooth flow of pipes, spiral steel pipe manufacturers are required to 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 fires and cause 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 microorganisms contained in the soil. And if it is a long-distance pipeline, the soil environment will be more complex. In addition, the temperature of the environment in which the pipeline is located will also affect the corrosion of spiral steel pipes. If the temperature is higher, the corrosion rate will be accelerated, while if the temperature is low, the corrosion rate will be slower.

2. It means anti-corrosion failure. When erecting the pipeline, anti-corrosion work must be done or anti-corrosion spiral steel pipes must be used directly. The reason why the pipeline is corroded is because the anti-corrosion layer of the pipeline has been damaged. Once the anti-corrosion layer and the pipe surface are separated, the anti-corrosion failure will naturally occur. This is also the ladder type. When purchasing spiral steel pipe manufacturers, we must choose anti-corrosion spiral steel pipe manufacturers.
