Since SSAW steel pipe are stocked outdoors, most of them are buried in the ground during use, so they are easy to corrode and rust. But once the pipeline is corroded, it will cause oil and gas leakage, which will not only interrupt the transportation, but also pollute the environment or may cause fire. So in order to ensure the smooth flow of the pipeline, the spiral pipes must have strong corrosion resistance.

Reasons for the rust of the SSAW steel pipe.

1. Anti-corrosion failure. It is necessary to do a good job of anti-corrosion work or use anti-corrosion SSAW steel pipe directly. The reason why the pipeline is corroded is because the anti-corrosion layer of the pipeline is damaged. 

  2. The influence of external conditions. The main thing is to check the characteristics and temperature of the medium around the pipe, and whether the medium around the pipe is corrosive. 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 SSAW steel pipe. If the temperature is high, it will speed the corrosion rate or conversely, low temperature will lower the corrosion rate.
