Since spiral welded pipes are piled outdoors and most of them are buried underground when in use, they are very easy to corrode and rust. In order to ensure the smooth flow of the pipeline, the spiral welded pipe must have strong corrosion resistance.
The influence of external conditions will cause spiral welded pipe corrosion. It mainly depends on the medium characteristics and temperature around the pipeline, and whether the medium around the pipeline is corrosive. Because the degree of medium corrosiveness is closely related to the various microorganisms contained in the soil. And if it is a long-distance pipeline, 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 welded pipe. If the temperature is high, the corrosion rate will also accelerate, while the corrosion rate will slow down at a low temperature.
