Spiral pipes, often stacked outdoors and mostly buried underground during use, are prone to corrosion and rusting. To ensure unhindered flow within the pipelines, these pipes must possess strong corrosion resistance.
Once pipes become corroded, they can lead to oil and gas leaks, not only disrupting transportation but also polluting the environment and potentially causing fires and other hazards. Here, spiral pipe manufacturers outline the key factors contributing to the corrosion of spiral pipes:
Failure of Corrosion Protection: It is crucial to ensure proper corrosion protection during pipeline installation or to use anti-corrosive spiral steel pipes directly. Corrosion occurs when the protective coating of the pipe is damaged. The detachment of the protective coating from the pipe surface naturally leads to the failure of corrosion protection. This underscores the importance of selecting anti-corrosive spiral pipes during procurement.
Influence of External Conditions: The primary factors include the nature and temperature of the media surrounding the pipeline, as well as whether these media are corrosive. The degree of media corrosivity is closely related to the microorganisms present in the soil. For long-distance pipelines, the soil environment becomes even more complex. Furthermore, the temperature of the environment where the pipeline is located also affects the corrosion of spiral pipes. Higher temperatures accelerate corrosion, while lower temperatures slow it down.
