Excess Liquids Cause Pipeline Corrosion
Corrosion is inevitable within a pipeline, however taking a proactive approach to preventative maintenance can save you thousands, if not millions of dollars in repair, replacement, or environmental clean-up costs. Liquids of any kind can pose risks in both oil and gas pipelines. Low spots in oil or gas pipelines can accumulate liquids (condensate or water) causing a breeding ground for bacteria that can cause pitting of the pipeline wall.
What is MIC?
Because water is heavier than oil, water settles in low evolutions of the pipeline route. If a corrosive component in the production fluids is present, the the low areas of the pipeline have the most potential for Microbiologically Induced Corrosion (MIC).
How Pipeline Pigging Can MIC?
Periodic pigging is an effective and efficient way to prevent standing liquids from compromising the integrity of a pipeline. A pigging program that includes the use of pigs with heavy duty bristles and pit cleaning brushes are highly effective in both swiping the liquids downstream, and out of pits. Removing the liquids from the pits allows the pipeline wall to more adequately accept biocides to treat bacteria corrosion.
