Microbial corrosion is prevalent in a range of industries.
However, industries that either heavily use saltwater, freshwater, or chemicals in their operations -- or operate in environments rich in them -- are most prone to biocorrosion risks.
The following are a selection of commonly impacted industries:
Underground pipelines: Clay-type soils and near-neutral pH levels can create concerns when water saturates the area and mixes with decaying organic matter.
Onshore and offshore oil and gas industries: Special care should be taken by those operating in sulphate-reducing bacteria-rich environments.
Nuclear power generation: Increased risk during construction, hydrotest, and outage periods. Susceptible components and structures include carbon and stainless steel piping and tanks. Other metals, such as copper-nickel, brass, and aluminum bronze, may also exhibit corrosion signs and should be monitored.
Water treatment industry: Heat exchangers and piping are particularly susceptible.
Water treatment industry: Particularly those involving natural river or well waters. Stainless steel tanks, pipelines and flange joints are all potential microbial corrosion targets -- especially near welds.
Metalworking industry: The presence of biofilms and changes in local environments can increase wear due to the breakdown of machining oils and emulsions.
