How Microbial Induced Corrosion Occurs and How to Prevent it


When building anything below ground and even above it, any builder, engineer, or contractor and even DIYers want to build to last. As with any major undertaking, there are natural enemies that have to be taken into consideration for a successful build. Microbial induced corrosion can occur on several metals used in several building projects. It is important to understand what causes microbial corrosion and what you can do to prevent it.

Microbial corrosion is when the metabolic activity of microorganisms occurs on metal and cause corrosion. It has been researched and found that there are somewhere around a dozen different microorganisms on earth that can cause corrosive damage to building projects countrywide. In order for microorganisms to live and thrive there have to be certain conditions present. The idea is by eliminating the conditions for their life, you will see no corrosion.

The typical metals that are subject to microorganism corrosion are aluminum, copper, stainless steel, and carbon. Pipes and tanks are two examples of project items that can suffer from microbial corrosion. Projects both onshore and offshore suffer from potential corrosion. The corrosion occurs in both anaerobic and aerobic conditions meaning with or without the help of oxygen.

It is really important to keep areas of possible corrosion, clean. There are also chemicals such as biocide, which can be used, that will not harm the meat yet kill the organic microorganisms that can potentially cause corrosion. It is also suggested to drain and maintain dryness in the concerned areas. Maintenance and keeping a close eye on equipment on a regular schedule is the best way to prevent corrosion.

The best way to prevent the microbial induced corrosion is to make sure that the organisms do not start growing. If you feel that the prevention has been neglected there is still hope. Begin immediately using a killer like a biocide that will prevent any further damage. Your job is not done though; once you have eliminated the microorganisms then you have to come up with a maintenance plan. Make sure that all the necessary prevention actions are taken to eliminate further damage. Once microorganisms are allowed to multiply, they do so very fast.

Microbial induced corrosion can happen anywhere there is oxygen or where there is no oxygen. This can be confusing but every contractor or builder has access to the knowledge to prevent their project material corroding over time. It is important to include longtime maintenance to metals to prevent any sort of microbial corrosive damage. The cost of the maintenance is far less than the damage caused by corroding microorganisms. With not too much effort and a little planning and understanding, anyone can protect their building projects from long-term microorganism damage.
