Which bacteria results in the corrosion of iron and steel pipes embedd...
Sulphur bacteria are responsible for the corrosion of iron and steel pipes embedded in soil. Here's why:
• Sulphur bacteria are a type of anaerobic bacteria that thrive in environments with little to no oxygen.
• When these bacteria come into contact with iron or steel pipes embedded in soil, they create a corrosive environment by producing hydrogen sulfide gas.
• This gas reacts with the metal to form iron sulfide, which is a brittle and weak compound that causes the metal to corrode and eventually fail.
• The corrosion caused by sulphur bacteria can lead to leaks, bursts, and other types of damage to pipelines, which can be costly to repair.
• In order to prevent corrosion caused by sulphur bacteria, pipeline operators can use various techniques such as cathodic protection, coatings, and biocides.
In conclusion, sulphur bacteria are a major contributor to the corrosion of iron and steel pipes embedded in soil. Understanding the mechanisms behind this corrosion can help pipeline operators take steps to prevent it and maintain the integrity of their pipeline systems.
