Sulphur Reducing Bacteria in Gas Pipelines 1

[TerryStam]

In recent times, a number of burried gas pipelines have been subject to internal corrosion which resulted in pinholes.&nbsp;&nbsp;After preliminary investigations, it has been concluded that the most probable cause for this is Sulphur Reducing Bacteria (SRB).&nbsp;&nbsp;<br><br>I am looking for guidance on SRB's and the most effective way to combat this problem.<br><br>Internal lining is not considered viable at this stage.<br><br>Terry.

 

Terry or readers

I am a Mechanical student in Brasil that is studing pipelines safety, risk management, and also corrosion i n pipelines.
Here in Brazil is very difficult to find good books in engineer, about internal corrosion is impossible. So Im am asking you if you have anything that refer to internal corrosion, please send to me.
My e-mails is written below, please help me.

Treatment for SRB's (Sulfate reducing bacteria) is typically by the use of biocides. Check with your chemical supply company for assistance / guidance.

SRB's can be measured / tested for by culturing the water in nutrients. Again your chemical supplier can assist with this.

There are many other causes of pitting in pipelines, understanding the chemistry and associated damage mechanisms should be your first steps in identifying how to mitigate the damage.
