R
Reza Javaherdashti

The document discusses strategies for dealing with microbiological corrosion in gas pipelines. It introduces Dr. Reza Javaherdashti, who has over 20 years of experience in corrosion management and microbiological corrosion. It notes that dry gas pipelines can still experience microbial corrosion. Hydrostatic testing can induce microbial corrosion. The document provides facts about microbiologically influenced corrosion and lists some examples of corrosive bacteria, including sulfate-reducing bacteria and iron-reducing bacteria. It recommends strategies for dealing with microbiological corrosion, such as recognizing damage, evaluating risk, assessing treatment programs, gaining engineering knowledge, and applying Dr. Javaherdashti's corrosion management method.

Microbial Corrosion!
MIC in gas pipelines 1. Even so-called Dry Gas is not completely dry, it has a water phase in which microbial corrosion can find an opportunity to appear. 2. MIC can be induced via hydroststic testing (a test applied to test strength and leakage resistance of welding)
Some Facts Microbiologically influenced corrosion (MIC) is electrochemical corrosion initiated , enhanced or inhibited by, but not limited to, bacteria. Many engineering materials including metals and non-metals (e.g., concrete, and polymers) have been reported to be prone to MIC/MID. This corrosion phenomenon can be called as :Microbiologically induced corrosion (some researchers try to distinguish between induced and influenced but NACE prefers influenced), microbial corrosion, biocorrosion, biofouling, biological corrosion All the above may be used with some reservations in place of each other but what is definitely wrong is to address it as bacterial corrosion: MIC does not contain bacteria only!

What to do!
1. Recognise the extent of damage 2.Evaluate the associated Risk 3. Assess the most feasible treatment programme 4.Establish engineering knowledge via training 5. Apply Javaherdashti method in corrosion management (define the involved corrosion problems, understand the available treatment methods, apply the treatment, feedback and evaluations, put it in writing!)
