Depending on a coating resistivity, water absorption and oxygen permeation, the risk of corrosion of the underlying metal can be light uniform to significant corrosion, SCC or bacterial corrosion
It reveals characteristics being similar to that of TLC or bacterial corrosion
. The right-hand part shows corresponding data with a step size of 2 mm in both directions of the surface.
Several investigators consider that the presence of Sulphate-Reducing Bacteria is the principal cause of bacterial corrosion in natural-water storage and distribution systems.
Sulphide-Producing, not Sulphate-Reducing Anaerobic Bacteria Presumptively involved in bacterial corrosion. Proceedings of the 3rd International EFC worksop on Microbial Corrosion.
Recently, Biosignal announced that BHP Billiton is also contributing funding and resources to test the effectiveness of Biosignal's anti-biofilm compounds in halting bacterial corrosion
Some investigators claim that the most important soil factor indicative of anaerobic bacterial corrosion
is the oxidation-reduction potential (measured in wet soils) as follows: redox probability of attack below 100mv severe 100 to 200 moderate 200 to 400 slight above to 400 noncorrosive

in petroleum product pipelines" Indian Journal of Chemical Technology, vol.
It is generated during gas production or in wet gas pipelines when hydrogen sulfide, carbon dioxide or oxygen are present in the gas, by bacterial corrosion
of the steel, or from construction when lines are not cleaned adequately.
While oxygen is at low levels, it promotes bacterial corrosion even at 0.1-0.2 ppm in pipeline water.
On-line measurements using LPR, the Galvanic Probe and ER probes allows the development of bacterial corrosion to be observed and upsets to be followed, as well as giving rapid indication of changes in the system, as shown in Figure 2.
Bacterial corrosion initiated within days of the line being used, and rose rapidly over the next two weeks, to more than 100 mpy.
