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:
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
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
While oxygen is at low levels, it promotes bacterial corrosion even at 0.
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.
