Activity Control arises from the enhancement of the metallic corrosion rate
due to aerobic and anaerobic bacteria.
bacteria produce Sulphuric Acid that aids Localized Corrosion
bacteria produce Hydrogen Sulphide Acid that aids Pitting Corrosion and that
is the most prominent agent in Hydrogen-Induced-Corrosion (HIC).
detects the presence and growth of bacteria colonies on metal surfaces. It
consists of steel studs mounted in a PTFE head screwed on a AISI 316 body; it
is designed for flush mounting in a pipeline. Quantitative Analysis is
obtained by means of electrical current measurements; Qualitative Analysis
performed on the studs removed from the process after a certain time of
exposure allows the operator to identify
to count different kinds of bacteria colonies present.
