6205 COSASCO® Two-Inch System Bio-Probe

The bio-probe is used to collect samples of bacteria in Oil and gas systems, including refineries, offshore platforms, pipelines, etc.. Bacteria may be present in a system as either sessile (attached to the metal surface), or planktonic (present in the process fluid). There can be considerable differences between the types of bacteria present in either of these two forms. From a corrosion perspective, the sessile bacteria are the ones that are of primary importance since these are the ones that affect the corrosion, and the ones that must be controlled with chemical treatment. For this reason fluid samples for testing of bacteria only test for planktonic bacteria and may be of no relevance at all to corrosion.

Features:

Meets NACE MR0175 and MR0103
Five Sample Elements for Analysis
Material — 316 S.S.

The bio-probe has five sample elements, each with an exposed frontal area of 1cm². Each time a sample is required for analysis a successive element is removed and replaced with a new one, leaving the other four in place. With this successive change of elements, a longer exposure is obtained for each element, but still permits a relatively frequent sample to be taken for analysis. For example, a sample may be removed every two weeks, but each element will have a 10 week exposure to the process fluid. Formulas for sizing the Bio-Probes are shown to the right.

MIC is most commonly found in systems that contain metal alloys that are most susceptible to corrosion, including mild steels, stainless steels, aluminum alloys, copper alloys, and nickel alloys. Bio-probes offer plant operators a simple and effective tool for collecting samples for subsequent microbiological analyses in systems vulnerable to MIC. These systems include:

Petrochemical & chemical process plants: Stainless steel tanks, pipelines and flanged joints in stainless steel and carbon piping and tanks; copper-nickel, stainless, brass and aluminum bronze
Nuclear Power Plants: cooling water pipes and tubes
Oil & Gas Production: oil and gas handling systems, particularly in those environments soured by sulfate reducing
bacteria (SRB)-produced sulfides; waterflood systems
Water Treatment: heat exchangers and piping
Aviation: fuel storage tanks

Early detection is the key to controlling MIC once it has infected the system. Once the microorganisms have formed a bio-film, they become more resistant to biocides and can rapidly grow if not detected and controlled. Cosasco retrievable and retractable bio-probes offer:

Simple and economical means of collecting bacteria samples
Indicator for effective use of biocide treatments, reducing costs and minimizing dangerous effects to environment
Flush Probe design ideal for frequently pigged pipelines
Use in high or low pressure system, without the need for system shutdown
