Safe, non-Intrusive and Cost-effective Stray Current Surveys

The Stray Current Mapper (SCM) is a safe and cost-effective way of mapping the
magnitude and direction of stray current interference on a pipeline. These are usually
caused by third party cathodic protection systems (static interference currents) or DC
electrified rail systems (dynamic interference currents).
Most metal pipes have a protective coating to help prevent against the onset of
corrosion. When these coatings are damaged a destructive chemical reaction occurs
at the point of the defect, this causes current to flow from the pipe to the ground.
This current and any other forced onto the pipeline from a foreign source is known as
stray current, and significantly contributes to the corrosion process. The SCM allows
you to completely map and accurately pinpoint from above ground (without connection
to the pipeline) the area where current discharge is taking place (usually coating defects).

The SCM is also capable of data-logging for up to 48 hours, meaning that information
can be stored over a real-time period, then processed and analysed at a later date to
identify both the location and source of the interference.

SPECIFICATIONS / FEATURES
● SCM sensor bar containing multiple magnetometers
● Data viewer and sensor bar control software (to be installed on
customer provided laptop)
● Fully weatherproof housing
● Can withstand 1m (3ft) drops onto concrete
● 48 hours data logging
● Dedicated analysis software
● Simultaneously identify up to four separate interferences (using 4 Si's)
● SmartProbe 2* for use where there are multiple pipes and high interference areas

*When these products are used in conjunction with the SCM, further features are available.

THE SCM BENEFITS:
● Rapid assessment of stray currents from above ground without
connection to the pipeline
● Determine pipeline sections effected by stray currents.
● Pinpoint the stray current pick-up and discharge points
● Display the amplitude and direction of stray currents.
● Identify the source of stray currents.
● Non-intrusively troubleshoot suspected breakdowns in
cathodic protection.
● Provides data to enable negotiation between various parties involved
in stray current interference problems.
● Data logging and archiving for up to 48 hours

WHO WOULD BENEFIT FROM THE SCM SYSTEM?
● Can be used with multiple pipes and high interference sites
● Gas transmission and distribution companies
● Oil transportation companies
● Service companies and contractors in the pipeline industry
● Water and waste pipeline companies
