Probe mounting locations
The corrosion probe must be installed in a location that is most susceptible to corrosion. In most cases,
corrosion tends to occur where water is trapped or stagnant. However, it can also accelerate at the bend of
the pipe or where corrosion has occurred previously, but is accelerated by high flow or turbulence.
Location Picture
Incorrect probe location
The probe should not be mounted in a
pipe drop since the corrosive liquid
may not be in full contact with the
electrodes.
Correct probe location
The probe should be mounted in the
riser of a pipe near an elbow where
the velocity is the highest. In general,
probe should be mounted in pipes or
tanks at locations of highest liquid
velocity and constant immersion.
Correct Pipeline Position
Probe can be located at any point on
the pipeline but should always be
immersed in the corrosive material.
