4.7.9.2 Mixed system pipeline with CCP and functional ground potentials
This mixed system has an insulated pipeline with CCP potential and an uninsulated bar metal
pipe (L
=
1/4
x
flowmeter sensor size) with functional ground potential upstream and
downstream of the flowmeter sensor.
The Fig. 31 shows the preferred installation for cathodic corrosion protection systems.
