Internal Pipeline Corrosion Protection Using Resistor Controlled Cathodic Protection

Application ID: 76381


Highly alloyed stainless steel used in chlorinated seawater systems may be prone to corrosion under certain operating conditions. Conventional cathodic protection technique is less suitable for stainless steel due to unacceptable anode consumption rate and propensity to hydrogen embrittlement at highly negative potentials.

In the present model, an alternative corrosion protection technique based on resistor controlled cathodic protection is demonstrated using the Current Distribution, Pipe interface.

This model example illustrates applications of this type that would nominally be built using the following products:
