Cathodic Protection Calculation

The first thing you need to determine when calculate cathodic protection for pipeline is its cross-sectional area. In case for pipeline we can do it as:


After we get the cross-sectional area, now we need the area required for protection.

We calculate the required current using this formula:

Consumption rate

Total Anode Weight

Total Amount of Anode
