Cathodic Protection system

Cathodic Protection system

Cathodic Protection system

(OP)
Hi all
Cathodic Protection system is not envisaged for steel storage tanks and drums having concrete slab type foundation. it is just?

RE: Cathodic Protection system

Is this systems protecting the inside or outside of the tank/drum? Is the tank/drum going to spend a large portion of its time full or empty?

RE: Cathodic Protection system

In order for cathodic protection systems to work, a electrolyte needs to be in contact with the material to be protected so the impressed current can be applied uniformly. This is a precondition that is unlikely to be possible for a tank bottom sitting on a concrete slab.

Cathodic protection can be used on the inside of storage tanks - if the liquid being stored is conductive. If this is a potable water application, see this from water world Cathodic Protection for Above Ground Storage Tanks

Waterworld does indicate cathodic protection of tank bottoms is possible, but the design must overcome e caveats above.
