Hello can anyone advise if cathodic protection for buried industrial pipe systems has always a current injection device?

RE: Pipe corrosion protection

This forum is not for advertising or publicity, only technical questions. There are many, many suppliers of pipeline anticorrosion products. You can Google them.

RE: Pipe corrosion protection

Great. Thanks.
The best one is one in your neighborhood and we don't know them anyway.

RE: Pipe corrosion protection

Google knows who they are.

RE: Pipe corrosion protection

There are two types of cathodic protection systems:

Sacrificial Anode: DC current is obtained from more active metal anodes that are connected directly to the structure.

Rectified Anode: DC current is obtained from more noble (inert) metal anodes that are powered by a rectifier/transformer.
