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

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

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

Question rephrased above and in my neighborhood there are no manufacturers.

Google knows who they are.

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.
