In some parts of the pipelines, where the insulation kit is used to insulate two parts of the pipe in the place of the flange, it is possible that due to induction or the occurrence of lightning, a large potential difference may occur between the two parts of the flange, as a result of which the insulation of the flange will be destroyed. be made In these places, zinc anodes are used as ground electrodes to prevent such problems. The chemical composition of these electrodes is similar to zinc anodes (type 2) and they are produced according to the ASTM-B418 standard. Ground connection batteries can be double or quadruple and their set is placed behind a special strap like zinc anodes.
Zinc anodes should not be used in alkaline environments (with a pH higher than 9.2) and in acidic environments (with a pH lower than 5) and at a temperature higher than 60 degrees Celsius.

Usually, a copper cable with a section of 10 mm2 or 16 mm2 is used for connection, and the copper cable is welded to a steel insert inside the electrode. The junction of copper cable and steel rod is covered with epoxy resin.
