Magnesium Anodes are used to apply Cathodic Protection to a variety of structures. They are manufactured in a comprehensive range of shapes and sizes.
Magnesium Anodes are used to apply Cathodic Protection to a variety of structures. They are manufactured in a comprehensive range of shapes and sizes. The magnesium is available in two grades, BAC High purity ISOROD, and BAC ISOMAG.
The anode casting has a central steel insert to ensure even dissipation of the anode material over time. The cable connection is brazed to the steel insert and epoxy resin encapsulated.
Performance can be improved by retaining moisture thus reducing the resistivity of the electrolyte local to the anode. To help do this, pipeline anodes can be supplied packaged in a cotton bag containing a backfill of Gypsum, Bentonite and Sodium Sulphate.
Alternatively the backfill can be provided loose, in a variety of compositions, for site application.
Standard Backfill Composition:
Powdered Gypsum 75%
Granular Bentonite 20%
Sodium Sulphate 5%
The anode and backfill are contained in a cotton bag
