Cast Magnesium Anodes
Cast Magnesium Anodes are widely used in the Cathodic
Protection(CP) industry. Cathodic Protection is one of the most common methods of
corrosion mitigation in the pipeline, storage tank and underground metallic
structures.
3N International, Inc.
supplies various shapes and sizes of cast magnesium anodes. The most commonly
used sizes are 9 lb, 17 lb and 32 lb. We also take orders per customers
drawings.
3N packaged
magnesium anodes
are packed in cotton bags with backfill consisting 75% gypsum, 20% bentonite and
5% sodium sulphate, and into plastic bags to prevent moisture. Connecting wire: Standard 10 feet of #12 AWG
solid copper Lead TW wire.
3N packaged magnesium anodes
are ready to install. This provides great
convenience and cost savings for end users who
have the ability and expertise to do the jobs by themselves, as well as for
engineering contractors. 3N International
maintains inventories of packaged magnesium anodes in multiple locations for
prompt delivery to customers.
