Description

Product Description:

17Ibs prepackaged magnesium anodes are made from an 'active' voltage metal alloy, which is more 'active' than the metal of the structures they are protecting.

At Howah Anodes, supplying customers with the highest standard of sacrificial anodes across the industry is key to our rigorous approach.

17Ibs pre-packaged magnesium anodes are a form of sacrificial anodes and are usually installed to protect buried steel structures, like pipelines and underground tanks. Normally, 17Ibs bare magnesium anodes are centrally packed and in a permeable cotton bag with a backfill mixture and then firmly wrapped in a bag or paper outer lining (usually for shipping purposes) which should be removed prior to installation.

 

Application of 17Ibs/7.7kg 17D3 Prepackaged Magnesium Anode

17Ibs magnesium anodes fight corrosion effectively and economically and are commonly used in marine environments. They protect a variety of steel structures in salt, brackish and freshwater, including:

1. Hulls of ships and various other boats

2. Water storage tanks

3. Piers, docks, and wharfs

4. Pipelines
