Product Details

Sacrificial bracelet anodes Cathodic Protection For Pipelines

Sacrificial bracelet anodes

Sacrificial bracelet anodes typically are either a zinc alloy or an aluminum alloy, depending on the design requirements, environmental variables, and water salinity. Both alloy types were used in the fabrication of the anodes for Stream. Sacrificial bracelet anodes, as a true and tested component, are cost effective and reliable for the cathodic protection of submerged pipelines. These pipelines usually have an anti-corrosion coating and along with a heavy concrete mix for negative buoyancy.

Bracelet anodes are mounted in specific locations determined by the cathodic protection system design, and are connected electrically to the pipeline via special bonding copper cables.

The main defense that the pipeline has against corrosion is the anti-corrosion coating. The bracelet anodes are designed to protect the pipeline where any voids, pits, or other coating failures may occur during installation or during the operating life of the pipeline.
