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.
