Descrizione di prodotto
Sacrificial Aluminum Bracelet Anodes for Galvanic Corrosion
Sacrificial bracelet anodes are typically made from either zinc alloy or aluminum alloy, depending on design requirements, environmental variables, and water salinity. These anodes provide cost-effective and reliable cathodic protection for submerged pipelines, which are usually coated with anti-corrosion materials and weighted with concrete for negative buoyancy.
Bracelet anodes are mounted at specific locations determined by the cathodic protection system design and are electrically connected to the pipeline via special bonding copper cables. While the primary defense against corrosion is the pipeline's anti-corrosion coating, bracelet anodes protect areas where coating failures may occur during installation or operation.
Applications
These anodes are used for:
- Hull protection
- Ballast tanks
- Offshore engineering
- Harbor structures
- Sea water cooling systems
- Submerged pipelines
