Round ASTM Sacrificial Aluminum Anode for Subsea Pipelines
Aluminum Bracelet anodes for pipeline
Aluminum anodes have long been used in the fight against corrosion. The Pier and Piling anodes are designed for use on offshore structures such as piers, pilings or other structural support steel in need of sacrificial cathodic protection. The cast-in anode core is either welded, bolted, or clamped to the structure that is to be protected to ensure a reliable, low resistance connection.
Specifications:
Sacrificial Aluminium Anodes are simple and economical that it could be performance under a variety of environmental conditions, after proper installation that Aluminium anodes will performance efficiently and continuously without any attention for CP systems.
With its perfect performances, it could be widely used for the cathodic protection systems of seawater, pipelines, offshore structures, ship hulls, tanks, boilers, piers, etc.
