Half Shell Aluminum Bracelet Anode (Tapered End, Bolted)

This indium-activated aluminium bracelet anode is specifically designed for the cathodic protection of submarine/offshore pipelines. The half-shell bracelet anode, consisting of two semi-circular sections, is clamped around the pipeline. The electrical continuity between the anode body and the pipe is allowed by a steel continuity bar or by an electrical cable. With tapered ends, our half-shell aluminium bracelet anodes are suitable for easy movements over stringer during pipeline laying.
