Sacrificial anodes is a rotecting cathode unit for metal constructions in marine and harbor industries. Its properties are in compliance with the requirement of the GB/4950-2002. Sacrificial anodes are used in applications for protecting the pipelines and marine structures from corrosion in seawater and saline mud. Zinc anode also suitable for the protection of storage tanks, fishing boat, submarine, stern drive and offshore platform, etc.
