4. Product Description
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.
