Marine sacrificial anodes are gradually consumed with the outflow of current, hence they are called marine sacrificial anodes. This type of marine sacrificial anode depletes quickly, so their installation position and method must facilitate replacement. Low-potential marine sacrificial anode metal materials include magnesium, magnesium alloys, pure zinc, zinc alloys, aluminum alloys, etc.

Marine sacrificial anodes are suitable for media: seawater, brackish water

Execution standards:

GB/T4950-2002

ASTM-B-418-73, Type 1

The models of marine sacrificial anodes produced by our factory include the ZAC-C series, among others.

Application scope of marine sacrificial anodes:

Subsea pipelines 

Cooling systems of coastal facilities 

Dock steel piles 

Buried pipelines in saline-alkali land (soil resistivity less than 5 ohms) 

Hull, ballast water tanks
