Zinc Anode for Port and Offshore Engineering Facilities

Zinc Anode for Port and Offshore Engineering Facilities

Aluminum-Zinc-Cadmium series (ZAC Series) is a sacrificial anode casted by high purity zinc and aluminum, cadmium alloy.

Zinc alloy sacrificial anode is used for the metal anti-corrosion cathodic protection of the ships, water ballast tanks, mechanical equipment, marine engineering and port facilities, drilling platform, wharf, seawater condenser, pump in sea water medium as well as the pipes and cables in low resistivity soil.

Main Performance

1.Small autolysis;

2.High current efficiency and excellent self-regulating property when current occurs;

3.Long protection period up to 20 to 30 years, generally no ‘over protection’ phenomenon occurring.

Implementing Standard

GB/T4950-2002
