    HVG MARINE ANODE 0028: Zinc Anode for Buried Pipeline

    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.

    Implementing Standard: GB/T 4950-2002

    Main Performance: Anode has small autolysis, high current efficiency and excellent self-regulating property when current occurs. Its protection period is long up to 20 to 30 years, generally no ‘over protection’ phenomenon occurring.
