Product Description

Zinc Alloy Sacrificial Anode for Storage Tank

zinc alloy sacrificial anode/zinc sacrificial anode/sacrificial anode for storage tank

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

This product is approved by CCS and its quality standards is in accordance with the GB/T4950-2002 standard. The zinc anode chemical composition conforms to the standard of US MIL-A-18001H and ASTM-B418 (Type 1). The anode used for pipelines is at the same time in line with SY/T0019-97 ‘Design Code for Sacrificial Anode Cathodic Protection of Buried Steel Pipeline’.

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.

Application
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.
