Zinc Alloy Sacrificial Anode
Zinc Alloy Sacrificial Anode
Aluminum-Zinc-Cadmium series (ZAC Series) is a sacrificial anode casted by high purity zinc and aluminum, cadmium alloy.
This product is appovedby CCS and its quality standards is in accordance with the GB/T4950-2002 standard. The zinc anode chemical compostion 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 fo Sacrificial Anode Cathodic Protection of Buried Steel Pipeline’.
Implementing Standard:
GB/T4950-2002
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 occuring.
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, warfs, seawater condenser, pump in sea water medium as well as the pipes and cables in low resistivity soil.
