Product Parameters
Execution Standard:GB/T4950-2021 GB/T21448-2017
Main Performance: Low anode self-dissolution, high current efficiency, good self-regulation performance of anode current; long protection lifespan, up to 20-30 years, generally no 'over-protection' phenomenon occurs.
Applicable Scope:Zinc alloy sacrificial anodes are suitable for cathodic protection of metals in seawater, brackish water media, ships, ballast water tanks, mechanical equipment, marine engineering and port facilities, drilling platforms, port docks, seawater medium condensers, water pumps, and pipelines, cables, etc. in low resistivity soil.
Product Features:Zinc-aluminum-cadmium (ZAC) sacrificial anodes are cast from high-purity zinc and aluminum, cadmium alloy. This product is recognized by the China Classification Society (CCS), and the quality standards meet GB/T4950-2021 standards. The chemical composition of zinc anodes complies with USMIL-A-18001H and ASTM+B418 (Type 1) standards. The anodes for pipelines also comply with GB/T21448-2017 'Design Specification for Cathodic Protection of Buried Steel Pipelines with Sacrificial Anodes'. Different specifications and sizes can be customized according to customer requirements!
