Zinc-aluminum-cadmium alloy sacrificial anode

1 The Executive standard

GB/T 4950-2002

SY/T0019-97

Zinc-aluminum-cadmium alloy sacrificial anode-1

2 The main performance

The anode has low self-melting, high current efficiency, and good self-regulating performance of anode current; the protection period is long, up to 20-30 years, and the phenomenon of "over protection" generally does not occur.

4 The product features

The zinc-aluminum-cadmium series (ZAC series) sacrificial anode is cast by alloying with high-purity zinc, aluminum and cadmium. This product has been approved by China Classification Society (CCS), and its quality standard complies with GB/T 4950-2002 standard. The chemical composition of zinc anode complies with US MIL-A-18001H and ASTM-B418 (Type 1) standards. The anode used in the pipeline complies with SY/T0019-97 (design code for sacrificial anode protection for buried steel pipelines). Different specifications and sizes can be customized according to customer requirements!

5 The Instructions for use

When used in the soil, the soil resistivity should be less than 5Ω.m, and it can be expanded to 30Ω.m when the soil is wet.
