Product Description

Zinc-aluminum-cadmium alloy sacrificial anode

1 The Executive standard
GB/T 4950-2002
SY/T0019-97

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.

3 The scope of application
Zinc alloy sacrificial anodes are suitable for ships in sea water, brackish water media, ballast tanks, mechanical equipment, marine engineering and seaport facilities, drilling platforms, port terminals, seawater media condensers, water pumps, and pipelines in low-resistivity soils , Cathodic protection of metal corrosion protection for facilities such as cables.

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.
