Pre-packaged high-silicon cast iron anodes primarily consist of (chromium-containing) high-silicon cast iron anodes, coke filler, gas conduits, and steel casings. This product offers advantages such as extended service life, easy installation, low grounding resistance, and high discharge capacity. The successful development of this anode body has significantly shortened project construction cycles while effectively ensuring the construction quality of cathodic protection systems. It serves as an ideal cathodic protection material.

Pre-packaged high-silicon cast iron anodes are suitable for cathodic protection of buried metal structures in large-scale long-distance pipelines, urban pipeline networks, hydropower projects, and areas with high surface soil resistivity. They represent one of the primary technologies for long-distance pipelines, urban pipeline networks, and regional protection.
