High Silicon Cast Iron Tubular Anode

High silicon cast iron anodes (HSCI anode) are among the most widely used for impressed current cathodic protection (ICCP) systems. Their high silicon content forms a continuous thin hydrated silica film, preventing metal pitting. BaiQi’s tubular high silicon cast iron anodes offer exceptional corrosion resistance and low consumption rate in low-pH environments.

Description

BaiQi implements stringent control measures for the chill casting process, adhering to top-tier industry standards: compliant with X-Ray Level 1 per ASTM E186/E446, and chemical compositions conforming to ASTM A518-99 Grade 1 or 3. Specifically engineered for harsh environments (e.g., brackish water, saltwater), ASTM A518 Grade 3 features elevated chromium content to enhance anode performance.
