High Silicon Cast Iron (HSCI) Anodes for Cathodic Protection
At KIG, we specialize in the full spectrum of cathodic protection solutions, offering both Sacrificial Anode Cathodic Protection (SACP) and Impressed Current Cathodic Protection (ICCP) systems. Among our key products, High Silicon Cast Iron (HSCI) Anodes play a vital role in extending the service life of pipelines, storage tanks, and other buried or submerged metallic structures.

Product Overview
HSCI anodes are manufactured from a high-purity iron-silicon alloy, typically containing 14–15% silicon with small additions of chromium to enhance performance. This alloy offers excellent resistance to corrosion in a wide range of soil and water environments, making HSCI anodes a cost-effective and durable choice for impressed current cathodic protection systems.
Our anodes are designed and produced in strict accordance with international standards and NACE specifications, ensuring consistent quality, long service life, and reliable performance in even the most demanding applications.

Specifications
- Material Composition: Material Composition: High-purity iron alloy with 14–15% Si
- Typical Shapes: Solid rods, tubular, and special or custom designs
- Current Output: Stable current efficiency with uniform consumption
- Service Life: 20+ years in normal soil and water conditions
- Coating/Backfill Options: Available with coke breeze backfill or prepackaged for ease of installation
Applications & Uses
HSCI anodes are widely used in ICCP systems for the protection of:
- Transmission and distribution pipelines
- Underground storage tanks
- Offshore platforms and subsea pipelines
- Industrial water intake structures
- Reinforced concrete foundations and bridge piers
By using HSCI anodes within an ICCP system, we deliver consistent current distribution that effectively controls corrosion and safeguards valuable infrastructure assets against long-term degradation.
