Centrifugal Casting Process
Our tubular HSCI anodes are centrifugal chill cast. The casting mold rotates at over 1000rpm producing a g-force that eliminates any trapped gas from silicon iron and throws any impurities to the inside bore of the anode where they do not hinder anode performance. Hence, the metal matrix is tight and dense, increasing the life of the anode.
Low Connection Resistance
With zinc wedge-lock or bolt connectors at the mid-point of the anode, our center connection structure ensures a low resistivity; less than 0.001 ohms. The balanced spread of current throughout the overall length extends the anode lifespan and results in a reliable current discharge to the surrounding environment. Moreover, the connection component is resin encapsulated using a high-quality Epoxy Resin to ensure the eradication of moisture ingress.
Low Consumption Rate
Coarse stippled surface texture enlarges the surface area to weight ratio, thus reducing the anode current density, giving 30% more amp-years than conventional stick anodes.
Easy Installation
A unique cable connection device can be provided for a rapid installation. On average, more than 200 anodes can be connected by two workers in less than eight hours.
ISO 9001 Quality Control
Anodes are manufactured, inspected, and tested in accordance with our stringent quality control procedures to ensure high product quality every time. According to ASTM sampling practice, our anode samples are taken before and after every heat.

Electrochemical Properties
For anodes of the same chemistry and microstructure, variance in consumption is primarily due to the chemical and physical characteristics of the anode environment. The consumption rate does not appear to be significantly affected by current density (amperes per unit area of anode surface). The use of coke breeze around the anode in soil ground beds will tend to lower the consumption rate.
| Environment | Nominal Current Density | Consumption Rate |
| Soil / Fresh Water | 0.2 ~ 0.5 A/ft² (2 ~ 5 A/m²) | 0.2 ~ 1.2 lbs/A.y (0.1 – 0.5 kg/A.y) |
| Coke Breeze | 0.5 ~ 1 A/ft² (5 ~ 10 A/m²) | 0.1 ~ 0.7 lbs/A.y (0.05 ~ 0.3 kg/A.y) |
| Seawater | 1 ~ 5 A/ft² (10 ~ 50 A/m²) | 0.7 ~ 1 lbs/A.y (0.3 ~ 0.5 kg/A.y) |
