HSCI Tubular Anodes

Jennings Anodes has been a leading supplier of High Silicon Cast Iron anodes for over 40 years. We manufacture our anodes in two foundries with a production capacity of 3,000 tons per year. Jennings Foundry previously manufactured all the Durichlor-51 anodes. Our depth of knowledge and experience enables us to provide a comprehensive range of HSCI anodes in tubular form to the highest of standards, meeting X-Ray Level 1 as per ASTM E186/E446, chemistry to either ASTM A518-99 Gr 1 or 3.

HSCI anode is made from the iron alloy which contains 14% to 18% silicon with excellent performance of acid and alkalis resistance. A porous and semi-conductive film of silicon dioxide (SiO₂) forms on the exterior of the anodes to reduce the rate of consumption. 

ASTM A518 Grade 3 alloy is particularly suited for electrolytes rich with chloride ions, where the level of chromium is elevated to enhance anode performance.

Jennings Anodes HSCI Tubular anodes (TA Series) are manufactured using a Centrifugal Chill Cast method. No other method consistently produces tubular anodes with a superior metallic structure than this proven route. 


Product Features


    1. Casting integrity achieved through one directional solidification. Centrifugal Castings are cast using a spinning mold rotating at over a 1000 RPM, on cooling centrifugal castings only cool from the outside diameter to the inside diameter. This ensures the walls of the casting are denser and purer than other casting methods. The anode therefore is made up from a dense, homogenous metal matrix, with no gas inclusions, no porosity and no shrinkage.
    2. Impact resistance. The centrifugal casting in a chill or steel mold ensures greater density and integrity resulting in a stronger anode with improved impact resistance helping to avoid anode breakage during handling and installation.
    3. A low consumption rate. A stippled effect outer surface leads to a large surface area in comparison to anode weight thus reducing the anode current density, giving 30% more amp-years than conventional stick anodes. 
    4. Longer life expectancy. Excellent performance proven by 3rd Party Accelerated Corrosion Testing. 
    5. Low cable connector resistance. A low resistivity (less than 0.001 Ohms) zinc Wedge-lock center connection ensures a balanced spread of current throughout the length of the anode, extending anode lift and resulting in a reliable current discharge to the surrounding environment. The connection is resin encapsulated using a high-quality Epoxy Resin to ensure eradication of moisture ingress.
    6. Ease of connection. A unique cable connection device can be provided for easy and efficient installation. 200 pcs can be connected by 2 people in less than 8 Hours.
