High Silicon Cast Tubular Anodes by Anotec

High silicon cast iron anodes have long been used and are very popular in the prevention of corrosion through impressed cathodic protection systems.  These anodes are used to protect various underground or sumberged strutures including pipelines, tanks, and offshore structures.For over 30 years, Farwest has represented Anotec, who crafts the world’s best high silicon cast iron anodes.  Farwest represents Anotec as a distributor and licensed manufacture and custom builds the Anotec line of anodes. The Anotec proprietary chill cast process assures consistent weight and a superior (stronger) microstructure, combating corrosion and outperforming the competition by up to 20%.  Performance Accelerated corrosion tests confirm that Anotec chill cast anodes yield more ampere-years per pound than the competition Anode Composition High Silicon Cast Iron ASTM A518 Grade 3 Chemistry Silicon 14.2 - 14.75% Chromium 3.25 - 5.00% Manganese 1.5% Max. Carbon 0.70 - 1.10% Copper 0.50% Max Molybdenum 0.20% Max Chill Cast in Static Metal Molds Anotec’s proprietary chill casting process assures a solid anode that will outperform the competition. Can withstand drop impact tests to more than twice the height of sand cast anodes. ISO 9001 Quality Control Anodes are manufactured, inspected, and tested in accordance with stringent procedures to ensure high quality. Tubular Anode Features Thicker Walls & Connection Area - Improved impact resistance and shipment reliability. Extra thickness at the connection zone where you need it. Reliable Cable Connection - A proprietary zinc connector is hydraulically pressed into an internal taper at the anode center. The cable connection can withstand 2,200 lb force. Low Connection Resistance - Anotec’s quality controlled assembly process ensures a connection resistance less than 0.001 ohms. Performance - Accelerated corrosion tests confirm that Anotec chill cast anodes yield more ampere-years per pound than the competition. Their compact diameter also enhances deep well utilization.

High silicon, cast iron, tubular anodes are used for a variety of cathodic protection applications including deep well anode systems, shallow anode installations, offshore applications as well as many other types of cathodic protection systems.Tubular anodes are popular for their increased surface area, higher current output, centered cable connection and enhanced sealing properties due to the additional sealing materials used inside the anode. Recommended cables sizes are #8, #6 and #4 AWG copper cable, which range in pull strengh from 400 pounds to 1,300 pounds. Available cable insulation types include High Molecular Weight Polyethylene (HMWPE) or dual insulated Halar/HMWPE or Kynar/HMWPE for use in high chloride environments. After the connection is made, it can be sealed with polyurethane or a combination of polyurethane and Novoid A electrical sealant.    Anodes with custom length cable
