Canister anodes are the perfect impressed current anode for shallow vertical and horizontal surface groundbeds, as well as wet, marshy soil conditions where caving is likely to occur. 7 Steffel GmbH www.steffel.com Tel: +49-5145-9891-0 Im Bulloh 6 [email protected] Fax:+49-5145-9891-90 29331 Lachendorf Germany Cathodic Corrosion Protection The primary anode element (FeSi Anode) is placed in a galvanized steel Canister filled with Coke backfill. The stable anode element passes current to this highly conductive calcined petroleum coke backfill. The backfill is well compacted inside the galvanized steel canister. To allow moisture to quickly migrate to the coke backfill for increased electrical conductivity, the anode is electrically connected to the steel canister, thereby accelerating the canister corrosion rate once the anode has been installed and energized. Mixed Metal Oxide Anode (MMO) To obtain the highest level of protection from an impressed current Cathodic Protection system, an anode with a very low consumption rate and high current capacity will be perfect. With mixed metal oxide anode, you get powerful protection and unsurpassed stability. The anodes are made using titanium substrates which are coated with a mixed metal oxide catalyst. The catalyst is thermally applied to the titanium to form an extremely chemical resistant bond. This special composition brings together the stability of titanium with the conductive properties of the mixed metal oxide catalyst to achieve superior performance and a very low consumption rate. Maximum allowable 12 V operating voltage Consumption rate 1 mg/A.y Maximum Current density 500 A/m2 (in Sea water) Maximum current density 100 A/m2 (in Coke or Fresh water) Maximum anode life 50 year 8 Steffel GmbH www.steffel.com Tel: +49-5145-9891-0 Im Bulloh 6 [email protected] Fax:+49-5145-9891-90 29331 Lachendorf Germany Cathodic Corrosion Protection Applications Mixed metal oxide anodes have proven to operate effectively in all types of environments including areas with extremely low pH levels less than 1, and high chloride concentrations. MMO Rod anode MMO rod anodes perform well in all types of environments. Their mixed metal oxide coating prevents substrate attack in even highly acidic environments. The anodes have been used with great success in deep and conventional groundbeds, and in fresh, brackish and salt water electrolytes. These anodes can be used either bare or packaged in canisters containing petroleum coke breeze. For aqueous environments, the anodes can also be provided in a specially designed PVC perforated tube that directs current flow and provides extra protection to the anode.

With tubular mixed metal oxide anode, you get powerful protection and unsurpassed stability. The anodes are made using tubular 9 Steffel GmbH www.steffel.com Tel: +49-5145-9891-0 Im Bulloh 6 [email protected] Fax:+49-5145-9891-90 29331 Lachendorf Germany Cathodic Corrosion Protection titanium substrates, which are coated with a mixed metal oxide catalyst. The catalyst is thermally applied to the titanium to form an extremely chemical-resistant bond. In soil and fresh water applications, the anodes have a recommended current density of approximately 100 amp/m2, and can be operated over 500 amp/m2 in sea water environments. Even at these relatively high discharge levels, the anodes will be consumed at less than 1.0 mg/amp- yr. The tubular configuration provides a larger surface area, which in turn permits greater current output and lower anode-to-electrolyte resistance. The tubular style also means lead wire connections can be made in the center of the anode. This connection is protected from moisture intrusion by a waterproofing sealant, which fills the entire anode tube. The ends of the anode are then covered with shrink tubing for a completely sealed electrical connection. Mixed metal oxide anodes have proven to operate effectively in all types of environments including areas with extremely low pH levels less than 1, and high chloride concentrations. They can be used singularly; their unique configuration also makes them ideal for use in strings on offshore platforms, deep well groundbeds or above ground storage tanks. In addition, the string anodes can be installed parallel to transmission pipelines, or used for other special applications. This anode can be used also in Canister. Diameter Length Max.

The current passes from the centre of any tube to the next. The materials used for the different parts of anodes and anode chains are suitable for satisfactory performance with regards to low ph-value and high chloride content of water as well as high concentration of chlorine gas. Anode chains are assembled with the desired length of cable and number of anodes to meet the design requirements.
