Ref: CTS-MDS-02-03-Rev2 Impressed Current Anode MMO TUBULAR ANODES Application CTS supply MMO coated tubular anodes for use in shallow and deep groundbeds with or without canisters. The anodes are light weight and extremely durable both mechanically and also under the severe conditions found in deep groundbeds. The anode consists of a proprietary mix of Iridium and Tantlaum oxides on a Titanium substrate conforming to ASTM specifications. The tubular construction allows a low resistance centre connection to be made. Cable type can be varied to suit the environment in which the anode will operate. MMO Tubular anodes are generally used in carbonaceous backfill which extends anode life and increases the permissible operating current. The following table gives recommended maximum current densities in different environments. It is possible to achieve a longer life by increasing coating density or reducing anode current density. Anodes are available in 19, 25 and 32mm diameter as standard with lengths up to 1.2m. Quality Assurance Strict quality procedures are followed throughout the coating process to ensure proper adhesion and loading. Each batch is subjected to thorough testing including: • Review of Mill certs for Titanium substrate (ASTM B338 Grade 1 or 2) • Accelerated life testing in 150g/l H 2 SO 4 at 15000A/m2 Environment Calcined Petroleum Coke & Freshwater Seawater Anode Size (mm) 25 x 500 25 x 1000 32 x 1220 25 x 500 25 x 1000 32 x 1220 Current Output (Amps) 4 8 12 25 50 75 Lifetime (Years) 20 20 20 20 20 20 Availability [email protected] www.ctsonline.com Azerbaijan l Bahrain l Georgia l India l Kingdom of Saudi Arabia l Qatar l United Arab Emirates l United Kingdom l Malaysia
