TECHNICAL DATA SHEETTAIJIN TUBULAR ANODES FOR CATHODIC PROTECTION TAIJIN MMO Canister Anode is titanium tubes with a mixed metal oxide coating. The mixed metal oxide is a crystalline, electrically conductive coating that activates the titanium and enables it to function as an anode.TAIJIN MMO Canister Anode is available in optional metal canisters for installation where conventional hole loading methods may not be practical. TAIJIN anode canister assemblies are made from galvanized steel. The assembly includes calcined petroleum coke breeze backfill (several choices are available), an anode centering device, galvanized steel end plugs , and a lifting bail to ease installation.TAIJIN utilizes a galvanized steel end plug as opposed to a plywood end plug. Doing so ensures that the end plug will not split and that the coke breeze backfill is sealed inside the canister.1.SubstrateTitanium ASTM B 338 Grade 11)Chemical Composition
