MMO titanium tubular anode is widely used in the cathodic protection field, base material is ASTM B338 titanium tube with outside diameter of 19mm/25mm and 32mm, among them 25mm is the most needed by the market. coating material can be RuO2+IrO2+X or IrO2+Ta2O5+X according to the application environment.
MMO titanium tubular anode is the main parts of the canistered anode, which is composed of MMO titanium tubular anode strings, air ducts, coke fillers and steel sleeves. The noble mixed metal oxide(MMO) titanium tubular anode strings (generally composed of 3 anodes with size is OD.25mm*L) are fixed in the center of the steel sleeve, and installed Coke packing is filled around the anode string after the gas duct.
Canistered anode body: medium 219×6000 (including 3-4pcs OD.25×1000mm MMO titanium tubular anodes) Canistered anode body: 219×4000 (including 2pcs OD. 25×1000mm MMO titanium tubular anode) It has the advantages of long service life, convenient installation and small grounding resistance. The successful development of this anode body has greatly shortened the construction period of the project, and at the same time effectively guaranteed the construction quality of the key part of the cathodic protection system—the anode bed.
