MMO/Ti Flexible anode

MMO/Ti Flexible anode(MMO Ti Linear Anode)

MMO linear anodes are a flexible, prepackaged porous, woven acid-resistant sleeve linear anode contains high conductivity calcined petroleum coke breeze. This sleeve is sewn using a poly two or four-thread double interlocking stitch, which prevents the seam from separating during installation, or when stored in high temperature conditions. This arrangement avoids handling loose coke breeze and simplifies field installation. It improved current distribution increases anode efficiency and helps prevent over-voltage problems such as hydrogen generation and associated rapid coating disbondment. In addition, interference from other structures and stray currents are virtually eliminated.

UTron develops and manufactures MMO linear anode for cathodic protection by adopting Gr1 or Gr2 titanium wire (ASTM B348) in 1, 5 mm or 3mm diameter with MMO (IrO 2 /Ta 2 O 5) catalyst coating. This MMO linear anode is proved to be efficient in low-current, distributed cathodic protection systems.
