MMO titanium tubular anode connect with XLPE/PVC or PVDF/HMWPE cable
The anodes are made using tubular 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.

Cable and Centralisers
Cable sizes ranging from 6mm² to 50mm², depending on the tube diameter, are available. The cable can be supplied with an insulation of XPLE/PVC, or EPR/CSPE or Kynar/HMWPE.
Anode strings are supplied either with a single or double tail. Centralisers and bottom weights are also available as standard items.
3.Applications
Mixed metal oxide anodes have proven to operate effectively in all types of environments including areas with extremely low pH levels under 1, and high chloride concentrations. While Corrpro tubular anodes can be used singularly, their unique configuration also makes them ideal for use in strings on offshore platforms or in deep groundbeds. In addition, the string anodes can be installed parallel to transmission pipelines or used for other special applications.
4.Installation
They are available as a single-unit assembly, or as a multi-unit assembly on a single cable. Taijin wire or tubular anodes are also available as canistered anodes, surrounded by carbonaeous backfill to minimize installation time and handling on site. Taijin mixed metal oxide anodes are also available in wire, rod, mesh, ribbon, and disc form for a variety of impressed current CP applications.
The tubular design of these anodes also allows for numerous performance benefits. The tubular configuration provides a larger surface area which in turn permits greater current output and lower anode-to earth resistance. The tubular style also means lead wire connections can be made in the center of the anode. With Corrpro tubular anodes, this connection consists of a brass wedge connector which grips firmly to the internal circumference of the anode. This connection is protected from moisture intrusion by a waterproofing sealant which fills the entire anode tube. One end of the anode is then covered with shrink tubing for a completely sealed electrical connection. Anodes are then tested for quality assurance.
