Mixed Metal Oxide Anodes
Mixed Metal Oxide Tubular Anodes
To obtain the highest level of protection from an
impressed current cathodic protection system, you
need an anode with a very low consumption rate and
high current capacity. With Corrpro’s tubular mixed
metal oxide line of anodes, you get powerful protection
and unsurpassed stability.
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.
In soil and fresh water applications,
the anodes have a recommended current density of
approximately 10 amp/ft2, and can be operated over
50 amp/ft2 in sea water environments. Even at these
relatively high discharge levels, the anodes will be
consumed at less than 1.0 mg/amp-yr.
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.
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.

Ordering Procedure
Corrpro tubular mixed metal oxide anodes are available
in several different dimensions. To order the required
anode for your structure, indicate that you need a
tubular mixed metal oxide anode. Specify the quantity
desired, the anode type, the lead wire length, size,
insulation and whether it should be packaged or bare.
