Because
an oxidizing film naturally passivates the titanium substrate,
the Ti anode remains dimensionally stable over time. Direct
current transfer is accomplished through the mixed metal oxide
catalyst, which is highly conductive and fully oxidized so
that higher current outputs are possible (approximately 10
amps/ft2 in fresh water and over 50 amps/ft2 in salt water).
This two part composition allows for a maximum current density
and it can be used in sands with various levels of moisture
and salt contents, acid environments with extremely low pH
levels (under 1.0) and high chloride concentrations; It can
be designed to provide effective protection for 20 years and
more. i.e. the mixed metal oxide coating on the anodes has
an almost negligible consumption rate of less than 1.0mg/amp-yr.

Cathodic
protection is an economical method for controlling
corrosion on above ground storage tank bottoms, buried
and submerged structures, deep and conventional ground
beds and in fresh, brackish and salt water electrolytes,
offshore platforms, condensers, water tanks and pressure
vessels. We do design, fabrication
& supply of:
-
Mixed Metal Oxide Coated Titanium Ribbon, Probe,
Mesh, Wire, Strip, Disc, Tubular & Rod Anodes.
- Platinised
Niobium & Titanium Tubular, Wire, Mesh, Probe
& Strip Anodes.

Application
& Availability:
CPCC MMO titanium anodes perform well in all types of environment
including areas with extremely low pH level (under 1), and
high chloride concentrations. These unique configurations
makes the CPCC MMO anodes ideal for use in a wide variety
such as cathodic-protection system for buried structures,
pipeline, steel in concrete, ship, jetties & wharf. Following
standard / custom-made anodes are manufactured by TAF.

What
is CPCC MMO?
MMO or Platinised coating is an excellent Electrical conductor
and giving well chemical stability, when it will be coated
on Titanium or Niobium base, even in very low pH environments.
Major
Failure of Cathodic Protection systems are due to the break
down of the electrical connection between the cable joints
and anodes. These failures will take place, when the anodes
connections are jointed by resin based seals.
To
prevent such a failures, we developed the hybrid method of
"CPCC" cable joints by hot fusion crimping of anode
with the copper conductor, covered by polymer cable sheath.
After
the crimping, the joints are 100% Quality Assured on...

MMO
Coating & its Current out put:
MMO coating greatly prolong the life of the anode (low wear rate)
and provide excellent chemical corrosion resistance such as acid
condition. The standard outputs are as below. However, coating loading
may be adjusted to suit a particular current density or design life.
