PLATINISED TITANIUM ANODES


REVISION 1




DATASHEET2.3.3

APPLICATION

• Underwater steel structures - Wharves, jetties, sheet pile walls and piers. Usually rod type anodes distributed throughout the structure to be protected to give a good overall protective current distribution. Anodes should beinstalled in areas not liable to cause Anode damage i.e. out of the way of berthing vessels, mooring ropes, chains etc.

• Exterior protection of ships hulls - anodes in the shape of plates, discs or strips. Housed in chlorine resistant plastic as the anode operates at high current densities in seawater which produces chlorine.

• Water tank internal protection - usually distributed rod anodes are used for this type of installation by suspending from the tank roof.

• Internal protection of plant - large diameter water pipelines such as cooling water can be protected using rod or wireshaped anodes.

PLATINISED TITANIUM ANODE DATA

Platinised Titanium anodes are manufactured from a commercially pure titanium substrate plated with a very thin coating

of platinum. The titanium serves simply as the anode body and the conductor, the active anode element being the

platinum coating.

The usual thickness of the platinum coating is approximately 2.5 microns, however, this coating thickness should be

increased to 5.0 microns for harsher environments. The base metal is available in a wide variety of standard shapes -

rods, tubes, mesh, etc - which can be fabricated into non-metallic mounts for attachment to the structure to be

cathodically protected.

The thickness of the platinum coating and the current density at which the anode is operated determine the useful life

of the anode. The maximum voltage at the anode to electrolyte interface should not exceed 8 Volts in electrolytes

containing chloride as voltages greater than this value could cause local corrosion on any unplatinised portions of

the anode.

Platinised titanium anodes should not be used in electrolytes containing fluoride as titanium oxide dissolves in fluoride.

Anodic passivation does not protect the titanium substrate in such electrolytes.

The advantage of platinised titanium anodes is that they can be operated at high current densities with very low

consumption rates.

CABLE HALAR/HMWPE


REVISION 1




DATASHEET2.6.6

APPLICATION

HALAR/HMWPE cable is designed for anode lead wires in a wide range of environments. Due to its dual insulationconstruction, it can be installed directly in native soils or submerged in fresh, brackish, or salt waters. The cable is idealfor deep anode bed installations where chlorine and hydrogen gases are generated. The HALAR insulation will not embrittle at temperatures down to (-80F) and will maintain dimensional stability and dielectric strength at temperaturesup to 250F. It is highly resistant to notch propagation.

One of the major causes of deep anode failures is the failure of cable insulation. This is especially evident in areas wherebrackish water is present in the ground. In this environment, anodes generate reactive gases such as chlorine andnacent oxygen. These gases cause rapid deterioration of conventional HMWPE insulation.

Cathodic protection cable insulated with HALAR fluoropolymer, is especially suited for deep anode lead wires. HALARfluoropolymer is inert to reactive compounds and has an outstanding ability to prevent the passage of gases. Laboratoryand field evaluations indicate that HALAR fluoropolymer insulated lead wire can extend the life of deep anodeinstallations. The cable is composed of stranded copper wire covered by two layers of insulation. The outer insulationlayer is made from high molecular weight polyethylene (HMWPE). It exhibits superior dielectric and tensile strength, andprovides mechanical protection to the cable.

The material is also resistant to water intrusion and is not affected by most organic or inorganic substances. The inner

or primary insulation is composed of HALAR, a fluoropolymer. This insulating material demonstrates exceptional chemicalresistance. In the presence of chlorine, hydrochloric acid, sulfuric acid, or other strong oxidizing agents the materialremains stable. Further, it will not deteriorate when exposed to petroleum hydrocarbons which are encountered innumerous cathodic protection applications.

The dual extrusion HALAR cable is made specifically for cathodic protection applications. It can withstand considerableabuse during installation.

Conductor : Stranded bare copper conductor conforms to ASTM Specification B-3 and B-8.

Insulation : A homogeneous wall of natural ECTFE fluoropolymer (HALAR) shall be extruded over the conductor.

Jacket : Insulation is high molecular weight polyethylene conforming to ASTM-D-1248, Type 1, Class C, Category 5,Grades E5 & J1. Tensile Strengths Jl, J3.

Available with high density polyethylene (Types II, III, IV) Class B and C (all colors). Surface printed. Custom printing available.
