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 be

installed 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 wire shaped 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.

REVISION 1

APPLICATION

HALAR/HMWPE cable is designed for anode lead wires in a wide range of environments. Due to its dual insulation construction, it can be installed directly in native soils or submerged in fresh, brackish, or salt waters. The cable is ideal for 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 temperatures up 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 where brackish water is present in the ground. In this environment, anodes generate reactive gases such as chlorine and nacent 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. HALAR fluoropolymer is inert to reactive compounds and has an outstanding ability to prevent the passage of gases. Laboratory and field evaluations indicate that HALAR fluoropolymer insulated lead wire can extend the life of deep anode

installations. The cable is composed of stranded copper wire covered by two layers of insulation. The outer insulation layer is made from high molecular weight polyethylene (HMWPE). It exhibits superior dielectric and tensile strength, and provides 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 chemical resistance. In the presence of chlorine, hydrochloric acid, sulfuric acid, or other strong oxidizing agents the material remains stable. Further, it will not deteriorate when exposed to petroleum hydrocarbons which are encountered in numerous cathodic protection applications.

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

In remote areas, providing AC power for impressed current cathodic protection systems can be a major constraint. Solar electricity is a solution to this problem.

Solar generators provide a reliable and low maintenance source of power that can be used for cathodic protection.

The control equipment is an integral part to the reliability and performance of the Solar generator. We use world leaders in the design, manufacture and supply of

these controls to cover an extensive range of requirements. The CP controller utilises high-speed pulse width modulated switching technology to ensure the highest conversion efficiency fully maximising the power from the SGU.

The controller which is a DC-DC converter is suitable for connection to 12, 24 or 48Volt DC systems with output current options of 25A and 50A. The controller is capable of controlling the power delivered to the load to a maximum of 1V below

the input voltage.
