APPLICATION Horizontal Groundbeds, Shallow Vertical Groundbeds.
STANDARD ANODE TYPES, DIMENSIONS AND OUTPUTS
MESH STRIP ANODES are manufactured using titanium expanded mesh substrate, which meets ASTM B265 Grade 1 or 2 standards
MESH STRIP ANODES are 1.25" wide x 48" long and are rated 5 Amps for a 20 year design life in calcined petroleum coke. The MESH STRIP ANODE can be packaged in a spiral wound, galvanized steel canister or a fabric sleeve. Anode size and rating is calculated as follows, • Max Operating current density of anode = 100A/m 2 • Titanium Surface Area of 1.25” (32mm) Width x 48” (1220mm) Length Strip Mesh Anode = 0.05m 2 • Titanium is coated with a proprietary MMO coating with a sufficient loading to last a minimum of 20 years at the specified current density. • Surface area of anode is 0.05m2 and at current density of 100mA/m 2 gives output 5A for minimum 20 years (or equivalent of 100 Amp/years at max current density of 100A/m 2)
CABLE TYPES & CONNECTIONS Anodes are factory assembled with a fully encapsulated cable connection. Method of Connection : A stud bolt is passed through the mesh onto which a suitably sized cable lug is placed and then tightened with nuts and steel washers to create an electrical connection between mesh anode and cable. Electrical resistance test performed : Maximum connection resistance of 0.001 Ohm Connection encapsulated with heat shrink sleeve

GRAPHITE ANODES REVISION 1 APPLICATION Plain graphite anodes are used in dry soil conditions installed in groundbeds containing compacted carbonaceous backfill. Linseed oil impregnated anodes can be used in moist saline soils, in fresh and brackish water, and for seawater applications. Graphite anodes can be installed as horizontal or deepwell groundbeds to protect buried pipelines or due to their lightweight nature they can be suspended into the electrolyte to protect water tank internal surfaces or marine structures.
GRAPHITE ANODE DATA
Cathodic Protection Co Ltd graphite anodes are manufactured in two standard sizes - 3” dia up to 60” long & 4” dia up to 80” long. There are two types of graphite anodes - plain & linseed oil impregnated. Plain graphite anodes are used for ordinary soil conditions and linseed oil impregnated anodes are usually used for saline soil or seawater environments.

PLATINISED TITANIUM ANODES REVISION 1 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. 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 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.
HALAR/HMWPE CABLE DATA
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.
STANDARDS 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.
