Materials Required

MMO Titanium Ribbon Anode

Titanium Conductor Bar

Reference Cells and #14 awg yellow RHW Cables

Positive #8 awg black HMWPE Cable Connections

Titanium Spot Welder

Procedure

The under tank catholic protection system materials are to be installed during the construction of the

foundation. The ribbon anode, conductor bar, positive connection cables and reference cells are tobe installed a minimum of 4 below the final tank base plate level in river washed sand. The systemoperates better at a depth of 6 and may be installed up to 12 below the base plate.

Where there is a secondary containment liner, be it Claymax, HDPE or similar, the cathodicprotection system may be installed directly on top of the liner. The foundation sand material is thenplaced over the top of the CP Tank system.

Alternatively the foundation sand may be prepared and compacted to a level at which the CP tanksystem is to be installed. It is possible to bury the system in the foundation, or simply lay it on topof the sand. After installation of the CP Tank System the foundation contractor should carefully addand compact more sand until the final level is reached.

The Ribbon anode is supplied in rolls of approximately 330 length. The Conductor Bar is suppliedin rolls of approximately 330 length. Note that both the ribbon anode and the conductor bar can betwisted and do not need to be laid perfectly flat. If the system is being installed on a liner it isrequired to twist the ribbon to stop the ribbon lying flat on the liner and so to allow both faces of theribbon better contact with the foundation sand.

A minimum of two men are required to lay out the Ribbon anode and conductor bar. Two more menare required to spot weld the ribbon / conductor bar intersections. A measuring wheel (feet) andsome spray paint are useful to assist in marking out the system.

Mark the center of the tank. Pick a tank north direction. For the purposes of this instruction the anode ribbon will be assumed to run east / west and

the conductor bar north / south. Note there is an additional conductor bar through the centerin the east / west direction.

Using the wheel and spray paint, start at the center of the tank moving in the northerly directionand mark the first east / west ribbon run 2.5 feet from the center and at 5 foot intervalsthereafter.

From the center moving in the southerly direction mark the first east / west Ribbon run 2.5 feetfrom the center and thereafter at 5 foot intervals.


12/21

Job 2922


At the center mark the first conductor bar run north / south through thecenter.

Mark the east / west conductor bar run through the center. Mark the additional north / south conductor bar runs at 20 spacing each side (east and west) of

the center as shown on the drawing.

Mark the ribbon spacing at 2 more locations 25 feet either side of the diametric north south line.This provides three spray marks to lay out the anode ribbon in the correctly spaced straight line. Lay out the anode ribbon on the east / west lines at 5 foot centers. The ends of the ribbon

should be cut so that they are within 1 foot of the perimeter of the tank. Lay the conductor bar run in the east / west direction through the center. Lay out the conductor bar runs in the north / south direction through the center and at 20 foot

spacing each side. Spot weld the conductor bar and ribbon once (or twice) at every intersection. Weld the conductor bar / conductor bar crossings a minimum of twice at each intersection. Spot weld (a minimum of three welds) the titanium bar at one end of the positive cable

connections to the conductor bars at the center and at two more locations either side of center atthe conductor bar / conductor bar intersections as shown on the drawing.

Install the reference cells at the desired locations (one cell should be placed at the center of the

tank). Excavate a 6 deep hole in which to place the cells if in sand Remove the cells from the plastic shipping bags and discard the bags. Soak the cells with water (use 5 gallons of clean, fresh water) and bury them. All the power feeds and reference cell cables should be marked and laid across the tank, as

directly as possible to the exit conduit in the ring wall. All wires should be coiled and placed in a protected position outside the ring wall for

termination in the junction box at a later date. Extreme care must be taken to prevent metal to metal contact between the anode ribbon /

conductor bar and the tank metal bottom, sides or sump.

Subsequent to the construction of the tank, the junction box and rectifier will be installed and allwires connected and terminated.

Please refer to the drawings of the wiring required,Drawings #2922-001, 2922-002, 2922-003 and 292-004 apply.

The negative connection to the tank shell may be made at an earthing lug welded to the tanks close to

the junction box location or the cable may be Cadwelded to the bottom plate outside the shell.

Titanium Ribbon Anode and Conductor Bar

Titanium ribbon anodes are manufactured using ASTM B265 Grade 1 titanium which is coated with

Mixed Metal Oxide Coating. The MMO coating consists of IrO2/TA2O5and is suitable for use in all

cathodic protection applications.

Mixed metal oxide anodes have an extremely low consumption rate. The titanium substrate remains

constant throughout the design life of the anode.

Strict quality control procedures applied during the coating process to ensure proper coating

adhesion and loading. Production of a quality product is fundamental in every step of the

manufacturing process.

Current Output in FINE SAND: 5 mA/ft operating at an anode current density of 1.2 A/m2

Design Life: >50 years operating at an anode current density of 1.2 mA/m

High Molecular Weight Polyethylene Cable

The cable in cathodic protection systems is a critical component. CEM provides cable manufactured

specifically for cathodic protection applications from a variety of cable manufacturers. The industry

standard cable for direct burial is a stranded copper conductor covered with an insulation of highmolecular weight polyethylene (HMWPE). The thick, tough, insulation provides both electric

isolation and mechanical protection. During installation, this cable can withstand considerablemechanical abuse without compromising the conductor. The HMWPE insulation is chemically

resistant and protects against most organic and inorganic substances.

Application:

A direct earth burial DC feeder cable for use in cathodic protection systems, for storage

tanks, pipelines, wells, vessels and metallic structures either buried or water submerged.

Standards:Conductor - Stranded copper conductor conforms to ASTM Specification B-8.Insulation - Insulation is high molecular weight polyethylene conforming to ASTM D-1248, Type 1, Class A, Category 5, Grades E4 & E5. Tensile Strengths Jl, J3. Available withhigh density polyethylene (Types II, III, IV) Class B & C (all colors).

Permanent Reference Electrodes for Chlor ide Free Soils

NEW! Moisture Retention Membrane - MRM

Features

Minimum 20 year service life.

8 square inches of sensing surface area gives 5-8times more surface area than other electrodes.

This makes electrode positioning less critical to

achieve accurate readings.

Will not dry out in desert dry soil, a condition

that renders other electrodes ineffective. Cyclical variations in soil conditions, rangingfrom hydrated to dehydrated, have no adverse effect on the Stelth2 electrode.

Electrodes may be taken out of service for extended periods of time and reintroducedinto the system without affecting electrode accuracy or ability to reactivate. (Electrode

will fire up in less than 5 minutes.)

New! Now two levels of chloride ion trapping technologies are used in the "Stelth 2".FirstWe impregnate a trapping material into the ceramic sensing tube that traps chloride

ions before they reach the chemistry of the "Stelth 2" (patent pending).

SecondWe employ a chloride ion trapping system that removes chloride ions that penetrate theCuSO4 chemistry of the "Stelth 2" before these ions can cause damage. Both of these systems have

given an additional benefit of lowering the internal resistance of the "Stelth 2" reference electrode.NoteChlorides at levels of only 200 parts per million alter the chemistry of a Cu-CuSO4 referenceelectrode enough to cause a complete breakdown, resulting in loss of stability and finally a total

shutdown.

includes choosing an electrical junction box, which isbest suited for a particular corrosion prevention

application. Because there are so many unique

applications for cathodic protection, We offer custom

junction boxes that are made according to designspecifications. A custom junction box can be

manufactured according to operating parameters, or to

exact design specifications.

CP Tank junction boxes are installed at the tank andwill allow termination of the following cables

Anode positive connection cables
