The process of c occurs due to small voltage differences on the steel surface tf in the flow of DC current from one location to another. When flows from the tank into the $oil corrosion occurs. This location the anode in a corrosion circuit. Where current flows from the s tank, no corrosion occurs. The progress of corrosion is detern the amount of current flowing between the anode and the oath whether the locations of the anode/ cathode remain constant ov Corrosion rates are generally higher in wet soil environments si conductivity of the soil p circuit romotes the flow of DC current in the cc Corrosion generally exhibits itself on underground tanks In general overall rusting or more commonly, a pitting attack, Pit Ic may result from metallurgical conditions of the steel surface variations such as rocks, salts, fertilizer, moisture concentration, concentration, etc. Preventing: Corro Protecting undei tanks from corrc easily achieved by Of two commonly Protection mi µY 4s external coating cathodic prot These two mi are compiem and should be u( g conJunction with other.

Damage from construction or soil stresses c tiny defects, which may result in accelerated corrosion at the defec Cathodic protection prevents corrosion at those defects by appi DC current from an external source, forcing the tank to boo, cathode, Application of sufficient DC current to the tank will prevent corrosion from occurring. The two.general systems are sacrificlal and Impressed currents Sac ificialsystems used when the amount of current required for the protection is srr such as in underground propane tanks. Impressed current syste are more commonly used for large structures such as large dlam( pipelines. Electrical isolation of the tank from metallic piping systei and electrical grounds is critical for the cathodic p effectiveness. rotection syster How Sacrificial Cathodic Protection Works Sacrificial systems work by creating a galvanic connection between different metals. The most common anode material is magnesium, reaction which when coupled to steel results in. DC current flow from the Itros result magnesium to the steel. The open circuit potential of steel is about It result -6.50 volts referenced to a copper sulfate electrode. The open circuit current potential of magnesium is about -1.55V to-1.80V. By connecting the s called two metals together, the difference of 1 to 1.25V volts results in current q to the flow to the tank that overcomes the natural corrosion cells that exist on ned by the tank. With this current available to the tank, no corrosion occurs. de and rtime. Magnesium Anodes ice the There are a variety of anode sizes and alloys used for cathodic ros(on protection. The two primary alloys are designed as H-1 (or AZ63) and High Potential. The H-1 alloy is produced from recycled magnesium and has an open circuit potential of approximately—1.55V. This alloy ,her a Potential alloy is 99% pure magnesium having an open circuit is well suited for protection of underground propane, tanks. The Hi stions ghial potent r soil up to -1.8V. This alloy should be used for soil applications over 10,0 is (ygen ohm -cm resistivity. in The two most common anode sizes used for underground propane tanks are 9lb. and 171b.

The H-1 alloy is generally very effective. The following chart lve provides size and quantity recommendations for ive on conservative design assumptions. This chart covers soil conditions v9 up to 10,000 ohm -centimeter resistivity. Resistivities higher than ve 10,000 ohm -centimeter generally represent very dry soils. Verification �r. of soil resistivity can be performed through soil analysis. Contact us to for design recommendations in locations where $oli resistivitles exceed 10,000 ohm -cm, or if there is no effective external coating on the tank. 9 The propane service line from the tank to the house also must be e considered in the cathodic protection design, unless the service line y is plastic. All underground steel pipe should be externally coated with n a corrosion resistant material. The service fine should be electrically isolated at the house with an insulating fitting or union. If service pipe is less than 50' in length, the tank anodes will provide sufficient current I to protect both tank and pipe. For longer lengths of pipe, an additional anode may be required at the house connections. if another metallic material such as copper is used for service piping, the pipe should be electrically Isolated from the tank at the fill pipe connection. Copperand steel create a galvanic couple that will accelerate corrosion of the steel tank when directly connected to copper piping., Generally, copper piping does not require cathodic protection.

Connect the anode wire to the tank with a low elect resistance connection. Examples are threaded stud one tank fill pipe or any accessible metallic connection point to tank.

If difficulty Is encountered obtaining readings, moisten soil with water or dig Y2 cell deeper into the soil. STEP 4: Record all four'meter readings on an appropriate form. The least of all four readings should be a minimum of-0,850v or more negative. {Note: If any of the four readings are below (less negative) -0,850v then the tank is not fully protected), "O1 Charging Reference Electrode wire STEP 1: Unscrew and remove porous plug end of new reference and electrode.
