The process of corrosion occuue to small voltage differences on the steel surface that result In thw of DC current from one location to another. Where current flows, rom the tank into the soil corrosion occurs. This location is called the an de in a corrosion circuit. Where current flows from the soil to the tank, o corrosion occurs. The progress of corrosion is determined by the an ount of current flowing between the anode and the cathode and wheth r the locations of the anode/ cathode remain constant over time. Corro, on rates are generally higher in wet soil environments since the condui tivity of the soil promotes the flow of DC current in the corrosion uorro on generally exhibits itself on underground tanks in either a gonerIn' overall rusting or more commonly, a pitting attack. Pit locations may rslt from metallurgical conditions of the steel surface or soil variatis such as rocks, salts, fertilizer, moisture concentration, oxygen conceration, etc. r Preventing Corrosion Protecting underground tanks from corrosion is easily achieved by the use of two commonly applied protection methods: external coating and .• cathodic protection. These two methods are complementary and should be used In conjunction ' with the other. An effective external protective coating insulates the steel from the soil environment, thus preventing the floW of corrosion current from the anode to the cathode. An effective extema coating can.protect over 99% of the tank surface area. However, no coatrig Is perfect. Damage from construction or soil stresses create tiny def cts, which may result in accelerated corrosion at the defect. cathodi protection prevents corrosion at those defects by applying DC cur ent from an external source, forcing the tank to become cathode Application of sufficient DC current to the tank will prevent any corros( from occurring. The two general types of cathodic protection system are sacrificial and impressed current. Sacrificial systems are used wl on the amount of current required for the protection is small, such as in underground propane tanks. Impressed current systems are mor commonly used for large structures such as large diameter pipeline, . Electrical isolation of the tank from metallic piping systems and ele rical grounds is critical for the cathodic protection system's u....u.." -"- How ft riticial Cathodic Protection Works Sacrifici I systems work by creating a galvanic connection between two different metals. The most common anode material is magnesium, which when coupled. to steel results in DC current flow from the magnesium to the steel. The open circuit potential of steel is about -0.50 volts referenced to a copper sulfate electrode. The open circuit potential of magnesium is about -1.55V to-1.80V. By connecting the two metals together, the difference of 1 to 1.25V volts results in current flow to the tank that overcomes the natural corrosion cells that exist on the tank. With this current available to the tank, no corrosion occurs. Magnesium Anodes There are a variety of anode sizes and alloys used for j cathodic 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 is well suited for protection of underground propane tanks. The High Potential alloy is 99% pure magnesium having an open circuit potential up to -1.8V. This alloy should be used for soil applications over 10,000 ohm -cm resistivity. The two most common anode sizes used for underground! propane tanks are 9lb. and 171b. The size designation relates to the metal weight. 10' of #12 TW Insulated wire is attached to the anodes. Anodes are then backfiiled in a mixture of gypsum, bentonite, and sodium sulfate to lower the electrical resistance of the anode to soil. The mixture is a low cost, nonhazardous, electrically conductive backfill. The anode and backfill is then packaged in a cotton bag and either a cardboard box or paper bag. Actual shipping weight of these anodes with backfill is 27 lb. and 45 lb. Application Recommendations Magnesium anodes can protect underground tanks in most soil conditions. The H-1 alloy is generally very effective. The following chart provides size and quantity recommendations for various size tanks based on conservative design assumptions. This chart covers soil conditions up to 10,000 ohm -centimeter resistivity. Resistivities higher than 10,000 ohm -centimeter generally represent very dry soils. Versification of soil resistivity can be performed through soil analysis. Contact us for design recommendations in locations where soil resistivities exceed 10,000 ohm -cm, or if there is no effective external coating on the tank. The propane. service line from the tank to the house also must be considered in the cathodic protection design, unless the service line Is plastic. All underground steel pipe should .be externally coated with a corrosion resistant material. The service line 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 sufficienticurrent 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 fIII pipe connection. Copper and 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. yearAi Anode 1. DE 2. WI 3. Wt the 4. 5. Insta at lea In Io( the bi 6. After and e; 7. Cover pour; 8. Connet resistar tank fill tank.

Equipment Needed: Digital Voltmeter, Red Test Lead Min.12' Su pha a Half --Cell) 2' Long, Reference Electrode (Copper/Copper STEP 1: Using a digital voltmeter insert the red test lead Into the Volt jack of the meter and select the 2 or 20 volt DC scale. Clip red test lead connector to an uncoated metallic area of the tank, preferably to the fill pipe multivalve. A good solid connection is very Important. (DO NOT connect to shroud). STEP 2: Insertthe black test lead Into the Common jack on the meter, and connect the opposite end of the lead electrode (Y2 cell). to a charged reference STEP 3: Remove protective cap from the porous plug at bottom and of electrode. Place porous plug end Into native soil (remove grass if necessary) at four locations around the tank (one on each side bf the tank, and one at each end of the tank). If difficulty is encountered obtaining readings, moisten soil with water or dig Yz 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). Charging Reference Electrode STEP 1: Unscrew and remove porous plug end of new reference electrode. Add delonized or distilled water to the copper sulfate crystals, filling electrode completely. The solution will turn blue in color and there should always be excess crystals at the botto the tube. DO NOT USE TAP WATER. m of STEP 2: Replace porous plug end of electrode and place In an upright Position so that the porous plug end Is facing In the down position and let stand for 1 hour before use.
