Why Tanks Corrode
Underground steel tanks corrode due to an electrochemical reaction
between the tank and the surrounding soil. The process of corrosion
occurs due to small voltage differences on the steel surface that result
in the flow of DC current from one location to another. Where current
flows from the tank into the soil corrosion occurs. this location is called
the anode in a corrosion circuit. Where curientflows from the soil to the
tank, no corrosion occurs. The progress of corrosion is determined by
the amount of current flowing between the anode and the cathode and
whether the locations of the anode/ cathode, remain constant over time.
Corrosion rates are generally higher in wet soil environments since the
conductivity of the soil promotes the flow of DC current in the corrosion
circuit.
Corrosion generally exhibits itself on underground tanks in either a
general overall rusting or more commonly, a pitting attack. Pit locations
may result from metallurgical conditions of the steel suraface or soil
variations such as rocks, salts, fertilizer, moisture concentration, oxygen
concentration, etc.
Y p Preventing Corrosion
_ Protecting underground
larks from corrosion is
easily achieved by the use
of two commonly applied
• �„ protection methods:
external coating and
s 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 tine soil environment, thus preventing
the flow of corrosion current from the anode to the cathode. An effective
external coating can protect over 99% of the tanksurface area. However,
no coating is perfect. Damage from construction or soil stresses create
tiny defects, which may result in accelerated corrosion at the defect.
Cathodic protection prevents corrosion at those defects by applying
DC current from an external source, forcing the tank to become
cathode. Application of sufficient DC current to the tank will prevent any
corrosion from occurring. The two general types of cathodic protection
systems are sacrificial and impressed current. Sacrificial systems are
used when the amount of current required for the protection is small,
such as in underground propane tanks. Impressed current systems
are more commonly used for large structures such as large diameter
pipelines. Electrical isolation of the tank frorn metallic piping systems
and electrical grounds is critical for the cathodic protection system's
effectiveness.
How Sacrificial Cathodic Protection Works
Sacrificial 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 inetals 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 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
Lip 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 TIN insulated wire is attached to the anodes. Anodes are
then backfilled 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 recommendationsforvarious size tanks based
on conservative design assumptions. This chart covers soil conditions
up to 10,000 ohm -centimeter resistivity. Resistivities higher than
10,000 olrm-centimeter generally represent very dry soils. Verification
of soil resistivity can be performed through soil analysis. Contact us
for design recommendations In locations where soil resistivities exceed
10,000 ohrn-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 sufficient current
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. Copper and steel create a galvanic couple thatwill accelerate
corrosion of the steel tank when directly connected to copper piping.
Generally, copper piping does not require cathodic protection.

Anode Installation
1. Determine size and quantity of anodes from application chart.
2. When a single anode is installed, it should be located near the
tank center on either side of tank.
3.When multiple anodes are installed, space them evenly around
the tank. See examples below.
1 anode 2 anodes F 4 anodes
4.Anodes are shipped in either cardboard boxes or multi -wall
paper sacks. Remove outer container and bury the cloth bagged
anode. If anode is supplied in plastic bag, remove plastic, bag
before installing.
5. Install anodes approximately two to three feet from tine tank and
at least as deep as the centerline of the tank. Anodes work best
in locations with permanent moisture, so generally the deeper
the better.
6.After placing the anode, stretch out the anode connection wire
and extend over to a connection point on the tank fill pipe.
7. Cover the anode with approximately six inches of backfill and
pour 5 gallons of water on the anode to saturate the prepared
backfill. Water is necessary to activate the anode.
8. Connect tine anode wire to tine tank with a low electrical
resistance connection. Examples are threaded stud on the
tank fill pipe or any accessible metallic connection point to the
tank. All connections should be coated with a moisture -proof
material.
9.Ideally, the tank connection is made in the area of the tank fill
pipe within the covered dome. With access to the anode wire,
subsequent testing of tine tank can include measurement of
anode output and verification of performance.
10.Verify performance of tine anode using an appropriate test
procedure.

Cathodic Protection Testing Procedure
Equipment Needed: Digital Voltmeter, Red Test Lead Min,12' Long
& Black Lead Min. 2' Long, Reference Electrode (Copper/Copper
Sulphate Half -Cell)
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 to a charged reference
electrode (%cell).
STEP 3: Remove protective cap from the porous plug at bottom end
of electrode. Place porous plug end into native soil (remove grass if
necessary) at four locations around the tank (one on each side of the
tank, and one at each end of the tank). If difficulty is encountered
obtaining readings, moisten soil with water or diig'/z 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 deionized 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 bottom of
the tube. DO NOT USE TAP WATER.
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; This will allow the porous plug
to become completely saturated before use.
Caution: Do not allow electrode to contact oil, road salts, or other
substances that may contaminate the solution by absorption
through porous plug. Do not al/Olt, electrode to freeze.
