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 current flows 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 surface or soil
variations such as rocks, salts, fertilizer, moisture concentration, oxygen
concentration, ate.
Preventing Corrosion
Protecting underground
` tanks from corrosion is
easilyachfevedbytheuse
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
external coating can protect over99% of the tank surface area. However;
no coating is perfect. Damage from construction or soil stresses create
tiny defects, which may result in accelerated corrosion atthe 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 from 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 metals together the difference of 1 to 1.25Vvoits 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 allay is 99%1 pure magnesium having an open circuit potential
up to-11.8V. 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 j lb. and 171b. The size designation relates to the metal weight.
10' of #,12 TIN insulated wire is attached to the anodes. Anodes are
then backflled in a mixture of gypsum, hentonite, and sodium sulfate
to lowerith'e 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 generallyveryeffective. 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. Resistiviiies higher than
10,000 ohm-centimeterigenerally represent very dry soils. Verification
of soil resistivity can be performed through soil analysis. Contact us
for designrecommendations 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' fn length, the tank anodes will provide sufficient current
to protect bothtank 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 couplethatiMll accelerate
corrosion of the steel tank when directly connected to copper piping.
Generally, copper piping does not require cathodic protection.

Anode Inslallation
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 In
4.anodes
4.Anodes are shipped In either cardboard boxes or multi -wall
paper sacks. Remove outer container and burythe cloth bagged
anode. If anode is supplied In plastic bag, remove plastic bag
before Installing.
5. Install anodes approximately two to three feet from the tank and
at least as deep as the center line 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 overto a connection point on the tankfiil 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.
B.Connect the anode wire to the 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 the tank can include measurement of
anode output and verification of performance.
10.Verify performance of the anode using an appropriate test
procedure.

Sulpf;ate Half-Cell)1
STEP9�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 flle�flll pipe multivalve. A good solid connection Is very important.
(DO NOTconnectto shroud).
STEP 2:Ilnsertthe b�lacktest lead Into the Common jack on the meter,
ands connect the opposite end of the lead to a charged reference
electrod'ei(h cell). I
STEP 3:ftemove protective cap from the porous plug at bottom and
of electrode. Place porous plug end into native soil (remove grass if
necessary) atfour locations around the tank (one on each side of the
tank, and;one at each end of the tank). If difficulty is encountered
obtafning readings, Moisten soil with water or dig � cell deeper into
the soil. I
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 j {Note: If any of the four readings are below (less negative)
-0.850v then the tank is not fully protected}.
Reference Electrode
STEP 1: Unscrew and remove porous plug and of new reference
electrode[ Add deionized or distilled water to the copper sulfate
crystals, filling electrode completely. The solution will turn blue In
mlor'and there should always be excess crystals at the bottom of
the tube. I DO NOT USE TAP WATER.
3TEP:2 Replace porous plug end of electrode and place in an upright
iositiori sd that the porous plug end Is facing in the down position
nd let Wrid for 1 hour before use. This will allow the porous plug
o become completely saturated before use.

Freeze-up inside the regulator.
This will prevent the regulator from regulating properly.
Regulator freeze -ups occur because there Is excessive moisture
In the gas. Freeze -ups can also occur in pigtalis that are kinked or
bent where free flow of the LP -Gas is restricted. These freeze�ups
can occur when the moisture, gas flow and temperature combine to
create a hazardous condition. Freeze -ups can occur at temperatures
above 32°F.
Action Required: All LP -Gas should be checked for moisture content
prior to delivery to consumers and proper amounts of anhydrous
methanol added if the gas cannot be returned to the supplier. Any
container suspected of having excessive moisture should be treated
with the proper amount of methanol.
Customer Safety
Since regulators are often used by consumers without previous
knowledge of the hazards of LP -Gas, and the LP -Gas dealers are the
only ones who have direct contact with the consumers,
It Is the dealer's responsibility to make sure that his
customers are properly Instructed In safety matters relating
to their Installation.
At the very minimum, it Is desirable that these customers:
1. Know the odor of LP -Gas and what to do in case they smell
gas. Use the NPGA "Scratch 'n Sniff' leaflet.
2. Are Instructed to never tamper with the system.
3. Know that when protective hoods are used to enclose
regulators andlor valves, that these hoods must be closed,
but not locked.
4. Keep snow drifts from covering regulators.
S. Know the location of the cylinder or tank shut-off valve in
emergencies.
Und" ' round 1 1 tallatioris
Speclat hazards can occur If regulators are not properly Installed in
underground systems. Water, dirt, mud and insects can get into the
regulator if the bonnet cap Is not lightly In place and the vent Is not
protected with a proper vent tube, opening above any potential water
Most problems occur because the waterproof dome on the burled
stonade tank does not extend above the ground level sufficlently to
keep out water and mud.

All RegO Products are mechanical devices that will eventually
become inoperative due to wear, contaminants, corrosion
and aging of components made of materials such as metal
anti rlibber. As a general recommendation,Regulators should
be replaced In accordance with all of the recommendations
outlined In this safety warning. The recommended service
life lof a regulator is one of many factors -that must be
ci nmWered in determining when to replace a regulator.
The environment and conditions of use will determine the safe
service life of these'products. Periodic Inspection and maintenance
are essential.
Because RegO Products have a long and proven record of quality
and service, LP-Ges dealers may forget the hazards that can occur
becauseia regulator Is head beyond Its safe service life. Life of a
regulator, is determined by the environment in which It 'lives.' The
LP -Gas dealer knows better than anyone what this environment is.
NOTE:There is aIdeveloping trend In state legislation and
in proposed national legislation to make the owners of products
responsible for replacing products before they reach the and of their
safe useful life. LP -Gas dealers should be aware of legislation which
could affect them. 1

First Stage Regulator
with Relief Valve and
—: a regulator is truly the heart of an LP -Gas installation. It must
-_—pensate for variations in tank pressure from as low as 8 PSIG
220 PSIG — and still deliver a steady flow of LP -Gas at 11" w.c.
= consuming appliances. The regulator must deliver this pressure
to a variable load from intermittent use of the appliances.
�-tgh a single -stage system may perform adequately in many
:;afions, the use of a two -stage system offers the ultimate in pin-
-`-t regulation. Two -stage regulation can result In a more profitable
=-Gas operation for the dealer resulting from less maintenance and
e er installation callbacks — and there is no better time than now for
=tailing RegO Regulators in two -stage systems.
sniform Appliance Pressure
i s installation of a two -stage system — one high pressure regulator
at the container to compensate for varied inlet pressures, and one
c:r pressure regulator at the building to supply a constant delivery
;mssure to the appliances — helps ensure maximum efficiency
a- d trouble -free operation year-round. It is important to note that
r:^le pressure at the appliances can vary up to 4" w.c, using single -
stage systems, two -stage systems keep pressure variations within
?' w.c. New high -efficiency appliances require this closer pressure
control for proper ignition and stable, efficient operation. In fact, one
sal.or manufacturer requires the use of two -stage systems with their
appliances.
Reduced Freeze-ups/Service Calls
Regulator freeze-up occurs when moisture in the gas condenses and
freezes on cold surfaces of the regulator nozzle. The nozzle becomes
chilled when high pressure gas expands across It Into the regulator
body. This chilling action is more severe in single -stage systems as
gas expands from tank pressure to 11' w.c. through a single regulator
nozzle.
Size The System Correctiy
Prior to installing your two -stage system, be sure the system pipe
and tubing Is properly sized. Proper sizing will help ensure constant
delivery pressure to the appliances during fluctuating loads at all
times. Just as Important, be sure the RegO Regulators you choose
are capable of handling the desired load. This is another advantage
of two -stage systems — they are capable of handling much
more BTU's/hr. than single -stage systems. The RegO `LP -Gas
Serviceman's Manual" provides complete Information on pipe sizing
and proper regulator selection.
'Two -stage systems can greatly reduce the possibility of freeze -ups
'and resulting service calls as the expansion of gas from tank pressure
Ito 11" w.c. is divided into two steps, with less chilling effect at each
'regulator. In addition, after the gas exits the first -stage regulator and
;enters the first -stage transmission line, it picks up heat from the line,
further reducing the possibility of second -stage freeze-up.
:Service calls for pilot outages and electronic Ignition system failures
are also reduced as a result of more uniform appliance pressure from
two -stage systems.
Economy of Installation
In;a single -stage system• transmission line piping between the
container and the appliances must be large enough to accommodate
the required volume of gas at 11' w.c. In contrast, the line between
the first and second stage regulators In two -stage systems can be
much smaller as it delivers gas at 10 PSIG to the second -stage
regulator. Often the savings in piping cost will pay for the second
regulator.
As, an additional benefit, single -stage systems can be easily
converted to two -stage systems using existing supply lines when they
prove Inadequate to meet added loads. This is the least expensive
and best method of correcting the problem.
Allowance for Future Appliances
i
A h'igh degree of flexibility is offered in new installations of two -
stage systems. Appliances can be added later to the present load —
pioylded the high pressure regulator can handle the Increase — by the
addition of a second low pressure regulator. Since appliances can be
regulated Independently, demands from other parts of the installation
will not affect their individual performances.
Replace Pigtails
If you are replacing an old regulator, remember to replace the
copper pigtail. The old pigtail may contain corrosion which can
restrict flow. In addition, corrosion may flake off and wedge
between the regulator orifice and seat disc — preventing proper
lock -up.

The Problem
Many modem LP -Gas appliances are equipped with pilotless ignition
systems. Water heaters and older appliances use pilot lights, but It
has become a common practice for energy conscious homeowners to
shut-off the pilot when leaving home for extended periods of time. In
each instance, there Is no gas demand at all for extended periods.
The Consequences
If the first stage regulator falls to lock -up tight, usually as a result
of a wom seat disc or foreign material lodged between nozzle and
seat disc, pressure will build-up In the first stage piping — possibly
to a level that approaches tank pressure. Combining this With warm
ambient temperatures and cool ground, propane liquid may form In
the first stage piping.
When gas demand resumes, this liquid may pass through the second
stage regulator into the appliances and furnace. NOTE — the second
