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. VJhere 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 overtime.
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 e)Nbfts 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
variationssuch as rocks, salts, fertilizer, moisture concentration, oxygen
concentration, etc.
Preventing Corrosion
Protecting underground
tanks from corrosion is
casflyachievedbytheuse
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
----... _- erdemal protective
coating insulates the steel from the snit environment, thus preventing
theflow of corrosion currentfrom the anode to the cathode. Aneffective
extemalcoatingcmptotectover99%offfietank surfamarea. However;
no coating is perfect Damage from construction prsolstresses create
tiny defects, which may result in accelerated corrosion afthe defect
Cathodic protection prevents corrosion at those defects by applying
DC current from an external source, forcing the tank to become
cathode. Application ofsufficient DCcurrenttothetankwillpreventany
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 mare commonly used for large structures such as large diameter
pipelines. Electrical isolation of the tank from metallic piping systems
and electrical' grounds is crid6d for the cathodic protection system's
effectiveness.
Haar sacrificial Cathodic Protection Wotks
Sacdtiufal 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 to 1.25Vvolts 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
Them are a variety of anode sizes and alloys used for cathodic
protection. The two primary alloys are designed as H-1 (orAZ63) 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 pmtection of underground propane tanks. The High
Potential alloy is 99% pure magnesium having an open circuit potential
up to -f.M This alloy should be used for soil applications over 10,000
ohm -cm resistivity.
Thg two most common anode sizes used for underground propane
tanks are 9lb. and 171b. The siza designation relates to the mad weight,
to' of P2 TW insulated wire is attached to the anodes. Anodes are
then backnlled in a mixture of gypsum, bentonfte, and sodium sulfate
to lower the electrical resistance of the anode to soil. The mudure 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 45lb.
Application 6ecommendatinns
Magnesium anodes can protect underground tanks in most soil
conditions. The H-1 alloy is generally very effective. The following chart
provides size and quantityrecommendalions forvarfous size tanks based
on conservative design assumptions. This chart covers soil conditions
up to 10,000 ohm-ceml'meter resisft. Resistivides higher than
10,000 ohm -centimeter generally represent very dry soils. Verification
of soil resistivity can be performed through soil analysis. Contact, us
fr design recommendations in locations where soil resistivftias exceed
10,000 ohm -cm, or if there is m 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 he exthmally coated Ifift
a corrosion resistant material. The service line should be electrically
isolated at the house with an insulating idling or union. if service pipe
is less than 50' fn length, the tank anodes will provide sufnclont current
to protect both tank and pipe. For longer iengthsofpipe, anaddmonal
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. Copperandsteel create agalvanic couplethatwillaccelerate
corrosion of the steel tank when directly connected to copper piping.
Generally, copper piping does not require cathodic protection.
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 voltmaterinsertthe red test lead into the Volt
lack 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 muffivalve. A good solid connection is very important.
(DO NOTconoectto shroud).
STEP 2: Insertthe black tastlead into the Common lack on the meter,
and connect the opposite and of the lead to a charged reference
electrode (14 cell).
STEP 3: Remove protective cap from the porous plug at bottom and
of electrode. Place porous plug and 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 difHculfy is encountered
obtaining readings, moisten soil with water or dig Ye 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-0.851)v or more
negative. fNote: If any ofthefour readings are below (lessnegative)
-0.850v than 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 wi71 turn blue in
color and there should always be excess crystals atthe 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 and is facing in the down position
and let stand for i hour before use. This will allow the porous plug
to become completely saturated before use.

4.Anodes are shipped in either cardboard boxes or mulfi-wall
papersacks. Remove outercontainerandburythecloth bagged
anode. If anode is supplied in plastic bag, remove plastic bag
before installing.
5.Install anodes approximately two to three feetfrom 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.ARer placing the anode, stretch cut the anode connection wire
and extend overto a connection point on the flank fill pipe.
7. Cover the anode with approximately six inches of backffll and
pour 5 gallons of water on the anode to saturate the prepared
backi6. Water is necessary to acfirate the anode.
B.Conneet the anode ultra to the tank with a low electrical
resistance connection. Examples are threaded stud on the
tank fill pipe or any accessible metallic connect on 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 Mte,
subsequent testing of the tank can include measurement of
anode output and verification otperformance.
1o.Verh`y performance of the anode using an appropriate test

Freeze-up inside the regulator.
Ice
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 pigtails that are kinked or
bent Where free flow of the tp-Gas is restricted. These freeze -ups
can occur when the moisture, gas flow and temperature combine to
crew a hazardous condition. Freeze -ups can occur at temperatures
above V 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 he tahlmed to the supplier. Any
container suspected of staving excessive moisture should be treated
wfdr 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 SnffP' leaflet
2 Are instructed to never tamper with the system.
3. Know that when protective hoods are used to enclose
regulators andfor valves, that these hoods most 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.
Underground Installations
Special 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 tightly in place and the vent is not
protected with a proper vent tube, opening above any potential water
level_
Most problems occur because the waterproof dome on the buried
storage tank does not extend above the ground level sufncfengy to
keep out water and mud. — - - - --

General Warning
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
and rubber, As a general recommendation,Regulatorsshould
be replaced in accordance With all of the recommendations
outlined in this safety warning. The recommended service
life of a regulator is one of many factors that must be
considered in determining when to replace a regulator.
The environment and conditions Or use WDI OUL011laee u1c c,vc
service life of these products. Periodic inspection and maintenance
are essential.
Bemuse Rego Produc`s have a long and proven record of quality
and service, LP -Gas dealers may target the hazards that can occur
because a regulator Is bsed beyond its safe service rife. 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 a developing trend in state legislation and
in proposed national ieglsiation to make the owners of products
responsible for replacing products before they reach the and of their
safe useful life. tp-Gas dealers should be aware of legislation which
could affect them.

��Qfions, the use of a two -stage system offers the ultimate in pin-
_ I regulation. Two -stage regulation can result in a mom profitable
_R-Eas operation for the dealer resulting from less maintenance and
V..ar installation callbacks — and there is no better time than now for
'-stalling RegO Regulators in two -stage systems.
ifrifform Appliance Pressure
-Ee installation of a two -stage system — one high pressure regulator
a3 the container to compensate for varied inlet pressures, and one
s r pressure regulator at the building to supply a constant delivery
pr_ssure to the appliances — helps ensure maximum efficiency
asd trouble -free operation year-round. It Is important to note that
t:>t-aa pressure at the appliances can vary up to 4° w.c, using single -
stage systems, two -stage systems keep pressure variations within
e ve.c. New high -efficiency appliances require this closer pressure
ooriml lbr proper Ignition and stable, efficient operation- in fact one
,:a-jor manufacturer requires the use of WO -stage systems with their
appliances.
Reduced Freeze-ups/Service Calls
,Regulator freeze-up occurs when moisture in the gas condenses and
,,eezes on cold surfaces of the regulator nozzle. The nozzle becomes
chilledwhen high pressure gas expands acrgss It Into the regulator
body. This chllmg action is mom severe In single -stage systems 2s
gas expands from tank pressure to 114 w.c. through a single regulator
nozzle.
Size The System Correctly
Prior to installing your bvo-stage system, be sure the system pipe
and tubing Is property sized. Proper sizing will help ensure constant
delivery pressure to the appliances during 9uctuating loads at Bit
times. Just as important, be sure the Rego Regulator's you choose
are capable of handling the desired load. This is another advantage
of two -stage systems — they are capable of handling much
mote BTU'S hr. than single -stage systems. The RegO `LP -Gas

and proper regulator selection.
r T❑ Ap piiancesiFu macs
Two -stage systems can greatly reduce the possibility of freeze -ups
and resulting service calls as the expansion of gas from tank pressure
to 11° ve.c. is chided into two steps, with less shifting 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 possiblfty of semnd-stage freeze-up.
Service calls for pilot outages and electronic ignition system faluras
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 o
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 toads. This is the least expensive
and best method of correcting the problem.
Allowance for Future Appliances
A high degree of flexibility is offered in new installations of two -
stage systems. Appliances can be added later to the present load —
provided the high pressure regulator can handle the increase— by the
addition of second low pressure regulator. Sfnca appliances can be
regulated independently, demands from other parts of the installation
will not affect their Individual performances.
Replace Pigtails
if you ere replacing an old regulator, remember to replace the
copper pigtel. The old pigtaff may contain corrosion which ran
restrict flow. In addition, corrosion may flake off and wedge
between the regulator orfica and seat disc — preventing proper
lock -up.

The Problem
Many modem LP-Ges 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 homeovmers to
shut-off the pilot when leaving home for extended periods of rime. In
each instance, there is no gas demand at all for extended periods.
The Consequences
if the first Stage regulator fails to lock -up light usually as a result
Of a worn seat disc or foreign material lodged between nozzle and
sea-, Else, pressure w01 build-up in the that stage Piping — possibly
to a level that approaches tank Pressure. Combining this efirh wam
