GENERAL GUIDELINES AND RECOMMENDATIONS

Due to wide variations in installation and operating conditions the following information should be used only as a guideline to the

general principles of thermoplastic systems. Professional engineering design and installation of thermoplastic systems are

recommended. Questions concerning the application or installation of thermoplastic piping systems should be directed to the

manufacturer, design engineer, or the Plastic Piping Institute. Properly designed and installed thermoplastic pipe systems will give

years of quality service. It is important to consider the properties and limitations of the thermoplastic material selected for each

application for a trouble free durable system. The following points should be among those considered when designing or installing

thermoplastic systems:

1. MATERIAL SELECTION - Material selection should be based upon chemical resistance, operating pressures both positive and

negative, velocity, water hammer and surge occurrence, operating temperature, impact resistance, installation the operating

environment and other material selection considerations. Raw material manufacturers should be consulted for their recommendations

regarding your particular application.

2. TEMPERATURE - Temperature is an important consideration when designing thermoplastic piping systems. Excessive expansion

and contraction can cause breaks and joint failure if not considered during the design stage. Pressure ratings for thermoplastic pipe

decrease as temperatures increase; temperature de-rating factors must be used. Cooler temperatures decrease the impact

resistance of piping materials. Allowing fluids inside pipes to freeze may also cause breakage. During installation it is important to

shield pipe and fittings from heat radiation or infrared rays to minimize excessive temperature variations and expansion.

3. ABOVE GROUND INSTALLATIONS - Above ground installations should be properly supported with hangers and/or clamps.

Above ground pressure systems and large diameter drain lines should be thrust blocked at directional changes, line size changes,

valves and dead ends. Consideration should also be given to exposure of system to ultraviolet and infrared rays and the impact of

such exposure.

4. BELOW GROUND INSTALLATIONS - Below ground trenching requirements vary widely for different thermoplastic materials and

installation techniques. Proper bedding, back filling and thrust blocking materials and techniques must be used. External load, burial

depths, ground water levels and soil conditions should be considered when selecting piping material.

5. BUTT FUSION WELDING - When installing systems using butt fusion equipment, adverse environmental conditions must be

avoided. Equipment and piping materials must be protected from temperature extremes, excessive moisture and humidity, air

currents, and weld contaminants. Cooling times of fusion joints vary with wall thickness. Care should be taken not to disturb or test

joints prior to complete cooling. Contractors should carefully follow operating instructions for their fusion welding equipment and

manufacturers' installation and fusion guidelines.

6. SOLVENT CEMENT WELDING - When using solvent cements, manufacturers' guidelines and instructions must be carefully

followed. Cure times vary widely and are affected by pipe diameter, cement composition and weather. Joints should not be disturbed

prior to setting of cement. Joints should not be tested prior to complete curing of cement, Improper solvent cementing will cause

failure. Consult manufacturer for selection of solvent cement suitable for installation, environment and design. Failure to allow

complete cure before testing or pressurization may result in system failure.

7. TESTING - Permanent thrust blocks must be installed at all line size changes, changes and capped ends prior to pressure testing

of above and below ground installations. Test caps should be thrust blocked and carefully braced to accommodate extreme thrust

roads which can develop under test pressures. At no time should system test pressure exceed maximum pressure rating

recommended by manufacturer of fabricated fittings or weakest component in system.

8. CAUTION - In general compressed air is not recommended in plastic piping systems. Entrapped air under pressure can cause

shattering of the pipe and potential physical harm to equipment and personnel. It is extremely important to avoid trapped air through

the use of properly installed relief valves at high points. When filling systems, velocity should be selected according to piping material

used, generally 1FPS or less is recommended to avoid the introduction of air into the system. Under no circumstances should

systems be tested with compressed air.

9. HANDLING - Proper handling and storage of thermoplastic materials will help prevent installation problems. Exposure to

temperature extremes can cause breakage and distortion. Prior to and during installation pipe and fittings should be protected from

the environment, inspected, and handled carefully.

Working Temperature De-Rating

If operating or ambient temperatures are expected to exceed

73°F the working pressure of PVC must be de-rated. When

exposed to elevated temperatures thermoplastic pipe stiffness

and tensile strength decrease. This decrease results in a drop

in pressure capacity. Use the chart at left to determine the

pipe's maximum pressure rating at elevated temperatures by

multiplying the pipe pressure rating at 73°F by the de-rating

factor. The result will equal the maximum pressure at elevated

working temperature. maximum temperature variation

exceeds 306°F the installation of expansion loops, offsets or

bends is recommended. Maximum temperature variation (is

calculated by comparing lowest and highest ambient or

operating temperatures to the installation temperature. For

example, a system installed at (DT) is calculated by

comparing lowest and highest ambient or operating

temperatures to the installation temperature. For example, a

system installed at 50° F having an expected operational

There are additional sizes and diameters of PVC pipe available. Pipe sizes not shown on the above chart include SDR 26

NSF rated to 160 PSI and SDR 21 Rated to 200 PSI . All pipe pressure ratings are for water at 73°F. For other fluids and

service temperatures ratings will differ. Appropriate adjustments must be made. Pressure ratings are for straight lengths of

pipe only. Fabricated fittings are degraded by configuration and method of fabrication.

The above PVC pressure pipe is extruded from compounds which meet the specifications of ASTM D 1784 for Type 1

Grade 1 PVC. Schedule 40 and 80 PVC pipe meet the specifications of ASTM 1785. Pressure rated SDR PVC pipe meets

ASTM D 2241, and Is NSF approved.

Proper design and installation are essential elements for successful systems. Pipe manufacturer should be consulted

when selecting piping materials.

Solvent Cement Guidelines Solvent cementing is the preferred method for joining PVC and CPVC materials in the field. The solvent

cement dissolves the surfaces of pipe and fittings to form a continuous bond between the mating surfaces and

produces an actual chemical bond between the items to be joined. It has been shown that the single most

significant cause of system failure is improper joints. Properly installed cement joints produce strong pressure-

tight joints, enhancing the integrity of a well designed piping system.

There are many types of cements and primers on the market. The various cements are designed to be used in

a variety of conditions or with certain pipe sizes or materials. It is extremely important that as much care and

consideration is given to the selection of the proper solvent cement as is to the selection of the pipe, valves,

fittings and other components of the system.

The following information, based on ASTM D 2855, is meant to be used as a general overview of the cement

process. It is critical to the success of each installation that the installing contractor be experienced and

knowledgeable in the installation of solvent cement joints. The cement manufacturers' guidelines and

recommendations should also be followed. These instructions are based on normal installation and cannot

cover every combination of conditions. Cement manufacturer should be consulted for specific

recommendations for extreme or unusual conditions.

1. SQUARE CUT PIPE - The pipe should be square cut with the axis, using a fine toothed blade. Care

should be taken to remove all burrs and/or ridges left on the end of the pipe. The cut end of the pipe should be

chamfered and deburred to prevent removal of cement and softened material which will result in a leaking

fitting.

6. TESTING - NEVER TEST SYSTEMS WITH COMPRESSED AIR OR GASSES. Extreme care should be

taken to assure complete venting of entrapped air when filling the system with water or other liquids used for

testing. Prior to testing, systems must be fully blocked, vented and air must be bled from the system. Improper

testing or installation, especially poor cementing technique and/or entrapped air, may result in catastrophic

failure. For large systems, it is recommended that smaller segments be tested as installed to permit evaluation

and correction of improper installation techniques or materials.

2. TEST DRY FIT - Specified Fittings, Inc., provides sockets which are internally tapered. This allows for an

interference fit. For most pipe the interference will occur about 1 /3 to 2/3 into the socket. Sometimes pipe

which is at the tolerance extreme may be fully inserted into the socket until it bottoms. If this occurs care should

be used to apply sufficient cement to fill the gap between the pipe and fitting in order to ensure a strong leak-

free joint.

3. PRIMER APPLICATION - Primer should be applied to clean surfaces with a natural bristle brush.

Brush width socket. The primer is used to soften the pipe surface and must be applied liberally to ensure

proper penetration and softening. Work quickly and move to the cementing step while surfaces are still wet

with primer.

4. CEMENT APPLICATION - Working quickly, uniformly apply cement to primed socket and male end of

pipe while surfaces are still wet with primer. Immediately after applying the coat of cement and while both the

interior of the socket and the outside of the male pipe are still soft with solvent cement, forcefully bottom the

male end in the socket. Turn the pipe or fitting 1/4 to evenly distribute the cement. Assembly should be

completed immediately after the last application of cement. The pipe should be inserted with a steady, even

motion. Hammer blows should not be used. In large diameter pipe two or more workers may be needed.

Mechanical forcing equipment such as come-alongs or levers and braces may also be necessary. Until the

cement is set in the joint the pipe may back out of the fitting socket if not held in place. The joint must be in

place and not disturbed until the cement is set. Care should be taken not to disturb or apply force to joints

previously made. Fresh joints can be destroyed by early rough-handling.

5. CURE - Cure time can vary from minutes to days and is dependent upon installation temperature, specific

cement used, the size of the pipe and the dry joint tightness. Consult cement manufacturer for proper cure

times for your application.

DOUBLE CONTAINMENT

END TREATMENT

"A" "B" "C"

Thermoplastic pipe will expand and contract with temperature changes and with exposure to infrared

rays. When working with double contained pipe and fittings, the containment pipe is more vulnerable to

exposure to temperature changes and infrared rays thus more likely to expand or contract at greater

rates than the carrier pipe. When field joints are made on double containment systems that have not

been protected from exposure to conditions that would cause expansion and contraction, stress is

created which may cause joint failure when carrier and containment conditions equalize. To avoid this

type of faulty joint it is extremely important that double containment pipe and fittings be protected from

exposure to infrared rays and temperature variations. Storing pipe and fittings in a trailer or warehouse

until the time of installation is the best way to protect them from the above conditions. If inside storage is

impossible it is important that pipe and fittings are protected from sunlight by tarping them and keeping

them off the ground when air and ground temperatures are not equal.

All Double Safem pipe is shipped plain end with carrier and containment ends aligned flush ( as shown in

“A” below). All internal pipe supports are factory installed. All PVC fittings are furnished with socket ends,

carrier and containment socket stops are aligned to allow for simultaneous solvent cement field joints (

as shown in “B” below). All polyethylene and polypropylene fittings are furnished with ends aligned for

simultaneous butt fusion field joints (as shown in “C” below) Other end treatments are available and may

be special ordered.

JOINING METHODS: In PVC systems, the carrier and containment joints may be made

simultaneously. The simultaneous solvent cement process requires workers who are highly skilled and

experienced in the joining of PVC piping systems. In polyethylene and polypropylene systems

simultaneous fusion of carrier and containment pipe is recommended for maximum system integrity.

Double containment applications require strict adherence to the design principles for thermoplastic piping

systems. The services of an experienced and qualified thermoplastic piping engineer is highly

recommended. It is also important that the installing contractor be experienced in the installation of

thermoplastic piping systems. With these considerations in mind the appropriate piping materials and

field joining equipment should be carefully selected. With PVC systems the correct choice of primers and

cements to best meet the needs and conditions of each particular installation is critical to the success of

the system. Generally the use of heavy duty slow set cement is recommended for use with all sizes PVC

Double Safe™ pipe and fittings. For polyethylene and polypropylene systems, fusion equipment must be

in good condition and operated by experienced personnel. If the installing contractor is unsure as to the

best selections for the application, the manufacturer should be consulted for recommendations.

Additional trench width may be required to enable workers to properly install double containment piping

systems. Large diameter Double Safe™ pipe and fittings may require mechanical devices and additional

workers to properly position elbows and pipe. Additional workers may also be needed to operate fusion

equipment and make solvent cement joints.

PERSONNEL REQUIREMENTS TESTING

LEAK DETECTION

TESTING

Compressed air or gases should NEVER used to test PVC systems.

6. Working quickly while all surfaces are still wet with solvent cement, insert the pipe into socket with a turn

twisting motion. The pipe must be inserted into the socket with sufficient force to insure that the pipe is inserted

the full depth of the socket. Pressure should be kept on the pipe to prevent it from backing out until both surfaces

are firmly gripped. The time will vary with diameter and installation conditions.

When installing a double wall system, two or more men may be required to apply the primer and solvent cement

and insert pipe into sockets. As pipe size in systems increase, it becomes progressively more difficult to

accomplish two solvent cement joints simultaneously, i.e., the carrier joint and containment joint. It is extremely

critical that slow set cement be used for all sizes to ensure sufficient time to make proper solvent weld joints. On

large diameter systems as many as six men may be required. For the application of primer and cement, one man

per carrier and containment male end, one man per carrier and containment socket end, and two men to insert

and hold pipe in socket while cement seats.

For large systems with many joints it is recommended that sections of the system be isolated and tested

separately.

Testing shorter sections will ensure that faulty joints can be rapidly located and repaired. Final testing of the

completed system should be performed as above when installation is complete.

When leak detection cable is used, the pull strings must be tied together as fittings are joined. Tension should be

kept on pull string so that it does not lie on bottom of pipe and bond with joint. Pull string is to be used as a guide

for heavier gauge cord, or tape used to pull leak detection cable. Leak detection cable should be pulled as pipe

and fittings are installed. Leak detection cable is not as flexible as tape or cord and care should be used when

pulling through elbows and making directional changes.

Sufficient time must be allowed for cement joints to cure. Consult tables provided by solvent cement

manufacturers for set times.

Fill carrier pipe with water. Velocity should be 1 fps or less to avoid the introduction of excessive air in system.

Pre-test system with 10 feet of head pressure. If system does not hold 10 feet of head, drain system and repair

leaks. An alternate pre-test may be made using a vacuum test method. After successful completion of pre-test,

the system may be hydrostatically pressure tested. Slowly bring system to test pressure; any build up of pressure

on a filled system suggests entrapped air in system. Release pressure and vent system again.

Containment pipe may be tested after carrier pipe has passed hydrostatic pressure test. While carrier pipe is

under pressure, a vacuum test should be made on the containment pipe.

5. Flow on a heavy coating of solvent cement while the pipe and socket surfaces are still soft and damp from

application of primer. Apply solvent cement liberally to all surfaces and fill any gaps resulting from uneven

Double Safe™ PVC & CPVC Installation Guidelines

The installation of Specified Fittings, Inc. PVC & CPVC Double Safe™ pipe and fittings should be done

exercising all the care and precautions used when installing single line systems. Due to the variety of end

treatments and fitting styles available, and differing installation requirements set forth by specifying engineers,

certain aspects of your installation may not be addressed in this overview, The following information should be

2. Use appropriately sized applicators for primer and cement. Brushes used for application of cement and primer

should be approximately ½ the size of the pipe diameter.

4. It is critical that the primer is applied in sufficient quantity to soften and penetrate the pipe. More than one

application may be required to soften the pipe. Apply primer to outer surface of pipe and inner surface of socket

until these surfaces have been penetrated and softened.

Double Safe™ PE and PP pipe is available in a wide variety of pipe diameters and wall size combinations. Pipe is furnished in

20' lengths with flush ends for simultaneous fusion joints or with 6" carrier extensions for staggered field joints. Some pipe

material may be subject to minimum order quantities. Consult factory for availability.

Due to the wide variety of polyethylene pipe sizes available, it is not practical to show all possible size combinations. To

calculate annular space for your carrier and containment pipe sections: Subtract the OD of the carrier pipe from the ID of the

containment pipe. Divide the result by 2. The sum is equal to the maximum annular space available for your size selection.

Molded components generally have outside diameters which are greater than the OD of pip and would decrease the annular

space. Weld beads at fusion joints will also decrease the annular space. In general, when internal leak detection is not required

minimum annular space should be 1/2 to 1 inch. In systems where leak detection cable is to be installed within the annular

space, minimum annular space should be 1 to 2 inches. Consult your leak detection vendor for specific annular space

requirements.

Double containment applications require strict adherence to the general guidelines for butt fusion. Certain applications may

require additional steps; all procedures should be closely followed to assure a successful installation. The following may be used

as a general guideline when installing butt fused double containment piping systems. Please consult factory prior to installation to

verify that the proper fusion welding procedures are followed for your installation.

4. PLANE ENDS - Verify that ends of and containment pipe

are flush prior to planing. If ends are not flush it is an

indication of expansion of containment pipe due to excess

exposure to sunlight or infrared rays. Containment pipe

must be covered and allowed to contract to flush position

prior to planing ends or making weld. If pipe ends are flush,

planer should be used to lightly shave ends and remove

contaminants. Planed ends should be rechecked for proper

alignment.

5. MELT ENDS - Position heater between pipe ends. Bring

ends to heater at the recommended melt pressure. Allow

melt to proceed until uniform symmetrical melt beads are

formed. Drop pressure to allow heat to penetrate pipe

material and prevent dry welds.

DOUBLE CONTAINMENT BUTT FUSION GUIDELINES

6. MAKE WELD - Once melt is complete, work quickly to

separate ends to allow for removal of heater. Bring ends

together and increase pressure to recommended weld

pressure. Allow joint to cool before releasing pressure and

removing material from fusion clamps.

8. Test weld as above and check for free movement of pull

string. Continue installation carefully following fusion guidelines.

1. PIPE STORAGE - Special care should be taken to

shield double walled pipe and from exposure to direct

sunlight and infrared rays. This may be accomplished by

shielding with tarps or other materials. Failure to shield pipe

and fittings may cause expansion of the containment pipe

and result in stressed or faulty welds on carrier lines.

2. EQUIPMENT - Fusion equipment should be clean and in

good repair. Clamps will be needed for each size

containment pipe and for any single line weld to be made.

3. PREPARE PIPE - New preassembled pipe and fittings

are shipped with ends aligned and square cut. When pipe

and fittings are fixtured in clamps, ends should be

inspected to make sure that carrier and containment pipe

ends are free from dirt and foreign material. When fittings

and pipe are placed in clamps, pipe support must be

positioned under clamp surface. This step ensures proper

alignment of pipe during the fusion procedure.

7. TEST WELD - To ensure that carrier pipe has been

properly aligned and fused, it is recommended that a low

pressure (5 PSI) test be made on carrier line prior to

proceeding to next weld.

SPECIAL INSTRUCTIONS FOR SIMULTANEOUS WELDING

WITH LEAK DETECTION CABLE.

Upon request Specified Fittings, Inc. will install pull string for leak

detection cable installation. When systems are installed using a

simultaneous weld, the following steps should be added to the

double containment butt fusion guidelines.

1. A minimum of four workers is required for each welding

machine to be used. These workers will be responsible for

operation of welding machine, joining of pull string, and

tensioning pull string during weld. Certain Butt Fusion equipment

may require additional machine operators.

2. When pipe is fixtured in clamps, pull string should be at the

six o'clock position. Pull string should be positioned in such a

way that it will not be snagged by the planer, nor make contact

with heater or molten material during the melt step.

3. When melt is complete, remove heater and separate ends.

Working quickly, securely joins the ends of pull string.

4. Tension should be applied to both ends of pull string to raise

string off containment pipe and away from weld beads.

5. Bring ends to be fused together quickly and adjust machine to

weld pressure.

6. Tension should be kept on pull string until weld is complete

and weld beads are cooled.

7. Pull string may be gently pulled back and forth during weld to

prevent joining of pull string to containment pipe weld surface.

Contractor shall follow manufacturer's guidelines for system testing. A test pressure of 50 PSI above the normal operating

pressure is recommended, in no case should pressure exceed rating of lowest rated component in system. Hydrostatically

tested systems shall be completely bled of entrapped air through the use of relief valves at all high points. Thrust blocks

shall be installed at all capped ends and directional changes. All containment pipe must be center loaded. Fill velocity shall

not exceed 1 fps. Air pressure testing of carrier pipe is expressly prohibited due to the catastrophic nature of failure should

failure occur.

All dual containment pipe and fittings shall be factory assembled. Fabricated carrier fittings must be manufactured using

butt fusion. All pipe and fittings to be manufactured with internal pipe supports to center the carrier pipe within the annular

space of the containment pipe. No split, reworked, fillet or extrusion welded carrier fittings shall be used.

System design shall be in accordance with standard industry practice for thermoplastic industrial piping systems. System

design must take into consideration such factors as: operating and test pressures; operating and installation temperatures;

fluid, chemical and temperature de-rating factors; support spacing; anchoring; external and internal thrust blocks;

occurrence of water hammer and surge pressures; chemical and exposure to infrared and ultraviolet rays. For below

ground installations design consideration must also be given to external load, internal load, burial depth, ground water

levels and soil conditions.

This specification covers the manufacturer's requirements for Polyethylene Double Safe™ dual containment pipe and

fittings.

All carrier and containment piping material shall be High Density Polyethylene as per ASTM D-3350. All pipe must meet the

dimensional requirements of ASTM F-714 specifications for plastic pipe based on controlled outside diameter or, ASTM D-

2447 for plastic pipe, schedule 40 and 80, based on outside diameter. All double containment pipe and fittings shall be of

American make as manufactured by Specified Fittings, Inc., Bellingham, Washington.

Field joints shall be made using simultaneous butt fusion. All contractor personnel involved in the making of fused joints

must be experienced in, and follow, the correct procedure for butt fusion as described in ASTM D-2657. All factory
