The rate of loading shall be uniform and such that the compression is completed within 2 to 5 minutes. On removal of the load, examine the specimens for evidence of splitting, cracking, or breaking.

3.8 Frequency of Tests. Long-term hydrostatic hoop strength test shall be verified annually by the rnanufac- turer or on any change in formulation or extrusion technique as specified in Table 3.1. Impact tests shall exceed the minimum values listed in Table 3.2 and be tested a t 2-hour intervals for each extrusion line as specified in Par. 3.4. Extrusion quality (acetone test) shall be performed a t 2-hour intervals for each extrusion line as specified in Par. 3.6. Short-term hydrostatic hoop strength tests shall be performed a t 2-hour intervals for each extrusion line as specified in Table 3.1. Dimensions and tolerances of each piece of pipe shall be checked with rejection of any piece exceeding toler-

- > r 3 % B

ances listed in Table 5.1. Flattening tests as specified in Par. 3.7 shall be run at 8-hour intervals. Quality control records shall contain data of all tests and be open to inspection by the purchaser.

3.9 Hydrostatic Mill Tests. Hydrostatic testing of pipe manufactured to this specification shall be done at a hoop stress level of 3,000 psi (20MPa) with water between temperatures of 65-90°F (18-32°C). Frequency of hydrostatic tests shall be as agreed upon between manufacturer and purchaser.

3.10 Retest and Rejection. When the pipe fails to meet the specification requirement in any test, additional tests shall be made on the pipe produced back to the previous acceptable result to select the pipe produced in the interim that does pass the requirement. Pipe that does not meet the requirement shall be rejected.

4.1 Hydrostat ic Design. The hydrostatic design basis is based on the hydrostatic strength as determined in accordance with ASTM D 2837: Method for Obtairting Hydrostatic Design Basis for Thermoplastic Pipe Muterials. Design stresses are based on a design service factor applied to the hydrostatic design basis. Materials meeting this specification have a hydrostatic design basis of 4,000 psi (27MPa) for water service and natural gas (methane) at 73°F (23°C). After applying a 0.5 design service factor, the design stress rating at

73°F (23°C) will be 2000 psi (14MPa). More detailed information on service factors to convert the hydrostatic design basis to hydrostatic design stresses is given in Appendix A. Information regarding commercial compounds meeting the design stress requirements of this specification is provided in the Technical Report TR-4, published by and available from the Plastic Pipe Insti- tute, a division of The Society of the Plastics Industry, Inc., 355 Lexington Avenue, New York, New York 10017.

APPENDIX A RECOMMENDED PRACTICE

FOR CARE AND USE O F THERMOPLASTIC LINE P I P E PVC and CPVC

SECTION A l

DESIGN FOR INTERNAL PRESSURE A 1.1 General. The concept of engineering design

for plastics, including PVC and CPVC pipe is different from that used in designing with metals. A large fraction of the yield strength of a metal is widely used for design purposes a t ambient or near ambient temperatures. Plastics unlike structural metals a t ambient temperatures, are influenced by the time duration of stress as well as relatively small changes in temperatures. Some environments or chemicals also lower the properties of the plastics. All of these factors must be considered in determining safe operating stress levels for long-term service.

A 1.2 Pressure Formula. The design pressure or the minimum wall thickness for a given size of PVC and CPVC pipe is determined using one of the following formulas:

where D = outside diameter, inches P =design pressure, psi S = long term hydrostatic strength, psi t = minimum wall thickness, inches FI = service factor F, = safety factor K = Standard Dimension Ratio

A 1.3 Hydrostat ic S t r e n g t h (S). The long-term hydrostatic strength of the PVC and CPVC materials covered by API Spec 5LP is 4000 psi (27 MPa) for water service and natural gas (methane) a t 73°F (23°C) or cooler.

A 1.4 Service Factor (F,). Environmental service factors are used in the development of design pressure rating (P) when the PVC and CPVC materials will be subjected to high service temperatures and/or to particular chemical environments that reduce their long-term strength. Temperature service factors are given in Table Al . The effect of a particular chemical environment and the appropriate service factor, if any, should be determined or requested from the PVC and CPVC pipe supplier. Hydrocarbons, for instance, significantly affect the long-term strength of PVC and CPVC pipe. A service factor of 0.4 has been found satisfactory for transport of most crude oils and is suggested if more precise data are not available.

A 1.5 Safe ty F a c t o r (FP). The design pressure rating of PVC and CPVC pipe for water or neutral environment service is developed by use of a safety factor of 0.5. A like factor of safety is generally used for PVC and CPVC pipe used for crude oil service. PVC and CPVC pipe used for natural gas service and subject

to U. S. Government regulations (Minimum Federal Safety Standards) has safety (design) factors varying from 0.32 to 0.20 depending on a specific classification for the location where the proposed installation is to be made. This safety factor for plastic gas piping installa- tions does provide for use of the pipe at service temperatures above 73°F (23°C) but not exceeding 100°F (38°C).

A 1.6 Design Stress - Pressure Rating (Examples). The design stress for PVC and CPVC pipe used to con- vey crude oil a t 73°F (23°C) would be the long-term hydrostatic strength (4000 psi) (27 MPa) x the chemical service factor (0.4) x the safety factor (0.5) or 800 psi (5 MPa). At a temperature of 120°F (48°C) for the flowing crude oil, a temperature service factor of 0.4 from Table A l would have to be used to reduce the design stress to 320 psi (2 MPa). A PVC pipe having a 200 psi (1.4 MPa) pressure rating for water at 73°F (23°C) would have a crude oil pressure rating at 73°F (23°C) of 200 x 0.4 or 80 psi (0.55 MPa) and at 120°F (49°C) it would be 80 x 0.4 or 32 psi (0.22 MPa).

NOTE: Table A4 lists working pressures for PVC and

A 1.7 Water Hammer. Water hammer occurs when a liquid flowing in a pipe has the velocity altered suddenly. The liquid in motion possesses energy which must be dissipated. This dissipation of energy creates a series of pressure waves in the pipe which alternates in direction and may create dangerous pressures. Water hammer pressures can be determined with Chart 2.

SECTION A2 P I P E SIZING

A 2.1 Pipe Sizes. Dimensions, weights and tolerances of PVC and CPVC pipe and fittings are listed in Table 5.1.

A 2.2 Pressure Drop. Pressure drops of water in PVC and CPVC pipe can be determined with Chart 1.

A 2.3 Velocity of Fluid. A maximum fluid velocity of 5 feet per second is recommended by Plastics Pipe Institute. (PPI TR-14 Water Flow Characteristics of Thermoplastic Pipe)

A 2.4 Gas Transmission. The requirements for pipelines for the transport of gas within the USA are controlled by the Department of Transportation, Hazard- ous Materials Regulation Board, Office of Pipeline Safety, Part 192, Title 49 of the Code of Federal Regulations. “Transportation of Natural Gas and Other Gas by Pipelines: Minimum Federal Safety Standards.” Additional information on such pipelines is given in the ASME Guide for Gas Transmission and Distribution Piping Systems. These Federal Regulations do not apply to the gathering of gas outside of cities, towns, villages, subdivisions, business centers, shopping centers, and community developments.

SECTION A3 SYSTEM DESIGN

A 3.1 Thermal Coefficient of Expansion. Plastic pipe expands and contracts with changes in temperature considerably more than steel pipe. The average coefficient of thermal expansion for PVC and CPVC pipe is 3.7 x lo-” in/in/oF. Specific formulations may have different values. The change in lengths in Table A2 is calculated for the average value. These rates of expansion and contraction, however, are for unconfined pipe. When properly installed underground, PVC and CPVC pipe is restrained by the soil with little chance of failure from thermal expansion and contraction. Plastic pipe has a much lower modulus of elasticity than steel pipe resulting in far lower stresses due to equivalent expansion and contraction. In addition, once installed and in service, the temperature variation expected is generally quite normal and, therefore, not likely to induce any significant stress in the PVC and CPVC pipe. The critical period for thermal effects is during installation. Contraction or “pull-out” of solvent- cemented joints prior to complete cure of the joint may result in a failure. Once the joints have properly set, there is very little possibility of joint failure. Properly compacted soil acts to confine the entire pipe and distribute any stress over its full strength.

A 3.2 Trenching. Plastic pipe must be laid and continuously supported on undisturbed or well compacted soil. The trench should be wide enough to allow for some slack in the pipe and sufficient space for compacting the side fills. If ledge, rock, hardpan, or boulders are encountered, the trench bottom should be undercut by at least 4 inches and refilled with good bearing small particle size soil. The trench bottom should have a uniform grade before installing the PVC and CPVC pipe.

A 3.3 Anchoring and Thrust Blocks. Internal pressure causes a thrust acting on joints and fittings at elbows, tees and valves. This force increases with pipe size. Anchors and thrust blocks should be used on systems with pipe sizes larger than 2 inches. These anchors and thrust blocks are usually cast concrete with a contoured fitted bearing surface to distribute the stresses in the pipe or fitting.

A 3.4 Bends, Branches and Tees. Changes in direction with PVC and CPVC pipe may be made with bends, elbows and tees. Bends must be gentle with a long radius. They must be free of buckles, cracks, or other evidence of damage. Elbows must be used for more abrupt changes in direction. If valves are placed in the line, a small bellhole should be dug to accom- modate it so that the pipe itself can rest on firm soil. The valves should rest on concrete or other suitable support.

SECTION A4 SHIPPING, HANDLING AND STORAGE

A 4.1 Packaging. The manufacturer of plastic pipe should strap the pipe in bundles with sufficient tension

on the straps to prevent slipping of individual pipes. The pipes should not be distorted out of round by the straps. End closures may be required to prevent contamination of the internal pipe surfaces.

A 4.2 Handling and Storage. Plastic pipe should be stored so as to minimize the possibility of damaging by crushing or piercing. It should not be stored for extended periods i n direct sunlight. Users should not store PVC and CPVC pipe exposed to direct sunlight for more than a few weeks unless it has been shown that the material used to make the pipe has been formulated to be resistant to ultra-violet radiant energy (direct sunlight). I t is recommended to cover or shade pipe. The exact height PVC and CPVC pipe can be stacked depends on many factors such as size, wall thickness, and ambient temperatures. The pipe should not be loaded to the point where the pipe section is forced out of round. The pipe should be protected from fire, excessive heat, or harmful chemicals. The inside of the pipe should not be contaminated by rocks, dust, oils, or other foreign materials. Internal contaminates should be removed by washing before the pipe is installed.

A 4.3 Shipping. Pipe should be loaded or unloaded using two men if necessary to prevent damage. Poor handling techniques may result in gouges, scratches, cuts, or punctures. Do not allow the pipe to be thrown from a truck while stringing along a trench. The pipe should be supported to minimize movement or vibration between the pipe and its supports while being transported. Do not transport equipment on top of the pipe which may cause damage from sharp edges and other projections.

SECTION A5 ASSEMBLY

A 5.1 Field Inspection. Plastic pipe should be carefully inspected for cuts, gouges, deep scratches, damaged ends, and other major imperfections before use. Defective pipe should be rejected.

A 5.2 Cutting. Plastic pipe can be easily cut with an ordinary hacksaw or carpenter’s saw. Fine tooth blades with little or no set should be used for best results. The pipe should be cut square and all burrs removed with a sharp knife, finetooth file, or other suitable device. A miter box is useful to insure square cut ends. Standard steel pipe or tubing cutters a re not recommended for cutting plastic pipe since they might cause excessive heat and pressures that can result in cracked or irregular ends. There are special cutters available with extra wide rollers and thin cutting wheels which have been designed for cutting plastic pipe.

A 5.3 Solvent Cement Fittings. PVC and CPVC pipe and fittings are manufactured to close tolerances. The close tolerances are required to insure satisfactory “interference” fit between the pipe and fittings during the solvent adhesive joining. Use only pipe and fitting



combinations that give interference fits. Pipe loose in the socket may not properly bond chemically. The allowable tolerances should assure a forced fi t and, when solvent is applied, will readily mate, thus assuring bonding equal in strength to pipe or fittings.

A 5.4 Solvent Cement Joining Requirements. PVC and CPVC may be jointed to itself using the correct solvent cement. The solvent cement should meet the requirements of ASTM D2564: Specification for Solvent Cements f o r Poly (Vinyl Chloride) (PVC) Plastic Pipe und Fittings or ASTM F493: Solvent Cement f o r Chlorinated Poly (Vinyl Chloride) (CPVC) Plastic Pipe und Fittings.

The correct procedure for making a solvent cement joint is specified by ASTM D2855: Recommended Prac- tice for Making Solvent Cemented Joints With Poly (Vinyl Chloride) (PVC) Pipe and Fittings, or as follows:

a. Solvent Adhesive. PVC solvent cements a r e available in three general viscosity categories; light, medium and heavy. The light cements are intended for use with pipes and fittings up through two inch nominal size. Medium cements are intended for 2% in. through 6 in. sizes, and heavy grades are used for 8 in. through 12 in. sizes.

b. Use only PVC and CPVC primer and solvent

c. Clean off all dust, dirt, moisture, and oil from the bell and spigot surfaces to be cemented. Cleaners can be either chemical or mechanical.

d. Apply primer to the bell and spigot surfaces to be cemented.

e. Apply solvent cement to spigot or male end only. Apply a uniform even coating making sure that the coated area on the pipe is equal to the fitting belled end.

f. Insert the pipe quickly into the socket turning the pipe slightly during insertion to insure an even distribution of the solvent cement. Make sure the pipe is inserted to the ful l socket depth and does not extrude before setting.

g. Do not stress the joint while making successive

cement.

joints. See Table A3 for joint cure schedules.

A 5.5 Threaded Joints. PVC and CPVC pipe and fittings can be joined by threading. Only Schedule 80 pipe and fittings should be threaded. The specifications for threaded fittings are ASTM D2464: Specification for Threaded Poly (Vinyl Chloride) (PVC) Plastic Pzpe Fittirigs Schedde NO and ASTM F437: Spocificcitioti f o r Threaded CPVC Plastic Pipe Fittings. A suitable thread lubricant or sealant recommended by the pipe supplier should be used on the threads. The fittings should be made up approximately 5 turns past hand tight using strap wrenches. Do not over tighten.

A 5.6 Transition Fittings. Transition fittings are available for connecting PVC and CPVC pipe to pipes of other materials. The purpose of a transition fitting is to provide a permanent pressure-tight connection between two materiais that cannot be directly jointed.

A 5.7 Gasketed Joints. Gasketed joints a re available and should meet the requirements of ASTM D 3139 Joints For Plastic Pressure Pipe Using FleLible Elastomeric Seals. The installation should be in accordance with the manufacturer’s recommendation.

SECTION A6 P I P E PLACEMENT

A 6.1 Joint Cure. Plastic pipe may be joined in the ditch or above grade. Generally most joining is done above gracie prior to lowering the pipe into the ditch. Sufficient time must be allowed for solvent-cement joints to set up before handling. See Table A3 for typical cure times. The pipe should be handled with reasonable care as it is lowered into the ditch. It should not be subjected to unnecessary strains such as bending or twisting a t any time.

A 6.2 Leak Test. All PVC and CPVC lines should be tested for leaks before burial. The line may be in the trench and the center of each pipe joint anchored with backfill o r it may be tested above grade before installing in the trench. Leak testing may be done with air or water. Leak testing with air should be at pressure under 5 psi (34.5 KPa) due to potential personnel hazard. Leaks can be found with tracers or by “soap- ing” ail joints. Water is the preferred test media. Pres- sures up to the line design pressure can be used. Leaks can be found by observation or by determining pressure drop in a closed system, or by measuring the leak rate of a closed system. Special precautions must be taken when leak testing with water at extreme temperatures. In hot climates, the pipe exposed in trenches with little air circulation can become so hot that it has little strength. Occasionally, a downgrade drain valve is opened while the upgrade valve remains closed. The resulting vacuum can collapse a hot pipe. At temperatures below 32°F (O’C), the water test media should be drained before it freezes i n the pipe system.

A 6.3 Proof Test. Pressure proof testing is usually done a t 1.5 times the design pressure. Gas or air should not be used for proof testing due to the possibility of dangerous failures. The pipe should be anchored by at least some backfill over each piece of pipe. Pipe should withstand test pressure without pressure loss for a con- tinuous 16 hour period. Pressure should be applied a t a time of minimum temperature variation. Over night may be preferred due to test duration. Pipe temperature should not be more than 100°F (38°C) for the duration of the test.



A 6.4 Backfill. Material used to surround the pipe should be stable soil with a particle size of inch or less. Backfill material, to a height of a t least 4 inches over the pipe, should be laid and compacted in 6 inch layers to insure lateral restraint. Care must be exer- cised to not float the pipe from its position when flood- ing the trench to consolidate backfill. The possibility of deforming or collapsing the pipe during backfilling operations would be minimized by applying internal pressure to the pipe. The backfill should not be compacted with heavy equipment unless the plastic pipe has a t least 24 inches (0.6m) of cover and an internal pressure exceeding 15 psi (1.0 MPa). Additional information is contained in ASTM D 2774: Recommended Practice for Underground Installation of ThPrmoplastie Pressure Pi pirig.

Surge Pressure And Water Hammer

Whenever the velocity of a moving liquid in a pipeline changes, a pressure change results. Under some conditions, such a pressure change or surge pressure, can cause water hammer, and this condition can be suffi- ciently extreme to rupture pipe and fittings. Such a change in velocity can be created by a quick closing valve, a check valve, or a pump start-up, and if the velocity change is rapid enough the surge pressure may reach its maximum of ultimate value. This maximum surge pressure is a function of the velocity of the pressure wave, the change in the flow velocity plus two constants-mass and acceleration.

Maximum Surge Pressure

The maximum surge pressures for a PVC pipe line can be computed for the formula and components below:

p = a - w v 144g

w = weight of fluid (Ib/cu f t ) p = pressure rise (psi) a = surge wave velocity (fps) g = acceleration due to gravity (32.2 fps/sec) V = Velocity change (fps)

In this case the major unknown is the velocity of the pressure wave which can be computed from the formula.

W =weight of fluid (Ib/cu ft) k =bulk modulus of compressibility of liquid

E =Young’s modulus of elasticity for pipe

d =inside diameter of pipe (in) e =thickness of pipe wail (in)

(psi)

wall material (psi)

By taking values of 300.000 psi for “k” and 400,000 psi for E and by using various d/e combinations, we can compute value for “a”. Then we can utilize these values for “a” and develop the Surge Wave Constant curve shown in the graph. Using 450,000 psi for E with other values unchanged gives the second curve.

Calculations

To determine the Maximum Surge Pressure for a PVC pipeline -

1. Determine the pipe dimensions (SDR or die)

2. Determine the surge wave constant (C,) from the graph, Chart 2.

3. Determine the change in flow velocity (V) in fps.

4. Compute the maximum surge pressure

5. Adjust (p) for temperature if necessary.

P = C,(V)
