Caw LP www.performancepipe.com Technical Note 814 -TN Engineering Considerations for Temperature Change Like most materials, polyethylene is affected by temperature change. However, polyethylene's response to temperature change is significant and unique when compared to other "traditional" piping materials. Polyethylene pipe design for thermal change may be significantly different compared to other piping materials. Polyethylene pipe can be installed and operated in sub - freezing conditions. Ice in the pipe will restrict or stop flow, but not cause pipe breakage. Care must be taken during installation to avoid impact and suddenly applied high stress. In response to changing temperature, unrestrained polyethylene pipe will undergo a length change. Anchored or end restrained pipe will develop longitudinal stresses instead of undergoing a change in length. This stress will be tensile during temperature decrease, or compressive during temperature increase. If the compressive stress level exceeds the column buckling resistance of the restrained length, then lateral buckling (or snaking) will occur. While thermal stresses are well tolerated by polyethylene pipe, anchored or restrained pipe may apply stress to restraining structures. The resulting stress or thrust loads can be significant and the restraining structures must be designed to resist the anticipated loads. The PlexCalc II program is available from Performance Pipe to aid in performing many of the calculations in this technical note. PlexCalc II is located on the Performance Pipe CD -Rom. Unrestrained Thermal Effects The theoretical change in length for an unrestrained pipe placed on a frictionless surface can be determined from Equation 1. AL =LaAT (1) where: AL = length change, in L = pipe length, in a = thermal expansion coefficient, in /in / °F AT = temperature change, °F The coefficient of thermal expansion for DriscoPlex high density polyethylene pipe material is about 9.0 • x 10 -5 in /in / °F. This coefficient results in an approximate expansion for pipe of 1/10/100, that is, 1 in for each 10° F change for each 100 ft of pipe. This is a significant length change compared to other piping materials and should be taken into account in piping system design. A temperature rise results in a length increase while a temperature drop results in a length decrease. NOTICE.

COMPUx ? www.performancepipe.com End Restrained Thermal Effects A length of pipe that is restrained or anchored on both ends and placed on a frictionless surface will exhibit a substantially different reaction to temperature change than an unrestrained pipe. If the pipe is restrained in a straight line between two points and the temperature decreases, the pipe will attempt to decrease in length. Because of the end restraints, a length change is not possible, so a tensile stress is created in the longitudinal direction along the pipe. This stress can be determined using Equation 2. cr = Ea AT (2) where terms are as defined above, and a = longitudinal stress in pipe, psi E = elastic modulus, psi The selection of the modulus can have a large impact on the calculated stress. As with all thermoplastic materials, polyethylene's modulus and therefore its stiffness, is a function of temperature and the duration of the applied load. To select the appropriate elastic modulus, these two variables must be known. When determining the appropriate time interval, it is important to consider that heat transfer occurs at relatively slow rates through the wall of polyethylene pipe, therefore temperature changes do not occur rapidly. Because the temperature change does not happen rapidly, the average temperature between the initial and final temperature is often chosen for the modulus selection. Modulus values for PE 3608 (formerly PE3408) are given in Table 1 As longitudinal stress builds in the pipe wall, a thrust load is created on the end structures. This load can be significant and is determined by Equation 3. F = a A (3) where terms are as defined above, and F = end thrust, lb A = cross section area of pipe, in Equations 2 and 3 can also be used to determine the compressive stress and thrust (respectively) that is created when a temperature increase occurs. However, if the compressive thrust exceeds the critical longitudinal buckling force for the pipe segment, the pipe will deflect laterally. The critical force for a slender column can be determined using Euler's equation, assuming ends are free to rotate (which is conservative for restrained ends).

The applicability of Euler's equation for any specific pipeline calculation must be evaluated. For pipe installed on top of a surface (i.e. the ground, a pipe rack) pipe and fluid weight in the pipe and frictional forces increase the critical thrust force whereas in aerial applications weight and initial curvature due to deflection reduce the critical thrust force. While the amount of length change experienced by polyethylene pipe during thermal changes is greater than many other materials, the amount of force required to restrain the movement is less because of its lower modulus of elasticity.

The resulting pipe temperatures can be greater than the air temperature. To help reduce temperature changes resulting solar heating of a piping system, the pipe may be shaded or placed in a location that receives less direct sunlight. The effects of thermal expansion and contraction on a piping system can be controlled in several ways, including ❑ Lateral deflection expansion loops (snaking the pipe) ❑ Anchor and guide the pipe ❑ Conventional Expansion loops ❑ Expansion joints (non - pressures systems only) ❑ Burying pipes Bulletin: PP 814 -TN March 2007 Supersedes all previous publications Page 3 of 14 © 2007 Chevron Phillips Chemical Company LP Performance Pipe, a division of PO Box 269006 Phone: 800 -527 -0662 Chevron Phillips Chemical Company LP Plano, TX 75026 -9066 Fax: 972- 599 -7348 PERFORMANCE PIPE A o or Corm P;it te.1 (mow CisvrrorIP www.performancepipe.com Lateral Deflection Expansion Loops The simplest installation involves stringing pipe between end point anchor structures. If the pipe is simply laid in a straight Figure 1 Lateral Deflection line between the end anchors the pipeline anchoring structures must be capable of handling potentially high thermal contraction thrust loads during temperature decrease. During Lateral Deflect€ n temperature increase, the thrust force on the anchoring Total Deflection structure is limited by the pipe's critical thrust force. As the g temperature increases, the pipe exerts an increasing force on :..:..._. the anchor structures. In reaction, the anchor structures apply °"° " • an increasing compressive thrust on the pipe. When the critical I thrust force is reached the pipe undergoes elastic buckling and Length deflects laterally. The force on the anchoring structures decreases. To minimize these loads, pipe may be pre- snaked during installation rather than placed in a straight line. The critical thrust force may be calculated using Equation 4. Equation 4 is based on a column with no lateral support. Where frictional resistance acts to restrain lateral movement of the pipe such as pipe on the ground or in a rack, Equation 4 may under predict the thrust force. Snaked piping installations are also referred to as lateral deflection expansion loops. These loops can be used for DriscoPlex piping systems that are laid on the surface, supported or suspended above grade on hangers or in racks, or installed underwater. An effective flexible pipe expansion loop system employs the pipe's natural tendency to deflect laterally, and its high strain tolerance. Lateral deflection expansion loops are recurrent "S- curves" (snaking) along the piping runs that provide an initial lateral deflection, and allow pipe temperature changes to result in greater or lesser lateral deflection. The required number of "S- curves" (or equivalently the number of nodal points between curves) depends on how much lateral deflection is permitted. Surface and rack supported pipe systems designed with lateral deflection expansion loops must provide sufficient width allowance for lateral pipe deflection. The amount of lateral deflection is related to the anchor or guide spacing. Lateral deflection may be approximated by y =L I a4T (6) v 2 Where y = lateral deflection, in L = distance between endpoints, in a = thermal expansion coefficient, in /in / °F AT = temperature change, °F A long, semi - restrained pipe run can snake to either side of the run centerline.

Likewise, during thermal expansion, pipe that is pre- snaked requires less force than predicted using Equation 4 to continue snaking. At the time of installation, the anticipated temperature change from installation temperature to minimum temperature should be determined. Using this temperature change and the distance between points, determine lateral deflection, and install the pipe with this lateral deflection plus the minimum lateral deflection specified by the designer.

Anchored and Guided Pipe If the space required for lateral deflection expansion loops is not available, the pipe may be anchored at the end Figure 4 Typical Guides points and guided frequently enough so that snaking (column buckling) does not occur. This method results in longitudinal thrust and may require significant end anchoring structures. • For this discussion, anchoring restrains the pipe such that movement is not allowed in any direction, that is, longitudinal, lateral or vertical. Guides between the end anchors should allow the pipe to slide freely through the • guide. Fabricated fittings and rigid connections such as " flanges and transition fittings must be protected from bending, therefore if anchors are used to protect a fitting from bending stresses, all of the fitting outlets must be anchored. Anchored and guided piping systems require analysis of both the temperature increase and decrease.

The stress can be calculated using Equation 2. Tensile stress causes an end thrust at the anchors that can be calculated using Equation 3.

The tensile stress in the pipe should not exceed the allowable tensile stress determined from Equation 9. hallow = HDB f f (9) where aauow = allowable tensile stress, lb/in HDB = Hydrostatic Design Basis, lb/in (Table 1 -1, Chp. 6, Handbook of PE Pipe) f = environmental design factor (Table 1 -2, Chp. 6, Handbook of PE Pipe ) ft = service temperature design factor (Table 1-3, Chp. 6, Handbook of PE Pipe) A link to the Plastics Pipe Institute Handbook of Polyethylene Pipe is available on the Technical Library page of the Performance Pipe website. During temperature increase, the pipeline attempts to increase its length. The anchors prevent length increase, creating longitudinal compressive stress in the pipe and a thrust load against the anchors. Compressive stress can be determined using Equation 2 and should not exceed the allowable stress per Equation 9. (For convenience, the HDB value is used as a conservative value for allowable long -term compressive strength.) Guides must be placed at intervals not exceeding the column buckling length of the pipe per Equation 4. Combining Equations 3 and 4 yields Equation 10 for guide spacing.

When designing steel columns, a reaction load of 10% of the force that induces a longitudinal buckle of the column is used to resist lateral movement of the column and therefore resist buckling.

Typical expansion loop designs use fittings to create an offset and return to the original piping run. However, long runs of flexible polyethylene pipe would rather deflect laterally than push, so expansion loop designs should utilize guides that permit A longitudinal slippage, but not lateral deflection to direct length change to the expansion loop. Conventional fitting -style expansion loops are generally limited to piping systems where _- --- - - - - molded fittings are available. Large diameter fabricated fittings must be protected against bending and flexure stresses with cross bracing or other suitable means. The following protocol is for suspended expansion loops only. When designing conventional expansion loops, first determine the maximum length change from temperature change for the pipe run. The maximum run length change run may occur during expansion or contraction and can be determined using Equation 1. Next, determine the required leg length "A" for the loop. The "A -leg" length is determined from Equation 13 for a cantilever beam with a concentrated load. — D AL L = 1 2 (13) ` Sallow where LA = expansion loop leg "A" length, in OD = pipe outside diameter, in AL = length change In pipe run, In Ealpow = allowable bending strain for pipe with fittings, in /in (Table 2) The length of the "B -leg" is typically one half the "A -leg" length.

Buried Piping Systems A buried pipe is generally well restrained by soil friction along its length, and with moderate or low temperature change, soil friction alone is usually sufficient to prevent dimensional change and expansion movement. Therefore, a buried polyethylene pipe will usually experience, a change in internal stress rather than dimensional change and movement. A very significant temperature decrease may exceed soil friction <restraint, and apply contraction thrust loads to pipeline appurtenances. Thrust blocks for underground pipelines are usually not required unless great temperature change is anticipated. When transitioning from DriscoPlex pipe to bell and spigot style pipes such as ductile iron or PVC, the combination of thermal change and thrust load from internal pressure may cause sufficient contraction to pull apart the transition joint or other bell and spigot joints in the pipeline. The connection between the PE pipe • and the other style pipe needs to be restrained from longitudinal pullout.

The manufacturers of ductile iron and PVC pipe typically provide methods for calculating the number of joints that need to be restrained for a given axial force. If temperature change is extreme, low thrust capacity (unrestrained) connections to manholes may require longitudinal force thrust block (in -line anchor) protection. See Figure 6. The longitudinal stress from temperature change may be estimated using Equation 2. Soil load bearing capacity will require appropriate soils testing. Temperature changes below grade usually are not instantaneous, so an appropriate long -term elastic modulus from Table 1 should be selected. Figure 6 illustrates a typical thrust block design. Heat Transfer Polyethylene pipe may be heat traced, insulated, or both. Temperature limited (120 °F maximum) heat tracing tape should be used, and the tape should be installed over a pressure- sensitive metallic tape installed on the pipe. The metallic tape helps distribute heat over the pipe surface.
