9 Allowing for length changes in Natural PP pipelines PP-n Natural PP-BCF /IR General Variations in temperature cause greater length changes in thermoplastic materials than in metals. In the case of aboveground, wall or duct mounted pipework, particularly where subjected to varying working temperatures, it is necessary to make suitable provision for length changes in order to prevent additional stresses. Length changes can be taken up by the following means: a. Flexible sections b. Expansion joints The flexible section is used most frequently, as it is the simplest and most economical method. The calculation and positioning of flexible sections are, therefore, described in detail. Coefficient of linear expansion α of various materials x St Cu GFK AI PVC PP PE Calculation and Positioning of Flexible Sections Fundamentals It is possible to take advantage of the very low modulus of elasticity of PP by including special sections of pipe which compensate thermal length changes. The length of the flexible section mainly depends upon the pipe diameter and the extent of the length change to be compensated. In order to simplify planning and installation, the third influencing factor the pipe wall temperature is not taken into account, particularly as installation usually takes place in the temperature range between 5 and 25 C (4 and 77 F). Where the pipework changes direction or branches off there is always a natural flexible section. Movement of the flexible section a caused by the length change l must not be impeded in the area concerned by too tightly mounted pipe brackets, jutting brickwork, girders or similar. Modulus of elasticity of various materials E 20 x 3 kp/cm St Cu AI GFK PVC PP PE min. distance = I max. +5 mm.20 in. min. distance = I max. +5 mm.20 in.

10 Determining the Length Change ( L) (Example ) In order to determine the length of flexible section required, the extent of the length change must be ascertained first of all, by means of the following formula where L = L T δ (mm) = (m) ( C) (mm/m C) or (inch) = (inch) ( C) (inch/inch C) or (inch) = (inch) ( F) (inch/inch F) L = length change in mm or inches. L = length in m or inches of the pipe or pipe section where the length change is to be determined. T = difference between installation temperature and maximum or minimum working temperature respectively in C (or F). δ = coefficient of linear expansion of the pipe material in mm/m C, (inches/inch C), or inch/inch F (see tables below). Values for δ 0.5 mm/m C or inch/inch C or inch/inch F The length change can also be taken directly from diagram as shown on the following pages. Important: If the working temperature is higher than the installation temperature the pipe becomes longer. If, on the other hand, it is lower than the installation temperature, the pipe becomes shorter. Therefore: the installation temperature as well as the maximum and minimum working temperatures must be taken into account. Installation temperature working temperature > installation temperature working temperature < installation temperature The procedure is explained using a coolant pipe as an example: Length of the pipe from the fixed point to the branch where the length change is to be taken up: L = 8 m (35 inches) Installation temperature: Tv = 5 C L F fixed point - I + I Temperature of the coolant: T = -2 C Temperature when defrosting and cleaning: T 2 = +35 C Material: PP F fixed point F fixed point L = 8 m Contraction during service with coolant: L = L T δ = 8 27 (.5) = 32.4 mm (.0005) =.28 in. Expansion during defrosting and cleaning: + L 2 = L T2 δ mm (.0005) =.94 in. Important: Difference in temperature T = T v T = 27 C T 2 = T 2 T v = 20 C. It is of advantage to indicate pipe expansion with "+" and contraction with " ". 2. The greater length change is applicable for determining the length of the flexible section. Determining the Length of the Flexible Section (a) (Example 2) The values required to determine the length of the flexible a section are: The maximum length change L, in comparison with the zero position during installation, (which can be either an expansion or a contraction), and the pipe diameter d. If values a and d are known, the extent of the maximum length change L to be compensated can be taken from table for specific lengths of flexible section a. If values L and d are known, diagram 2 (on the following page) for optional length changes shows the length of flexible section a required. L = 8 m (35 inches) - I a + I2.

11 In example, if the pipe to be installed is d = 50 mm, the length of flexible section required, i.e.250 mm, can be taken directly from diagram 2, based on the maximum length change of L, = 32.4 mm (.28 in.). - L=L T δ= =32.4 mm = (.0005) =.28 in. Installation Hints The length changes in pipework sections should be clearly controlled by the arrangement of fixed brackets. It is possible to distribute the length changes in pipework sections by suitable positioning of fixed brackets (see adjoining examples). If it is not possible to include a flexible section at a change of direction or branch, or if extensive length changes must be taken up in straight sections of pipework, expansion loops may also be installed. In this case the length change is distributed over two flexible sections. For an expansion loop, (taking example ), the length change of 32.4 mm (.28 in.) would require a flexible section length of a = 830 mm (32.8 in.). A single flexible section on the other hand, would need to be 250 mm (49.2 in.) in length. PP-n Natural PP-BCF /IR 3. If, on the other hand, the flexible section is pre-stressed to L/2, the required length of flexible section is reduced to approx. 0 mm (59 in.). The length change, starting from the zero position, then amounts to ± L/2 = 97.5/2 (3.84/2) = mm (.92 in.). In special cases, particularly at high working temperatures, pre-stressing of a flexible section improves the appearance of the pipeline in service, as the flexible section is less strongly deflected. L L F not recommended F L/2 /2 L L/2 L/2 L/2 L/2 F L recommended L/2 In particularly difficult cases, where the length changes are large and acting in one direction only, it is also possible to pre-stress the flexible section during installation, in order to reduce the length of a. This procedure is illustrated in the following example: Installation conditions: L = m (394 in.) d = 50 mm (-/2 in.) Installation temperature: 5 C Max. working temperature: 80 C Material: PP. Length change + L = L T δ = 5 (.5) = 97.5 mm (.0005) = 3.84in. 2. Flexible section required to take up length change of L = 97.5 mm (3.84 in.) according to diagram: a = approx mm (78.7 in.). F L/2 L/2 F F F L = m L = m - L/2 L F a = 2 m L/2 a =,5 m

15 The Incorporation of Compensators (Expansion joints) Due to the low modulus of elasticity of PP, the reaction force of a plastic pipe when subjected to variations in temperature is slight in comparison with metals. The normal expansion joints intended for metal pipes are, therefore, as a rule unsuitable, due to their high resistance. For this reason, only easily functioned expansion joints may be incorporated in plastic pipework, i.e. those with a low resistance. In this respect the following types may be considered: rubber expansion joints, PTFE corrugated expansion joints, or if chosen suitably, metal multi-disc expansion joints. PP-n Natural PP-BCF /IR The Incorporation of Valves Valves should be mounted as direct as possible, i.e. they should be formed as fixed points. The actuating force is thus transmitted directly, and not through the pipeline. The length changes, starting from the valve, are to be controlled as described previously. For safe mounting of plastic valves, George Fischer valve brackets or George Fischer valves equipped for direct mounting are especially suitable. When fitting an expansion joint, the pipe must be regulated with fixed points so as to ensure perfect functioning under working conditions. The installation temperature is used as the basis for this. In pipe sections with expansion joints the pipe bracket spacing given in the section on support spacing may on no account be exceeded. Where expansion joints are incorporated in vertical pipe runs the pipe bracket spacing given for horizontal pipelines is applicable. The Installation of Pipework under Plaster or Embedded in Concrete Padded Pipework Where pipework installed under plaster or embedded in concrete changes direction or branches off, the flexible section under consideration must be padded along the length a, which is based on the calculated length change. The accompanying tees or elbows must, of course, also be included in the padding. Only flexible materials, such as glass wool, mineral wool, foam plastic or similar may be used for padding.

16 Pipe bracket support centers and fixation of plastic pipelines General PP pipelines need to be supported at specific intervals, depending upon the material, the average pipe wall temperature, the specific gravity of the medium, and the diameter and wall thickness of the pipe. The determination of the pipe support centers has been based on the permissible amount of deflection of the pipe between two brackets. The pipe bracket centers given in Table are calculated on the basis of a permissible deflection of max cm (0.0 inch) between two brackets. Pipe bracket spacing in the case of fluids with specific gravity g/cm 3 as well as for gases Table The pipe bracket spacing given in the table may be increased by 30% in the case of vertical pipe runs, i.e., multiply the values given Material d Pipe bracket intervals L in cm at: and PN mm inch 20 C 30 C 40 C 50 C 0 C 80 C 0 C 20 / / / PP / PN In the case of a vertical pipe run the pipe bracket spacing given in the table may be increased by 30%, i.e. multiply the values given by.3. Pipe bracket spacing in the case of fluids with specific gravity > g/cm 3 Where fluids with a specific gravity exceeding g/cm 3 are to be conveyed, the pipe bracket centers given in Table must be multiplied by the factors given in the second column of Table 2, resulting in shorter distances between the supports. Table 2 Specific gravity of the fluid in g/cm Factors for pipe bracket centers in the case of spec. gravities > gm/cm

17 Installation of closely spaced pipe brackets A continuous support may be more advantageous and economical than pipe brackets for small diameter horizontal pipework, especially in a higher temperature range. Installation in a V - or "U"-shaped support made of metal or heat-resistant plastic material has proven satisfactory. PP-n Natural PP-BCF /IR Sliding or hanger type brackets permit movement of the pipeline in various directions. A sliding block attached to the base of the pipe bracket, when on a flat supporting surface, allows movement as required. When the pipe run changes direction, sliding or hanger type brackets are necessary at given points in order to maintain free movement of the pipe. Pipe bracket requirements When mounted, the inside diameter of the bracket must be greater than the outside diameter of the pipe, in order to allow length changes of the pipe at the specified points. The inside edges of the pipe bracket must be formed in such a way that no damage to the pipe surface is possible. George Fischer pipe brackets meet these requirements. They are made of plastic and may be used under rugged working conditions and also in areas where the pipework is subjected to the external influence of aggressive atmospheres or media. George Fischer pipe brackets are suitable for PVC, CPVC, PE, PP and PVDF pipes. Installation examples using George Fischer pipe brackets Short center to center distances due to small overall dimensions of the George Fischer pipe bracket and the George Fischer shell coupling. Arrangement of fixed brackets If the pipe bracket is positioned directly beside a fitting, the length change of the pipeline is limited to one direction only (one-sided fixed point). If it is, as in most cases, necessary to control the length change of the pipeline in both directions, the pipe bracket must be positioned between two fittings. The pipe bracket must be robust and firmly mounted in order to take up the force arising from the length change in the pipeline. Hanger type brackets are not suitable as fixed points. Arrangement of loose brackets Axial movement of the pipeline must not be impeded by fittings positioned next to the pipe bracket or by any other change in the pipe diameter.
