92 AHEAD OF THE FLOW ® Expansion and Contraction of Plastic Pipe (Continued) Where: ΔL = Dimensional change due to thermal expansion or contraction (in.) Y = Expansion coefficient (in/10°F/100ft) (See Table on previous page) (T1-T2) = Temperature differential between the installation temperature and the maximum and minimum system temperature, which ever provides the greatest differential (°F) L = Length of pipe run between changes in direction (ft) Example 1: How much expansion can be expected in a 200 foot straight run of nominal size 3 PVC Pipe that will be installed at 75°F when the piping system will be operated at a maximum of 120°F and a minimum of 40°? ΔL = 0.360(120 - 75) x 200 10 100 ΔL = .360 x 4.5 x 2.0 = 3.24 inches Stresses and forces that result from thermal expansion and contraction can be reduced or eliminated by providing for flexibility in the piping system through frequent changes in direction or introduction of loops as graphically depicted in the figures below. Normally, piping systems are designed with sufficient directional changes which provide inherent flexibility to compensate for expansion and contraction. However, when this is not the case or when there is reasonable doubt as to the adequate flexibility of the system, expansion loops or expansion joints should be designed into the system. If an expansion loop (which is fabricated with 90° elbows and straight pipe as depicted in Fig. 1) is to be used, the leg length (R) should be determined by using the following formula to insure that it is of sufficient length to absorb expansion and contraction movement without damage. R = 1.44 √DΔL Where: R = Expansion loop leg length (ft) D = Nominal outside diameter of pipe (in) ΔL = Dimensional change due to thermal expansion or contraction (in) NIBCO INC.

R = 1.44 √DΔL Flexibility, through the introduction of flexural off-sets, must be inserted into a piping system design in situations where straight runs of pipe are long or the ends of a straight run are restricted from movement and also in situations where the system is restrained. Several examples of methods for inserting flexibility in these situations are graphically presented below. In each case, rigid supports or restraints should not be placed within the leg length of an expansion loop, off-set, or bend. Fig. 1 Fig. 3 Fig. 3 Fig. 4
