The designer, The Uni-Bell Handbook of PVC Pipe, fifth edition, covers this subject in Chapter 8, section 8. Several places have given the formula: $$\delta C = \frac {5 q L^4} {384 E I}$$ The Pipe on Supports calculator provides the designer with a way to determine support dimensions and the class of pipe needed to control beam deflection, beam stress and stress at supports. Pipe Deflections Tests have shown that flexible walled pipes (e. Am. 5 degree deflection. Spans are based on insulated and uninsulated lines below 650°F. Keeping pipe length in straight alignment with the previously laid length, insert spigot end into the gasketed bell until the reference mark is flush with the leading The liberal allowable deflection in the Fastite joint facilitates the installation of pipelines that include sweeping horizontal or vertical curves without the use of fittings. ASTM F2160 (2016) Standard Specification for Solid-wall High Density Polyethylene (HDPE) Conduit Based on Controlled Outside Diameter (OD) requires a minimum pipe stiffness at 5% deflection of inside diameter, when tested according to CAST IRON PIPE CO. Tests flexible pipe has been properly bedded and backfilled (ASTM D2321) Sized to . H. The maximum allowable deflection should only be used when the pipes will not move in service. anvilintl. Deflection (Δ) is defined as a relative displacement of the point from its original position. See AWWA C905 Section 4. 14" Performance Pipe — a division of Chevron Phillips Chemical Company LP — is the largest producer of polyethylene piping products in North America. Part 2 – Pipe (cont. 78 Figure 6. The rubber durometer chart below gives you an idea of the rubber hardness that you want for your application. ) 5. This decrease in vertical diameter is termed as the deflection, which is always expressed as a percentage. 078 0. All beam loads are for bending about Axis 1-1. A span chart may be created for standard pipe sizes or user entered data. S.
