6/3/2006 The history of the deflection limit is tied to unibell pvc pipe and their desire to break into the sabitary market in the 40''s. At the time 15% deflection was deemed maximum for the pipe. A factor of safety of 2 was applied, hence the 7.5% limit.

23/5/2008 RE: Deflection in PVC pipe rconner (Civil/Environmental) 16 May 08 15:20 If you are talking about unrestrained joints, you may want to check with who in the "jurisdiction" established the maximum deflection criteria (to find out exactly what their concern is).
Where: f = friction head of feet of water per 100'' for the specific pipe size and I.D. C = a constant for internal pipe roughness. 150 is the commonly accepted value for PVC and CPVC pipe. G = flow rate of gallons per minute (U.S. gallons). di = inside diameter of
PVC Pipe Deflection PVC Pipe Deflection In large water projects such as rural water and irrigation systems, both gasketed pipe joints and solvent cemented joints are quite common. Use of a plow, trencher, or backhoe may be used in pipe placement. Some pipe Puhui Pipe manufacturer in China
PVC pipe meets or exceeds all required health and safety standards and regulations governed by the U.S. and Canadian Safe Drinking Water Acts and other international statutes. Its use is monitored by independent agencies like NSF International — and Puhui Pipe manufacturer in China
When testing for allowable deflection limits, the minimum inside diameter should be used when establishing mandrel sizing. Puhui Pipe manufacturer in China Uni Bell PVC Pipe Association, 1998 4.

D3034/F679 (gravity pipe) limit PVC pipe deflection to 7½%, providing a 4:1 safety factor. On the other hand, DI pipe deflections are significantly limited by the linings used: • Cement mortar (gravity sewer and pressure water pipe) maximum allowable deflection is 3% due to potential
