HDPE PIPE DEFLECTION: THE BENDING STRESS PROBLEM

(Section 18 and M 294-98). Bending Stress is directly related to pipe deflection. Every pipe size exceeds HDPE’s bending stress limits of 3,000 psi (Figure 2) at deflection levels of 5% (1/3 less than the CPPA’s suggested maximum allowable deflection of 7.5%).
