2013/04/17· roximate Pipe Stiffness (PS) for Solid-Wall HDPE DR Pipe It is occasionally convenient to know PS values for solid-wall OD-controlled HDPE pipes made to common dimension ratios (DR’s). The table below was developed using Eq. 1, and assumes pipe having average outside diameter, minimum wall thickness, and made using HDPE material having 110,000 psi short-term modulus of elasticity.
