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.
Young’s Modulus is also known as tensile modulus, elastic modulus or modulus of elasticity. When a stretching force (tensile force) is applied to an object, it extends, and its behavior can be obtained using stress-strain curve in the elastic deformation region (Known Hooke’s Law).
LONG TERM PIPE DEFLECTION Since the test materials included HDPE, PVC and ABS pipes and the test pipe sizes consisted of 300 and 400 mm, nondimensional deflection and pipe stiffness (PS) calculated at 5.0% deflections were used for the presentation.

This is the third edition of the Method for Prediction of Flexible Pipe Deflection. The first edition, released May 1, 1997, was prepared by Amster K. Howard (soils specialist), Leo A Kinney, Jr. (pipe specialist), and Richard P. Fuerst (pipe specialist). The equations
Critical Buckling Pressures are calculated using the Modulus of Elasticity (400,000 PSI for PVC and 28,200 PSI for HDPE), and published Poisson''s Ratio for the given material [Unibell Handbook of PVC, 5th Edition & Handbook of Polyethylene Pipe, 2nd Edition].

The modulus of elasticity (E) is dependent upon the material that the pipe is produced from (HDPE, HDPE, etc.). The moment of inertia (I) is dependent on the pipe wall geometry. The soil stiffness is primarily controlled by the modulus of soil reaction (E’) of the backfill that surrounds the pipe.

The first PE pipe material used in engineering appliions was Type 50 High Density PE (HDPE) with a long term stress of 50MPa. Subsequently, Medium Density (MDPE) materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth resistance and crack propagation resistance.
