On the initial flaw sizes of uPVC pipe materials
Abstract
It is well known that flaws in unplasticized poly(vinyl chloride) (uPVC) pipes are generated during processing. The flaws include inclusions, gas bubbles, and results from poor fusion between PVC grains and extrusion additives. uPVC pipes are often used for water reticulation, subjected to an alternating pressure superimposed on a mean pressure. uPVC pipe samples have been found to fail in fatigue from a small semicircular flaw on the inside bore of the pipe. In designing uPVC pipes against fatigue failure due to pressure variation, it is essential to determine the initial flaw size. Truss attempted to estimate the lifespan of uPVC pipes and showed that predictions and experimental data are in good agreement.
