Reliability of PVC-U Three Layer Pipes with Recycled Solid Core

Papers # 2010 Vancouver

In order to make clear the reliability of PVC-U recycled pipes in relation to the three-layer structure, we described the deformation and fracture mechanism of wall of pipes based on non-destructive techniques of scanning acoustic microscopy (SAM). The results showed that the multiple necking deformation occurred after the multiple cracking/crazing of which initiated from not well melting powders in recycled core. These mechanisms prevent the brittle fracture of recycled pipes.
