WebJun 1, 2006 · Collapse failure is the result of geometric instability and not an overstress situation. For nearly all HDPE+HDD applications collapse can be avoided by limiting the pipe ovality or deflection to 7.5% and imposing an ovality compensation factor of 0.45 in the calculation of allowable net external collapse pressure. WebApr 18, 2024 · In this paper, a two-dimensional finite element analysis is used to investigate the peaking deflection of high-density polyethylene (HDPE) pipes. In the analyses, the …
