Description 308-318
In this study, the stress analysis of PE 100 grade high-density polyethylene pressure pipe squeeze-off has been carried
out using ABAQUS, a general-purpose finite element code. The squeeze-off phenomenon has been investigated for the
single and double squeeze-off pipes. In the finite element analysis, the true stress-strain curve of the material has been
adopted. The stress distributions in the squeezed pipe have been obtained. Special attention has been paid to the axial and
von Mises stress distributions along the pipe axis and around the squeeze-off ear. Finally, the practical implications of the
axial stress and von Misses stress distributions resulting from the squeeze-off phenomenon have been discussed and
correlated with the minimum distance away from the pipe welds, mechanical connections, local saddle joints, or nearest
squeeze-off locations imposed by related standards.
