In the reported study laboratory tests on PE pipe samples were conducted. After squeezing the samples were subjected to hydrostatic stress rupture tests in a water-Igepal solution. Because of the limited scope of the research, the independent effects of each of the squeeze-off variables could not be determined and the results are not conclusive. However, the data showed some trends. The amount of wall compression and the squeeze tool geometry can be major contributors to the performance of the pipe.
Slow squeeze is beneficial, possibly because the induced stress is lower.
Duration of the squeeze showed only limited influence on performance. For good materials, diameter of the pipe did not influence the after-squeeze performance.
