Original Abstract

Plastic pipe producers are forced by various initiatives to increase the content of recycled material in their products. The performance of the recycled material is worse than the performance of the virgin material. That is why plastic pipes made entirely of recycled material are now allowed for non-pressure applications only. It would be theoretically possible to use the recycled material in pressure applications as a part of multilayer pipes. In this contribution, lifetimes of both multilayer and single-layer pipes containing recycled materials are estimated to see, if the presence of recycled material layer in the pipe wall reduces the lifetime significantly. Several possible designs are considered. Test data from cracked round bar (CRB) tests on the recycled material are used as an input for the lifetime estimation. The lifetime estimation is carried out using FEM modelling of different loading cases and integration of the power law that describes the crack growth rate.
