Cast irons pipeline are usually old pipelines, these can be modelled in Ple4Win as articulated pipelines. Ovalisation of the pipelines are calculated, as are stresses in the pipe, both results can be used to check whether the pipe will crack or implode. Furthermore, Ple4Win will check the movements and rotations in the joints and warn if leakages or freeze-up’s (danger of fragments splintering off at the rim) occur at any connection.
