The flow of molten poly(ethylene terephthalate) in pipes is discussed. The considerations made are based on the results of previous investigations by the authors, concerning the rheological behavior of the melt which exhibits thermal degradation. A procedure is proposed which enables the design of a pipe‐line system for the distribution of molten, spinnable poly(ethylene terephthalate) in a fiber plant to be made.
