Rapid recovery of old steel piping capacity with energy saving effect by reducing hydraulic resistance values

Abstract

The design of repair work for the reconstruction of pressure steel pipelines using Swagelining technology by pulling pre-compressed polymer pipes into old pipelines is considered. Information on regulatory and technical documentation and the field of application of advanced technology, on installation and operation conditions, as well as on the comparative assessment of energy consumption after reconstruction of dilapidated sections of pipelines with polymer pipes with the possibility of minimizing energy consumption during water transportation under conditions of non-thermal operation of the pipeline with changes in hydraulic characteristics is presented.
