What is Bending Stiffness

The development of populated centers has as a consequence the corresponding increase of the consumption of resources, first of all of the consumption of energy necessary for the transport of the additional flows of water. Their often-limited character materializes the desire to redistribute existing resources in time and space, in accordance with the requirements of the uses served. The widespread introduction, due to competitive prices, of composite pipes, but for which there is insufficient information on their behavior over time, has led to the need to research the sustainability and reliability of new systems in development for water transport. This chapter aims to provide an efficient tool for those interested in managing water supply systems with direct reference to the reliability and sustainability of water transport systems: supply and distribution networks.
