THE VALUE OF FRP PIPE FLEXIBILITY

This article examines the use of fibre-reinforced polymer (FRP) composites in pipeline transport applications, highlighting the advantages of these materials in terms of mechanical performance and durability. The properties and classification of FRP materials, manufacturing processes, joint types, and above-ground and underground installation solutions are analysed. In addition, reference is made to the ISO 14692 regulatory framework used to assess pipe flexibility, including experimental investigations of mechanical behaviour through tensile and bending tests. The last part of the study presents analytical models and numerical simulations designed to determine maximum stress and displacements, with the results obtained demonstrating compliance with the requirements of relevant international standards.
