  Abstract

The use of Glass Fiber Reinforced Polyester (GFRP) pipes in the industry increased considerably in the past decades. These pipes are used in various applications such as conveying water, sewage, seawater, industrial wastewater, petroleum and also in power plants and chemical industries. These pipes are resistance to corrosion resistance and thus they are exploited for long-term purposes. Unlike metals, creep occurs in polymeric materials at any temperature. GFRP pipes are generally designed to withstand against the internal pressure and also transverse compressive force as the two main load cases. Design architecture of composite layers, i.e. number of layers and their fiber orientations, is done based on the initial response of the pipe structure to the aforementioned loadings known as short-term behavior. But evaluating the long-term performance of the pipes is one of the important design requirements according to the working life of these pipes. In this study, the long-term behavior of a GFRP pipe undergoing transverse loading is investigated experimentally and theoretically. The influence of structural parameters including the thickness of liner, lay-up orientation and number of layers are evaluated.
