Pipelines carrying fluids and slurries are quite common. The third-generation pipelines carrying spherical or cylindrical capsules (hollow containers) filled with minerals or other materials including hazardous liquids are rather a new concept. These pipelines need to be designed optimally for commercial viability. An optimal design of such a pipeline results in minimum pressure drop in the pip...

In this paper, analytical and 3D numerical models are developed to investigate the mechanical behavior of sandwich pipe under internal pressure loading. The suggested provide an exact solution for stresses, strains displacement on pipe, which is made epoxy material core layer reinforced materials with alternate-ply skin layers. aim analysis evaluate potential applications jute pineapple leaf fi...

A pipeline is considered as shell structure so its design is based on stability concepts due to the exerted high pressure, local instability is probable to occur and so prevention of its occurrence and propagation are important subjects in its design. In this paper, dynamic buckle propagation has been modeled by 3D finite element method, results are verified with experimental tests and velocity...

In this article various pipes used for transporting of gas are introduced and pros and cons of each one are elucidated. The pipes are categorized in three different subgroups including metallic, polymeric and metallic-wire reinforced polymeric pipes. Metallic-wire reinforced polymeric pipes are nominated as the best option for usage in high pressure pipelines transporting natural gas. As a resu...

Pipeline is one of the main transportation ways with increasingly wide applications in various fields. Generally, pipelines are operated under high pressure, leakage accidents extremely dangerous and it necessary to ensure safety pipelines. In this study, a non-intrusive structure high-sensitivity based on fiber Bragg grating (FBG) sensing proposed for detection pipeline pressure. The core ditr...

Due to the formation of corrosion products, natural gas liquids and gas hydrates in long distance pipelines, timely and effective pigging operations are necessary to improve the gas transmission efficiency, reduce pressure loss, as well as guarantee the safe operation of gas wells, pipelines and networks. Gas transmission efficiency is a parameter to reflect the working condition and cleanlines...
