In the present research, nonlinear vibration in a coupled system of Boron-Nitride nano-tube reinforced composite (BNNTRC) oil pipes is studied. Single-walled Boron-Nitride nano-tubes (SWBNNTs) are arranged in a longitudinal direction inside Poly-vinylidene fluoride (PVDF) matrix. Damping and shearing effects of surrounded medium are taken into account by visco-Pasternak model. Based on piezoele...

Liquid Natural Gas (LNG) processing facilities contain large complex networks of pipes of varying diameter and orientation intermixed with control valves, processes and sensors. Regular inspection of these pipes for corrosion, caused by impurities in the gas processing chain, is critical for safety. Popular existing non-destructive technologies that used for corrosion inspection in LNG pipes in...

Corrugated pipes used in sewage systems can be placed at high burial depths due to field conditions and exposed large ground loads. However, pipe safety underground loads is often overlooked. In corrugated design loads; the strength of pipes, quality soil around local are decisive enhanced Iowa formula for calculations. Underground loads, both bedding covering processes effective pipes. this st...

Recent advances in materials engineering are remarkable. New emerging the global market, and old ones constantly being improved. No exceptions for production of pipes. Nowadays cast iron, steel, reinforced concrete, ceramic, plastic other pipes used water supply sewage networks installation. Construction customers designers have to choose which use that they meet set requirements, easy maintain...
