Abstract Buried oil and gas pipelines may face the threat of geological disasters such as landslides, faults, floods. However, long‐term buried often have corrosion defects, which bring greater challenges to safe operation pipelines. In this study, via finite element analysis method validated by testing results, blasting pressure a middle‐high strength pipeline with defects under an axial compr...

In this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. To analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. Because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...

Context. Software development pipelines are used for automating essential parts of software engineering processes, such as build automation and continuous integration testing. In particular, interactive pipelines, which process events in a live environment such as an IDE, require timely results for low-latency feedback, and persistence to retain low-latency feedback between restarts. Inquiry. D...

Complex computational pipelines are becoming a staple of modern scientific research. Often these pipelines are resource intensive and require days of computing time. In such cases, it makes sense to run them over high performance computing (HPC) clusters where they can take advantage of the aggregated resources of many powerful computers. In addition to this, researchers often want to integrate...

Abstract The formation, propagation, and detection of fatigue cracks are the key issues for life extension pressure pipelines metal welded joints. Especially in high-temperature high-pressure water environment nuclear power. Since interference measuring instruments noise would affect monitoring potential signals that characterize crack growth. Combined with relevant information various methods ...
