Abstract

The extra quantities of wastewater entering the pipes can cause backups that result in sanitary sewer overflows. Urban underground infrastructure monitoring is important for controlling the flow of extraneous water into the pipelines. By combining the wireless underground communications [...]

Abstract

This paper describes how pipelines are often located in seismic unstable slopes where earthquake-induced movements may cause their collapse. Thus, the analysis of the soil-pipe interaction plays a large role for the seismic hazard prevision. This paper deals with an analytical approach [...]

Abstract

Hydraulic steel structures, especially lock gates play a significant role in keeping navigation traffic uninterrupted. After a few decades of operation, many of the welded joints may suffer various degrees of deterioration, primarily due to fatigue. To economically combining crack [...]

Abstract

This work presents the design of a folded Krüger device under realistic geometrical requirements for a wing with hybrid laminar flow control (HLFC). A focus is laid on the investigation of the trade-off between space allocation of the retracted Krüger and the aerodynamic high-lift [...]

Abstract

International audience; The application of robots for the inspection of pipelines are of greater significance in industries such as nuclear, chemical and sewage. The major problem in the design of these robots lies in the selection of a suitable locomotion principle, selection of [...]

Abstract

Simulation of the welding of two dissimilar materials, stainless steel and mild steel, has been carried out using finite element together with experiments to validate the method and better understand the transient temperature profiles and the stress distribution in a cladded pipe. [...]

Abstract

The stress analysis is presented for the proposed loop seal modification to the LOFT Steam Generator Main Feed Piping. THE SAP IV finite element computer program was used to analyze normal, upset, emergency, and faulted conditions. Results of the analysis indicate that the modified [...]

Abstract

Internal inspection of pipelines is an important tool for ensuring safe and reliable delivery of fossil energy products. Current inspection systems that are propelled through the pipeline by the product flow cannot be used to inspect all pipelines because of the various physical barriers [...]

Abstract

The United States economy is heavily dependent upon a vast network of pipeline systems to transport and distribute the nation's energy resources. As this network of pipelines continues to age, monitoring and maintaining its structural integrity remains essential to the nation's energy [...]

Abstract

The S-Farm overground transfer (OGT) line will bypass the existing line(s), between valve pits 241-S-B and 241-S-D that no longer meet system requirements. The new OGT line will provide a waste transfer pipeline between these valve pits in support of saltwell pumping activities. The [...]
