The gas pipelines usually undergo complicated and changeable regional environment. As the level of the potential difference or pipeline’s route changes in the space and therefore elastic bending cannot meet the needs when pipe changes its direction, we generally use pipe bend to connect two pipelines with different spatial extend direction during the pipe laying period, and it can reduce the te...

Abstract Liquid oxygen supply pipeline is a key part of liquid kerosene engine test system. If leakage occurs, it will cause flow measurement error and affect the accuracy data. Therefore, in design pipeline, fluid solid thermal coupling simulation analysis method used to analyze stress “Z” bend, vessel bottom elbow balance device process ultra-low temperature flow, optimal laying scheme bend r...

Accident of oil and gas pipeline may result in enormous economic loss, great casualties and severe environmental pollution (Assael and Kakosimos, 2010). In the field of pipeline accident emergency, the Decision Support System (DSS) has been proposed to reduce the loss of an accident (Dey, 2001; Agbenowosi, 2000; Nataraj, 2005). However, their researches are mostly about risk management (Dey, 20...

In the oil and gas industry, pipeline is main mode to transport product can be applied for long-distance transportation; hence some pipe segments may buried underground. Buckling as cause of deformation failure often found at in-service during inspection activity. Changes in laying conditions such design operational parameters, human activity geological movement affect redistribution that lead ...

The pipeline combination scheme is optimized to reduce the cost of irrigation units in an economical microsprinkler system. With standard number segments branch and capillary pipes as decision variables, lowest pipe per unit area objective function, maximum pressure difference allowed system, minimum network, shape constraints, a hybrid genetic algorithm used calculate corresponding optimal pip...
