Pigging is a significant part of a pipeline system that is required for production and operational maintenance. However, if the bend is not set properly, it is likely to cause congestion, which could cause the pipeline system to deviate from its normal operation or even lead to cracks or explosions due to overloaded stress. Due to the potential risk mentioned above, this report aims to build an...

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...

Conveying hard and the abrasive materials has been one of the major operational problems in industrial situations. The erosion of plant components, especially the pipe bends by abrasive solid particles of a fluid stream makes installation of pneumatic conveying systems a very costly affair for industry. Most users have either lived with the problem or have employed expensive bend materials to r...

The modernization of computer technology and commercial computational fluid dynamic (CFD) simulation has given better detailed results as compared to experimental investigation techniques. CFD techniques are widely used in different field due to its flexibility and performance. Evaluation of pipeline erosion is complex phenomenon to solve by numerical arithmetic technique, whereas CFD simulatio...

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...

Nowadays, the stress analysis mostly aimed at general buried pipelines. And few of the gas pipelines in tunnel (especially under the seismic action) were analyzed. Therefore, it is necessary to analyze the stress distribution of gas pipeline under seismic action in tunnel. In this paper, CEASAR II software was used to establish the stress model of China-Myanmar XX tunnel pipeline under seismic ...

As the process before transporting of capsule in a hydraulic pipeline system, capsule’s threshold motion is often tested horizontal straight pipe. However, result physical test this work shows that wheeled more easily start-moves bent Thus, numerical simulation and theory analysis were used to study The results demonstrate velocity magnitude water flow was asymmetric between inner part outer se...

Due to the periodic movement of the piston in the reciprocating pump, the fluid will cause 8 pressure pulsation, and the vibration of the pipeline will lead to instrument distortion, pipe failure 9 and equipment damage. Therefore, it is necessary to study the vibration phenomena of the 10 reciprocating pump pipeline based on the pressure pulsation theory. This paper starts from the 11 reciproca...
