Given the critical role played by natural gas in providing electricity, heat, and other essential services, better models are needed to understand dynamics of networks during extreme events. This paper aims at establishing appropriate fast simulation capture slow linepack depletion for ideal isothermal pipeline networks. Instead solving partial differential equations (PDE) on a large scale, thr...

The injection of pure hydrogen at a T-junction into horizontal pipe carrying natural gas is analysed computationally to understand the influence blending and geometry (diameter ratio, various 90° orientations) on mixing, for target 4.8–20% volume fraction blend. strongly inhomogeneous distribution within flow walls could indicate location potential material degradation including embrittlement e...

Natural gas station is an important part of the whole natural pipeline transmission system, in which vibration a hidden danger that cannot be ignored for safe operation station. In view severe enterprise, acceleration sensors are used to test each measuring point under different working conditions, and then three-dimensional finite element model established by using numerical simulation softwar...

For longer distances, natural gas is transported through transit pipeline at high pressures. In a place of consumption or at passing into a lower pressure pipeline, the pressure of the gas must be reduced. In Iran, the common procedure of reducing pressure in natural gas station is using expansion valves, which causes the waste of large amount of energy. Combined heat and power (CHP) systems ha...

With the fast development of urban transit system and natural gas industry, the Stray Current Corrosion (SCC) for buried gas pipeline has become more frequent in china. In this study, principle and characteristic of Stray Current (SC) resulting from rail transit system were introduced. Presently available SC testing methods, equipment and determination standards in china were summarized. For an...

In the oil and gas industry, the pipeline is a major component in the transmission and distribution process of oil and gas. Oil and gas distribution process sometimes performed past the pipeline across the various types of environmental conditions. Therefore, in the transmission and distribution process of oil and gas, a pipeline should operate safely so that it does not harm the surrounding en...
