Sharing of common corridors by gas pipelines and overhead power transmission lines is becoming quite common. Voltages can be induced on gas pipelines from power transmission lines in the sections where they share the corridor. This paper reports on a recently completed study on the interaction between gas pipelines and power transmission lines in a utility common corridor in New South Wales, Au...

A series of high-density polyethylene/Cloisite 20A/graphite nanocomposites were prepared via melt blending for the production of polymeric pipes for natural gas transfer. The microstructural, mechanical, thermal, electrical and barrier properties of prepared nanocomposites were investigated. An intercalated morphology was observed for prepared nanocomposites. Improved mechanical properties ...

Sir Humphry Davy witnessed the first chlorine hydrate crystallizing in 1811. Couple of century later his discovery, natural gas hydrates has begun to play an important role in energy business. From being a mere chemical curiosity, they have proven to be a nuisance for the natural gas industry. The problem of hydrate induced blockage in “wet gas” flow systems has been widely reported and became ...

from the perspective of theorists of international relations including functionalists and regionalists, establishment of cooperation and economic, commercial and transportation relations is among the suitable methods for fostering integration in international relations and deepening friendship, peace and stability particularly among regional countries. considering this fact, the authors believe...

A leaking water pipe bursting high pressure water jet in the soil will create slurry erosion which will eventually erode the adjacent natural gas pipe, thus causing its failure. The standard 300 mm safety distance used to place natural gas pipe away from water pipeline facilities needs to be reviewed to consider accidental damage and provide safety cushion to the natural gas pipe. This paper pr...

The approval by FERC of a regulated natural gas pipeline’s market-based rate application depends upon the availability of substitute pipelines with sufficient capacity to maintain the current transport price. But how much alternate capacity is enough? Clearly, the price will not increase when alternate pipelines have unsubscribed capacity equal to the capacity of the applicant pipeline, since t...

In this paper, a qualitative and a quantitative risk assessment methods for urban natural gas pipeline network are proposed. The qualitative method is comprised of an index system, which includes a causation index, an inherent risk index, a consequence index and their corresponding weights. The quantitative method consists of a probability assessment, a consequences analysis and a risk evaluati...
