With the rapid development of natural gas pipeline, the safety of natural gas pipeline is paid more and more attention to. This paper presents a new safety assessment model based on fault tree and fuzzy neural network. Firstly, in the light of fault tree theory, fault tree analytical figure is established for buried natural gas pipeline system and the index system is established about buried na...

Thanks to recent progress in satellite-based remote sensing technologies and object oriented image analysis, as well as to the availability of new very high-resolution sensors, it is now possible to design gas pipeline monitoring systems, as has been demonstrated by the co-funded European “PRESENSE Pipeline REmote SENsing for Safety and the Environment” project. In parallel, the European Space ...

the risks of fire and explosion in oil and gas industry need to be managed. the objectives of the present study were to assess the risk of fire and explosion in iso-max unit of tehran oil refinery using dow’s fire and explosion index and to study the influences of the controlling methods. the latest version of dow fire and explosion index guideline was applied to calculate the fire and explosio...

Detection of Metal Defects on Gas Distribution Pipeline by Remote Field Eddy Current (RFEC) Using Finite-Element Analysis — It is necessary to find out whether there are metal defects on underground gas distribution pipelines without excavation in order to establish safety strategies for replacement or maintenance. The metal defects are classified into general corrosion, stress corrosion cracki...

This paper explores the effects of an abrupt cross-section area change gas pipes on propagation law explosion. For this, explosion pipe experimental system was established, and a numerical research conducted. By simulation, evolution overpressure, temperature, vorticity, kinetic energy shock waves in pipelines investigated. allowed us to obtain expressions for attenuation coefficient, increase ...

There must be few other situations where there are eager purchasers of natural gas (India and Pakistan), willing suppliers of natural gas (Turkmenistan, Iran, Qatar and Oman), and yet, no pipeline. The distances involved are modest, and techno-economic viability appears straightforward. This paper examines in detail the policy, technology, and economics of an overland pipeline supplying natural...

This special report looks at the use of natural gas pipeline compressor stations on the interstate natural gas pipeline network that serves the lower 48 States. It examines the compression facilities added over the past 10 years and how the expansions have supported pipeline capacity growth intended to meet the increasing demand for natural gas. Questions or comments on the contents of this art...
