Study explores space weather risk to natural gas pipeline in Finland

Risk-shifting, and Natural Gas Pipeline Regulation

risk assessment and management of gas transmission lines, in alamout natural gas pipeline

using natural gas as a clean, plentiful and inexpensive source of energy in recent years has progressively increased in iran. pipelines are the most common system to transport natural gas from field to different regions of iran. these pipelines always pose risks to surrounding population and environments. the aim of this study was to assess the potential health, safety, and environment risk of ...

Experimental Study of the Residual Stresses in Girth Weld of Natural Gas Transmission Pipeline

In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...

Comparison study on qualitative and quantitative risk assessment methods for urban natural gas pipeline network.

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...
