Radioactivity in the gas pipeline network in Poland

Journal of Environmental Radioactivity, 2020
<p>The radiological risk in natural gas industry is mostly connected with radon (Rn-222) and its progeny: Po-218, Pb-214, Bi-214, Po-214 and Pb-210. The radon activity concentration in natural gas transported by gas pipelines varies in a wide range from dozens of Bq/m<sup>3</sup> to several thousand Bq/

Dynamic failure behavior of buried cast iron gas pipeline with local external corrosion subjected to blasting vibration

, 2021
The buried corroded cast iron gas pipeline is more likely to be damaged by engineering blasting vibration. Therefore, it is of great significance to study the dynamic response and realize the safety control of the buried corroded gas pipelines under the ...

STATE OBSERVERS FOR MONITORING GAS PIPELINES

IEE Proceedings D Control Theory and Applications, 1983
The paper describes work performed in collaboration with the British Gas Corporation, in relation to the development of algorithms for monitoring the condition of high-pressure gas pipelines. The practical problem considered is that of reconstructing the pressure profile along a single length of pipe from pressure measurements at the end points and a ...

Sour Gas Pipelines

Offshore Technology Conference, 1988
ABSTRACT An incident with a sour oil pipeline some 15 years ago was responsible for defining the measures necessary to give protection from hydrogen induced and sulphide stress cracking (HIC and SSCC) for pipelines in simmilar duties.

Seismic vulnerability of natural gas pipelines

Reliability Engineering & System Safety, 2013
Abstract This work deals with the analysis of the interaction of earthquakes with pipelines transporting and distributing natural gas for industrial and civil use. To this aim, a new large data-set of seismic information classified on the basis of selected seismological, geotechnical and structural parameters is presented and analyzed.

Supply reliability assessment of a gas pipeline network under stochastic demands

Reliability Engineering & System Safety, 2021
An integrated methodology to assess the gas supply reliability of a gas pipeline network considering stochastic demands is proposed in this study. Typical scenarios are selected based on the structural reliability calculated by probability theory and ...

H2 in an Exisiting Natural Gas Pipeline

Volume 1: Pipeline and Facilities Integrity, 2020
Abstract N.V. Nederlandse Gasunie (Gasunie) has converted an existing gas transmission line from transporting natural gas to transporting a mixture of gaseous hydrogen and 30% to 0% methane. To enable this, an assessment was carried out on technical safety, process safety, work safety and external safety.
