Gas Distribution Networks and Gas Transmission Networks
EPRG (European Pipeline Research Group) undertakes a wide range of research directed to increased integrity and safety of gastransmission pipelines. Corrosion, fit-for-purpose assessment and rehabilitation will constitute the major topics for existing pipelines, whereas for new pipelines in the ever-expanding European gas transmission grid, higher strength steels and higher hoop stress factors provide new challenges and opportunities for cost-effective pipeline construction and operation.
National Grid and Cadent want to establish best practice technologies and techniques to allow safe, reliable, efficient and economic use of the gas network with a reducing impact on the environment. By participating in EPRG, National Grid and Cadent have and will continue to benefit from the international experience of the other member companies’ representatives, while benefiting from significant leverage on project activity from the other member companies.
The benefits of participating in these European leveraged projects enable National Grid and Cadent to develop and implement best practice for a fraction of the full cost. Examples of completed projects include: State of the art review on pipeline resistance to earthquakes has raised awareness and understanding for future construction projects. Many of the projects of particular interest are on-going, i.e.delayed failure under constant pressure, performance of 3-layer PE coatings, the assessment of bending wrinkles, low bond line toughness girth weld defect acceptance criteria and the mechanical damage dent-gouge model.
