Abstract

This paper reports on some aspects of a ENI Group feasibility study of high pressure (> 100bar) - high strength pipelines designed for transportation of large quantities of naturalgas over long distances (> 2500 km). The experimental results obtained in collaborationwith Centro Sviluppo Materiali (CSM) and ILVA L.T. clearly showed the full reliability ofmodern high strength linepipe materials of X70-X80 grade, with respect to fracturebehaviour, even at low temperature, in very high pressure regimes.
