| 摘要： | A number of projects concerning continental links for the transport of treated natural gas over long distance, both on and offshore, have been implemented during the last few years or are currently being Implemented. The long trunklines in North America and subsea trunk lines planned or already in operation in the North Sea (Norpipe, Statpipe, Zeepipe and Europipe to deliver the gas from the Norwegian Sector to Europe), are outstanding examples of such long distance transmission of gas in large diameter pipelines operated at high pressure The development of such network has paid special attention to the effects that low temperature resulting from the transportation process may Imply In terms of pipe structural integrity and environmental impact • ' Scope of this paper is to discuss operating limitations due to low gas temperature. New project scenarios are presented In a brief Introduction. The fluido-thermo-dynamic background for the development of low temperatures are outlined. Finally some topics relevant to structural Integrity are discussed, in particulan the pipe steel behaviour at low temperature, the prediction techniques of the Ice bulb growth around the pipe, the interactions of the cold line with the soil and the consequences due to the differential compliancy of the pipeline towards points of fixity (in-line valves/tees or fixed plants). |
