| Abstract: | In oil and gas pipelines construction, a part of pipelines cross permafrost regions, which need higher thermal insulation technology. There is considerable disparity between China and foreign countries in this research field. This paper introduces the technology of domestic thermal insulated pipe prefabrication and field joint coating by taking Mohe-Daqing Crude Oil Pipeline as an example; the foreign insulation technology of supported and buried thermal pipelines by taking Trans-Alaska Pipeline System as an example; the new foreign thermal insulation technology development in aspects of materials, production line, thermodynamics analysis and software development. Finnaly it analyzes the problems existing in field joint construction and brings forward improvement suggestions. |
