专利汇可以提供Pipeline system专利检索,专利查询,专利分析的服务。并且A pipeline system, designed particularly for transporting liquid natural gas (LNG) is provided, comprising modular sections of insulated pipe, each modular section having an outer pipe and an inner pipe which is compressed and secured by means such as stress cones to the outer pipe, thermal insulation preferably being provided in the annular space between the inner and outer pipes. Such stress cones are provided at end portions of each modular section and function to transfer the compressive load from the inner pipe to a tension load on the outer pipe, thermal insulation also preferably being provided between the connection of each stress cone to the inner or outer pipe. When LNG is passed through the inner pipe at low temperatures, of the order of -258*F, contraction of the inner pipe which is under compression will be resisted by the physical connection to the outer pipe. The compression in the inner pipe is maintained by tension in the outer pipe, which can be at about ambient temperature, so that overall contraction of the system due to temperature decrease of the inner pipe is minimized.,下面是Pipeline system专利的具体信息内容。
