Method for levelling the temperature of an electrically heated pipeline
专利汇可以提供Method for levelling the temperature of an electrically heated pipeline专利检索，专利查询，专利分析的服务。并且A method for minimizing temperature gradients in a fluid being transported through an elongated electrically heated pipeline comprises the independent circulation of a heat transfer fluid through at least one tracing tube arranged either internally or externally along the length of the pipeline simultaneously with the application of electrical energy to the pipeline to heat the transported fluid. The heat transfer fluid has a high heat transfer coefficient. The quantity of heat transfer fluid circulated through the tracing tubes is small (about 1 percent in the case where both the transported fluid and the heat transfer fluid are liquids) in comparison to the amount of transported fluid passing through the pipeline on a volume per unit length basis. In one arrangement a single pump circulates the heat transfer fluid through serially connected tracing tubes arranged along the length of the pipeline. In another arrangement, the heat transfer fluid is reciprocated alternately through a single tube extending longitudinally of the pipeline by pumps and associated holding tanks arranged at both ends of the tube.，下面是Method for levelling the temperature of an electrically heated pipeline专利的具体信息内容。
