埋地输油管道热力计算方法探讨

Inquiring into the Thermal Calculating Method of Buried Oil Pipeline

在某些热油管道的热力计算中,并不能将管道周围土壤的有关物性参数当作常数处理。通过分析管道周围变物性土壤的热力工况,建立了相应的数学模型,根据数学模型,分析了有关计算公式和方法,最后,通过实例说明公式的具体应用。

In the thermal calculation of some heated oil Pipelines, it is impossible to treat those relative parameters of material in soil around pipelines as constant. Thus, a relevant mathematic model has been set up by analysing on the thermal cases of those varied substantial soil around pipeline and the relative calculating formula and method have been analysed based on this mathematic model. Finally, the practical application of formula have been introduced by examples.
