成品油管道输送油品温升分析

成品油在输送过程中出现油品温度升高的问题，当输送介质为轻质油品且输量增大时，温升可能产生严重的危害，包括油品发生损耗，油品质量降低，污染环境及管道产生很大的热应力等。这是在成品油管道的设计和运行中必须要考虑的问题。

Analysis on Temperature Increment of Oil Product in Oil Product Pipeline System

The temperature of oil product will increase when transporting in pipeline system,which is mainly caused by pumps' operatioin,restriction devices and fluid flowing along the undulated pipelines. The temperature increment in the transportation period is extremely harzadous to light-end products, especially when throughput rate increases,which makes the oil products transported loss,quality of the oil products degrade and environment pollute,and even more the severe heat stress yields on pipeline induced by tem- perature increment. These problems must be considered in the design and operation of oil products pipeline. An analysis on the mechanism of temperature increment of oil products has been made,the equations for the temperature increment of oil products have also been given respectively. The calculated results show a good approach to measured results on the basis of a oil products pipeline case.
