设计题目： Z-L输油管道初步设计

摘要

本管线设计最大设计年输量为2000万吨。管道全长220km，所经地段地势较为平坦，高程在28～88m之间。经过计算，不存在翻越点。全线均采用“从泵到泵”的密闭输送方式以及先炉后泵流程。

本设计根据经济流速来确定管径，选为Φ813×10.3，管材选择无缝钢管，钢号Q345，最低屈服强度为325MPa。

经过热力和水力计算，确定了所需的热站和泵站数，考虑到运行管理的方便，热泵站的合一。

本设计中遵循在满足各种条件的情况下，工艺流程尽可能的简单，并且输油工艺本着应用先进技术的原则，进行了首站和中间站的工艺流程设计。

最后绘制五张图：管道纵断面图，中间热泵站工艺流程图，首站平面布置图，泵房安装图，首站工艺流程图。

ABSTRACT

The length of the pipeline design is 220 kilometers, the elevation height is between 28-88 meters,the section which pipeline passed is smooth.Go through the calculate, there was no get over point.This design used tight line pumping which called “from pump to pump”, so it can reduce consumptive waste, Moreover, this method can utilize sufficiently remain pressure head.

In the design, economic pipe diameter is firstly determined by economic velocity. At lest, Ф813×10.3,L325 pipe is used.

The transportation capacity and the geography conditions are considered of in order to determine the heating station. And including the environmental protection the worker's live conditions and so on. Finally, the heating station id placed to the first station,0Km. And direct heating is used.

In the condition of meeting all the kinds of those factors, the technological processes are used as simply as possible, and the advanced technologies are used an usually as possibly. In each station, oil is first heated and then pumped in heating—pump station in the design. The process of the origin station is: forward transportation, reverse transportation, heat oil cycling and pigging operation, etc. The technology process of the following station is: forward transportation, reverse transportation, non—pumping operation, non—heating oil cycling and pigging operation, etc.

The last , analysis of the projects economic becefics is necessary.The IRR is included.SO ,the project is possible.
