The pipeline is 265km long,6.2to 109m high. the section which pipeline passed is smooth，The designed capacity of transportation is 17 million tons per year. The tight line operation is used in all line, called “from pump to pump”. On the basis of criteria, 1.8 meters per second is choosen. At last, Φ720×8, L480（X70）pipe is used. 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 operation arrangement of different flow rate are illustrated. In order to adapt to the flow rate necessary of different terms, changing the temperature of the heater, controlling the amounts of the pump, or non-pumping and heating operation are promised. The last , analysis of the projects economic becefics is necessary. Keywords: flow rate; technological process; heating and pumping station; operation arrangement 目 录 TOC \o 1-2 \h \z \t 22222222222222222222,2 HYPERLINK \l _Toc138175209 第1章 前 言 1 HYPERLINK \l _Toc138175210 1.1输油管道组成 PAGEREF _Toc138175210 \h 错误！未定义书签。 HYPERLINK \l _Toc138175211 1.2我国输油管现状 PAGEREF _Toc138175211 \h 错误！未定义书签。 HYPERLINK \l _Toc138175213 第2章 设计说明书 PAGEREF _Toc138175213 \h 9 HYPERLINK \l _Toc138175214 2.1 工程设
