1、 *原油管道初步设计 学生姓名:* 学 号:* 专业班级:油气储运工程 *班 指导教师: 2006 年 6 月 18 日 摘要 *管线工程全长 865km, 年设计最大输量为 506 万吨, 最小输量为 303.6 万吨,生产期 14 年。 管线沿程地形较为起伏,最大高差为 346.8m,经校核全线无翻越点; 在较大输量时可热力越站,较小输量时可压力越站。 输油管采用沥青加强级外保护的防腐措施。全线共设热泵站 12 座,管 线埋地铺设。管材采用406.48.0,X65 的直弧电阻焊钢管;采用加热密 闭式输送流程,先炉后泵的工艺,充分利用设备,全线输油主泵和给油泵均 采用并联方式。加热炉采用直接
2、加热的方法。管线上设有压力保护系统,出 站处设有泄压装置,防止水击等现象,压力过大造成的危害。 首站流程包括收油、存储、正输、清管、站内循环、来油计量及反输等 功能;中间站流程包括正输、反输、越站、收发清管球等功能。采用 SCADA 检测系统,集中检测、管理,提高操作的安全性和效率。 由计算分析证明该管线的运行可收到良好的效益并有一定的抗风险能 力。 关键词关键词: : 管型;输量;热泵站;工艺流程 ABSTRACT The design of * pipeline engineering for oil transportation is complete on June 2006.The
3、whole length of the pipeline is 865 kilometer and the terrain is plan. The maximum of transport capacity is 506 million ton per year and minimum of throughout is 303.6 million ton per year. The choice of main equipment and determination of station site are based on the condition of every throughout.
4、 After the technical evaluation , one type of steel pipeline called X65 is select. The optimum diameter is 404.6 millimeter and the wall thicket is 8.0 millimeter. The maximum pressure of operating for design is 450MP. In order to reduce the loss of heat, the pipeline is buried under the ground. The pipeline is coated with 7-millimeter thick anti-corrosion asphalt layer and impressed current catholic protection to protect the pipe from corrosion. The process of transportation is pump-
