摘要
煙景管線工程全長(zhǎng)440km，年設(shè)計(jì)最大輸量為500萬(wàn)噸，最小輸量為350萬(wàn)噸。
管線沿程地形較為起伏，最大高差為32m，經(jīng)校核全線無(wú)翻越點(diǎn)；在較大輸量時(shí)可熱力越站，較小輸量時(shí)可壓力越站。
輸油管采用瀝青加強(qiáng)級(jí)外保護(hù)的防腐措施。全線共設(shè)熱泵站12座，管線埋地鋪設(shè)。管材采用 406.4×7.9，L245的直弧電阻焊鋼管；采用加熱密閉式輸送流程，先爐后泵的工藝，充分利用設(shè)備，全線輸油主泵和給油泵均采用并聯(lián)方式。加熱爐采用直接加熱的方法。管線上設(shè)有壓力保護(hù)系統(tǒng)，出站處設(shè)有泄壓裝置，防止水擊等現(xiàn)象，壓力過(guò)大造成的危害。
首站流程包括收油、存儲(chǔ)、正輸、清管、站內(nèi)循環(huán)、來(lái)油計(jì)量及反輸?shù)裙δ?；中間站流程包括正輸、反輸、越站、收發(fā)清管球等功能。采用SCADA檢測(cè)系統(tǒng)，集中檢測(cè)、管理，提高操作的安全性和效率。
由計(jì)算分析證明該管線的運(yùn)行可收到良好的效益并有一定的抗風(fēng)險(xiǎn)能力。

ABSTRACT
The whole length of the pipeline is 440 kilometer and the terrain is plan.The maximum of transport capacity is 500 million ton per year and minimum of throughout is 350 million ton per year.
The choice of main equipment and determination of station site are based on the condition of every throughout. After the technical eva luation , one type of steel pipeline called L245 is select. The optimum diameter is 404.6 millimeter and the wall thicket is 7.9 millimeter.
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-to-pump tight line operation. Crude oil is heated at first and the pump in each station. There are three 220D-65×10pumps are equipped as the transporting pump. The process of flows in the station includes: collecting crude oil; forward transportation; reverse pumping over station and circulation in the station.
Along the main line, oil transportation included head station, intermediate heating and pumping station, and terminal station.
Through the benefit analysis and feasibility study of operation, the project has a good economic benefit and the design is feasible.

Keywords：pipeline corrosion；pump-to-pump station；analysis
