当前世界上的石油运输多采用管道输送。那么管道是怎样运输石油呢?首先,从管道建设谈起。石油管道的建设要先进行线路的勘查,再进行管道的铺设,管道可埋在地面下,也可架设在地面以上,既可穿越山丘,又可跨越江河,还可穿越河底。在一条管线间每隔5O～300千米修建一座液压泵站,同时建设加热站和储油罐。为保护管线,在建管道所用钢管内外壁上涂抹防腐材料和保温绝缘材料。其次,要在原油进入管道输送前要进行清渣的准备输送工作。石油从油矿井开采出之后呈黑色液体,称为原油,在原油中除了由
Currently, petroleum transportation in the world mostly uses pipelines. So how do pipelines transport oil? First, talk about pipeline construction. The construction of oil pipelines must be preceded by the exploration of the pipeline and the laying of pipelines. The pipelines can be buried under the ground or above the ground. They can cross the hills, cross the rivers, and pass through the bottom of the river. A hydraulic pump station is built every 50 to 300 kilometers in a pipeline, and heating stations and storage tanks are built at the same time. In order to protect pipelines, anti-corrosion materials and thermal insulation materials are applied to the inner and outer walls of the steel pipes used in the construction of pipelines. Second, the preparation and transportation of slag should be carried out before the crude oil enters the pipeline. After oil is extracted from an oil well, it is a black liquid, called crude oil, except in crude oil.
