1986年9月15日,我国第一条高凝油长输管线胜利投产了,这条管线的建成投产标志着辽河局的原油集输技术跨入了新领域。这条管线全长51.4km,起点是沈阳油田胜一转油站,终点是牛居油田牛一联合站,在首站和末站之间设一座中间加热站和阴极保护站。沈牛管线采用小φ219×6mm 日本工字焊直缝钢管,管线设计年输油能力85万 t,日输量2300t,最人工作压力6.4MPa,起点油温85℃,中间站加一次温,到末站的油温不低于56℃。该管线经过地区的地形、地貌比较复杂,有10km 沿着油田新铺的公路敷设,有25km 通过水田沼泽地,其余在旱田和荒地敷设;穿越
September 15, 1986, China’s first high-oil long-distance pipeline successfully put into operation, the completion of this pipeline put into operation marks the Liaohe Bureau of crude oil gathering technology into a new area. The pipeline is 51.4km in length with the starting point being the Shengli Oil Transfer Station of Shenyang Oilfield and the terminus of the Niuyi Union Station of Cattle Oilfield. An intermediate heating station and a cathodic protection station are set up between the first station and the last station. Shen Niu pipeline using small φ219 × 6mm Japan IWC straight pipe, pipeline design annual oil capacity of 850,000 t, the daily output of 2300t, the most working pressure 6.4MPa, the starting temperature of 85 ℃, the middle station plus a temperature, To the end of the oil temperature of not less than 56 ℃. The pipeline passes the terrain of the area with a complex topography. There are 10km of roads laid along the new oilfields, 25km through paddy fields and the rest laid on dry fields and wasteland.
