After the technical evaluation , one type of steel pipeline called L245 is select. The optimum diameter is millimeter and the wall thicket is millimeter. In order to reduce the loss of heat, the pipeline is buried under the ground. The pipeline is coated with 7millimeter thick anticorrosion asphalt layer and impressed current catholic protection to protect the pipe from corrosion.The process of transportation is pumptopump tight line operation. Crude oil is heated at first and the pump in each station. There are three 220D6510pumps 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.
