Witnessing the ten-year development of chemical processing equipment, we celebrate the prosperity and strength of modern China. This is just a preliminary contribution; we welcome everyone to participate more actively in discussions on this forum – the more people involved, the more lively it becomes. Haichuan becomes even better with you here. Replies are rewarded; feel free to discuss! ------------------------------------------------- On November 1, 2013, the trial operation of the Yangluo–Changsha branch line of the Lanzhou–Zhengzhou–Changsha refined oil pipeline project (referred to as the Lanzhou-Zhengzhou-Changsha refined oil pipeline) was successfully completed. Thus, the entire main line of the Lan-Zheng-Chang crude oil pipeline has been completed and put into operation. 　　The Lanzhou-Zhengzhou long-distance oil pipeline has a total length of 2,737.8 kilometers, of which the main line is 2,080 kilometers long and the branch lines are 657.8 kilometers long. The main route starts in Lanzhou City, Gansu Province, passes through 69 counties and cities in 5 provinces—Gansu, Shaanxi, Henan, Hubei, and Hunan—and ends in Changsha City, Hunan Province. The Lan-Zheng-Chang crude oil pipeline has a maximum annual transport capacity of 15 million tons, with a design pressure ranging from 8 MPa to 14 MPa. 　　In recent years, with the operation of the Central Asia Pipeline and the Western Pipeline, as well as the increased processing capacity of refining enterprises in the western region, a large volume of refined oil destined for external shipment has gathered in Lanzhou, increasing the pressure to transport it out. Coupled with the economic development in the Central Plains and Hubei-Hunan regions, a large amount of refined oil must be imported from various places each year to meet market demand. The completion and operation of the Lanzhou-Zhengzhou main pipeline for refined oil have resolved the issue of transporting refined oil out of Lanzhou, reduced transportation costs, and ensured the safe, stable, and efficient delivery of oil. It also holds great practical significance for accelerating the development of main pipelines for transporting oil from the north to the south and from the west to the east; by using these main pipelines to drive the growth of branch lines, it is possible to gradually expand into regional markets, ultimately creating a refined oil distribution network that is economically viable and flexible in terms of transportation. 　　As the longest and largest-diameter refined oil pipeline project built in China at one time, the Lan-Zheng-Chang refined oil pipeline is the first project constructed by CNPC under the separation of construction and operation system. It adopts an owner+EPC management model characterized by \"one-level management, two entities, three parties’ responsibilities, and four unifications\". 　　As of November 5, the Yangluo–Changsha terminal branch line had transported 150,000 cubic meters of diesel, of which 50,846 cubic meters were supplied to sales depots.
