Both in Dagang and Huabei oilfields, which are located in the northern China, sales pipeline have been laid. For the refinery enterprises located in the northern China, including Dongfanghong(located in Yanshan, Beijing), Dagang, Tianjin, Changzhou, Shijiazhuang, Baoding and Huhehaote ( located in the Inner Mongolia)refineries, the total oil pipeline length reaches 1847.4km.

Qin-Jing pipeline from Qinhuangdao to Beijing is a trunk pipeline constructed the earliest in north China to supply crude oil for Dongfanghong refinery. The construction of Qin-Jing pipeline begun in Apr.1974 and completed on Jun.19, 1975. It has a total length of 324.6 km with an annual delivery capacity of 600 ×104tons and passes through rivers at 11 places, railway at 14 places and roads at 40 places as well as crosses over streams(Yongdinghe 1574 m) and ditches at 5 places. Qin-Jing pipeline was designed by Luoyang Petrochemical Design Institute ( subordinate to Luoyang Petrochemical Engineering Company, SINOPEC) and constructed by the Third Pipeline Construction Company and Jianghan Pipeline Construction Company.

The oil pipeline from Dagang to Zhoulizhuang was constructed in 1968, which is the only sales pipeline in Dagang oilfield. Although its start point changed many times, it has a total length of 210.5 km and an annual transport capacity of 500 ×104 tons.

The pipeline from Renqiu to Changzhou was constructed in Jan.1976 and put into operation on the first day of Apir.1976. It has a total length of 210.5 km and an annual delivery capacity of 500 ×104 tons, which has been increased to 770 ×104 tons after revamped in 1983. The pipelines originated from Huabei oilfield includes also Ren-Chang dual pipeline, new Ren-Chang pipeline, Ren-Jing pipeline(from Renqiu to Beijing),Chang-Lin pipeline(Changzhou to Linyi), He-Shi pipeline(Hejian to Shijiazhuang), Ren-Bao pipeline(Renqiu to Baoding) and Ar-Sai pipeline(Arshan to Saihantala).

The oilfields in the central China such as Jianghan, Henan and Zhongyuan oilfields, are located in Hubei and Henan provinces, where the major refinery enterprises include Jinmen(in Hubei province) and Luoyang(in Henan province) refineries. The total length of pipelines is 1347.5 km.

Qian-Jin pipeline (Qianjiang to Jinmen) originated from Jianghan oilfield with a length 90 km was completed in 1970 and has an annual delivery capacity of 170 ×104 tons.
Pipelines in Henan oilfield are Wei-Jin(Wegang to Jinmen) pipeline and Wei-Jin dual pipeline.

Pipelines originated from Zhongyuan oilfield are Pu-Lin(Puyang to Linyi) pipeline, Zhong-Luo pipeline(Puyang to Luoyang) and Zhong-Luo deplex pipeline.

Moreover, the total pipeline length from the port to the refinery is 859.3km.
