The main advantages of pipeline transportation can be summarized as follows:
(1) Large volume.
Oil pipelines can continue to complete delivery tasks. According to the size of its diameter, its annual traffic volume can reach several million tons to 10 million tons, even more than 100 million tons.
(2) Small footprints.
Transportation pipelines are usually buried underground, occupying very little land; the construction of the transportation system indicates that 95% of the total length of the pipeline is buried above the pipeline, so the permanent occupancy of the land is very small, 3% of the road, about 10% of the railway In transportation planning systems, giving priority to pipeline transportation plans is of great significance for saving land resources.
(3) The pipeline construction period is short and the cost is low.
A large number of domestic and international transport system construction practices have proved that the construction period of the pipeline transportation system is generally shorter than 1/3 of the total railway construction volume in the same period. Historically, China's Daqing-Qinhuangdao 1152-kilometre-long oil pipeline was constructed for only 23 months, and a railway was built at the same flow rate, at least three years, Xinjiang to Shanghai, a total of 4,200 kilometers long natural gas pipeline, and construction is expected. The period does not exceed 2 years, but if the new railway lines are of the same quantity, and the construction period is more than 3 years, especially under the relatively harsh conditions of geological and climatic conditions, large-scale railway construction will be more difficult and the cycle will be longer. Statistics It shows that the cost of pipeline construction is about 60% lower than that of the railway.
(4) Pipeline transportation is safe, reliable and continuous.
As oil and natural gas are flammable, explosive, volatile, leaky and used for pipeline transportation, they are both safe and can greatly reduce volatilization losses, and due to air leakage, water and soil pollution can be greatly reduced, that is, pipeline transportation energy can To better meet the green needs of transportation engineering, in addition, because the pipeline is buried underground, the impact of the harsh and volatile weather conditions during the transportation process is small, which can ensure the long-term stable operation of the transportation system.
(5) Pipeline transportation has low energy consumption, low cost and good efficiency.
Developed countries use pipelines to transport oil. The energy consumption per kilometer of railways is less than 1/7 ton. Under the condition of relatively large transport costs and waterway transportation, pipeline transportation is one of the most energy-saving modes of transportation under water-free conditions. Theoretical analysis and practical experience show that the larger the pipe diameter and the longer the transportation distance, the greater the transportation volume, the higher the transportation cost, the higher the transportation cost and the higher the transportation cost. Low, taking transportation oil as an example, the ratio of transportation costs for pipeline transportation, water transportation, and rail transportation is 1:1:1.7.
