Pipeline transport is a mode of transportation that using steel pipe as a transport machine to transport liquid and gas materials in long distance, is a mode of transportation that transporting oil, coal and chemical products from the place of production to market, is a special component of trunk transportation in unified transport network. The cost of using pipeline to transport oil is high than that of water transport, but it is cheaper than railway transportation. Pipeline transport features to higher transportation capacity, continuous, rapid, economical, safe, reliable, smooth and less investment, less land occupied, low cost, and it can realize the automatic control. In addition to widely used in oil and natural gas long-distance transport, but also can be used in transporting ore, coal, building materials, chemicals and food.
The main pipe used in pipeline transportation is the steel pipe, in accordance with its manufacturing process can be divided into seamless steel pipe and welded steel pipe, and welded pipe can be divided into ERW steel pipe, LSAW steel pipe, spiral welded pipe, etc. According to different enviroment and diffferent application, we will select the steel pipe produced by different technology. Prime Steel Pipe are positioned as a steel pipe manufacturer and exporter for carbon steel pipe, stainless steel pipe, seamless steel pipe, welded steel pipe, steel pipe fittings, can provide all kinds of carbon steel pipe with different specifications and standards according to the requirements of customers.
The main advantages of pipeline transportation can be summarized as follows:
(1) Large capacity
An oil pipeline can continue to complete the delivery task. According to the difference of the size of the pipe diameter, its annual transport capacity can reach to several million tons or tens of millions of tons, or even more than 100 million tons.
(2) Less land occupation
Transport pipeline was usually buried in the ground, its land occupation is very small; the construction practice of transport system proved that the part of transport pipeline buried in the underground took up more than 95% of total length of the pipeline. So the permanent land occupation is very small, respectively amounts to 3% of the road and about 10% of the railway.
(3) Short construction period and low cost
A lot of practice has proved that, compared to the same traffic volume of the railway construction period, in general,the construction cycle of pipeline transportation system is shorter than 1/3.
(4) Safe and reliable, strong continuity
As the oil and gas is flammable, explosive, volatile and easy to leak, using pipeline transport is safe, and can greatly reduce the volatile loss, and the pollution caused by the leakage of air, water and soil can be greatly reduced.
(5) Little energy consumption, low cost and good efficiency
Pipeline transportation is a continuous project, the transport system does not exist no-load travel, thus the transport efficiency of system is high. Theoretical analysis and practical experience has proved the larger the diameter of the pipeline is, the farther the shipment distance is, the larger the traffic capacity is, the lower the transportation cost is. Using oil transport as an example, the transport costs ratio of pipeline transportation, water transport, rail transport is 1: 1: 1.7.
