Pipeline transportation is a long-distance transportation mode of liquid and gas substances using pipeline as a means of transportation. It is a special mode of transportation that transports petroleum, coal and chemical products from the place of origin to the market, and it is a special component of trunk transportation in the unified transportation network.

Sometimes, pneumatic pipes can do similar work, and compressed gas is used to transport solid tanks filled with goods. Pipeline transportation of petroleum products is more expensive than water transportation, but it is still cheaper than railway transportation. Most pipelines are used by their owners to transport their own products.

Pipeline transportation is not only large-scale, safe, reliable, stable, continuous, fast, economical, less investment, less land occupation and low cost, but also can realize automatic control. Pipeline transportation can save the transit trouble of waterway or land transportation, shorten the transportation cycle, reduce the transportation cost and improve the transportation efficiency.

At present, the development trend of pipeline transportation is: the diameter of pipeline is constantly increasing, and the transportation capacity is greatly improved; The pipeline transportation distance increases rapidly; Material transportation has gradually expanded from fluid such as oil, natural gas and chemical products to non-fluid such as coal and ore.

From the advantage point of view, pipeline transportation has its unique advantages in oil and gas transportation. First of all, its traffic is smooth and uninterrupted. Modern production, continuous production in oil fields, continuous pipeline transportation, and continuous production of finished products in oil refining and chemical industry meet the needs of the national economy; The second is to realize safe transportation. For oil and gas, the transportation of cars and trains is very dangerous, while the pipeline is sealed underground, so it is extremely safe; Third, the quality is guaranteed, the pipeline is sealed, the oil is not volatile, and the quality is not affected; Fourth, economy, low pipeline transportation loss, low freight, less land occupation and less pollution.
