Pipeline transportation is a long-distance transportation method that uses pipelines as a means of transportation for liquids and gases. It is a special mode of transportation for transporting petroleum, coal, and chemical products from their production areas to the market, and is a special component of mainline transportation in the unified transportation network.

Sometimes, pneumatic pipelines can also perform similar tasks, compressing gas for transporting solid cargo tanks filled with goods. Pipeline transportation of petroleum products is more expensive than water transportation, but 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, requires less investment, occupies less land, and has low cost, but also can achieve automatic control. Pipeline transportation can save the transit trouble of waterway or land transportation, shorten the transportation cycle, reduce transportation costs, and improve transportation efficiency.

The current development trend of pipeline transportation is that the diameter of pipelines continues to increase, greatly improving transportation capacity; The distance of pipeline transportation is rapidly increasing; The transportation of substances has gradually expanded from fluids such as oil, natural gas, and chemical products to non fluids such as coal and ore.

From the perspective of advantages, pipeline transportation has its unique advantages in oil and gas transportation. Firstly, its transportation is smooth and uninterrupted. Modern large-scale production, continuous production in oil fields, continuous transportation through pipelines, and continuous production of finished products in refining and chemical industries to meet the needs of the national economy; Secondly, it has achieved safe transportation. For oil and gas, transportation by car and train is very dangerous, while pipelines are sealed underground, making them extremely safe; Thirdly, the quality is guaranteed, the pipeline is sealed for transportation, the oil does not evaporate, and the quality is not affected; The fourth is economy, with low pipeline transportation losses, low freight costs, less land occupation, and less pollution.
