Pipeline (also known as pipeline, piping) is composed by a pipe and its annex, and in accordance with the needs of the process, with the corresponding pump unit, designed to be installed as a complete piping system to complete the fuel unloading and transport revolution task.

Pipeline system, which is used to transport oil and petroleum products pipeline system, mainly by pipeline, oil and other auxiliary station related equipment, is one of the main oil storage and transportation equipment industry, as well as crude oil and petroleum products main transportation equipment, compared with the same mode of transport on land belonging to the rail and road oil, oil pipeline has large volume, tightness, low cost and high safety factor.
Pipeline steel pipe generally using welding and flange connection means growing distance pipelines, and use of the valve opening and closing control and flow regulation. There are isothermal pipeline transportation, heating and other transportation and delivery order delivery processes. Pipeline corrosion and corrosion protection is an important part of how the pipeline conservation. Currently pipeline has become the main tool for transporting oil, and in the future still has considerable development potential.
