Pipeline in logistics transportaion bears almost all gases and most fluid transport of goods. Different transport object, which can be divided into the pipeline transportation of natural gas pipelines and solid slurry pipeline transportation of three.

1. Pipeline Transportation

Pipelines are generally used for long-distance transportation of crude oil or refined oil products, which mainly consists of two parts, consisting of oil stations and pipelines, connecting the oil fields, refineries, oil depots or other oil pipeline units.

With the development of economy and society, the demand for natural gas will continue to increase.
