Interstate Pipeline

Definition - What does Interstate Pipeline mean?

An Interstate Pipeline is a large diameter steel pipeline that is used to transport crude oil, natural gas and petroleum products within neighboring countries. These pipelines are also known as cross country pipelines since they cross borders. They are spread strategically across countries through which country specific intrastate pipelines are connected. These intrastate pipelines are further spread strategically as a grid network for carrying various hydrocarbons as per the requirements of different states within the country.

Petropedia explains Interstate Pipeline

Pipelines are one of the safest and most effective ways of transporting crude oil, natural gas and petroleum products between border sharing nations and states. The industry jargon for pipelines varies with respect to the oil and gas sectors, i.e., upstream, midstream and downstream sectors.

In the upstream sector, pipelines which carry crude oil and natural gas from the wellhead to the processing plants are called gathering systems. These are small diameter pipelines. Once crude oil and natural gas are processed and impurities are removed, they are sent to trade in the market of the countries or states which need them via trunk pipelines (intrastate as well as interstate pipelines). The crude oil is transported to the respective countries or the state refineries for further processing via large diameter trunk pipelines. Once the Petroleum products are produced, they are further transported to various demand centers within the country either by intrastate pipelines, rail or road network. To carry the products further to the customers, small diameter pipelines called spur lines are connected to these large diameter mainlines which carry the products further to the densely populated demographic regions. Interstate pipelines have diameters which range from 20 inches to 48 inches or more.
