Different Types of Pipelines
Pipelines are divided up into different categories depending on what they carry, and where they go. Understanding these categories is important because they determine how pipelines are constructed and regulated.

Hazardous Liquid Pipelines carry fuels like gasoline, diesel, jet fuel, etc.

Gas Pipelines carry natural gas and propane.

Transmission Pipelines are the larger lines that move gas and liquids around the country

Distribution Pipelines are the smaller lines that move mainly gas within communities and to our individual homes and businesses.

Interstate Pipelines are lines that cross state or national boundaries

Intrastate Pipelines are lines that do not cross state boundaries.
