About Pipelines

Pipeline Basics 

There are over 2.4 million miles of pipelines in the United States made up of liquid production, gather and transmission lines; natural gas production, gathering, storage and transmission lines; and gas distribution lines.  They are a critical part of our nation’s infrastructure.  In Tennessee alone, there are over 35,000 miles of these lines.  According to the National Transportation Safety Board statistics, pipelines are the safest form of transportation in the United States.

Transmission pipelines are made of steel, covered with a protective coating and buried underground where they quietly and efficiently deliver their products across the country.

Natural gas distribution lines are made of either steel or high-strength plastic and deliver the product to the end users.  They supply the resource we need to heat our homes and businesses, fuel factories and provide constant support to our way of life.

In the United States, we transport and use over 20 million barrels of liquid products every day and over 21 trillion cubic feet of natural gas every year.  To ensure that the products reach their destination safely, pipelines are tested and maintained through the use of cleaning devices, diagnostic tools and cathodic protection.  Cathodic protection provides rust-inhibitive activities through the pipeline system.
