Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
The US natural gas pipeline system is a complex system of pipelines that carries natural gas nationwide and for import and export for use by millions of people daily for their consumer and commercial needs. Across the country, there are more than 210 pipeline systems that total more than 305,000 miles of interstate and intrastate pipelines.
The pipeline was shut down in the U.S. by the Biden Administration. The U.S. portion of the Keystone Pipeline included 1,744 kilometres (1,084 mi) of new, 30-inch-diameter (760 mm) pipeline in North Dakota, South Dakota, Nebraska, Kansas, Missouri, and Illinois. [28] The pipeline has a minimum ground cover of 4 feet (1.2 m). [29]

Nominal Pipe Size is used for the outside diameter of pipes. Below NPS14, the NPS number is not consistent with the pipe diameter in inches. Copper tubing, however, is measured in nominal size, 1 ⁄ 8 inch less than the outside diameter. The Schedule system is used for standard pipe thicknesses.
