Measuring the size of a pipe is a crucial step in various industrial and construction applications. It ensures that the correct pipe is selected for the intended purpose, avoiding costly errors and ensuring system efficiency.
To accurately measure the size of a pipe, two primary dimensions are considered: the nominal pipe size (NPS) and the outside diameter (OD). The NPS, often referred to as the “schedule number,” designates the pipe’s standard size and wall thickness. It is typically measured in inches and is crucial for determining the pipe’s flow capacity and pressure rating.
