What is the end to center measurement of a 90 degree short radius elbow?

The end to center measurement of a 90-degree short radius elbow is defined as 1 times the Nominal Pipe Size (NPS). In piping systems, the term NPS is used to denote the size of the pipe, and short radius elbows are designed with a tighter bend than long radius elbows.

For a short radius elbow, the dimension is crucial for fitting into confined spaces or for systems that require a more compact design. This standard measurement helps ensure that the fitting will properly align with other installed piping, allowing for effective flow and maintenance of pressure within the system.

Understanding this measurement is important for pipe fitters as it influences installation and routing of piping in various applications, ensuring both efficiency and compliance with industry standards.
