New Mexico Pipe Fitter Journeyman (JPF) Practice Exam

What is the end to center measurement of a long radius return bend compared to the nominal pipe size?

1. 1 x NPS

2. 2 x NPS

3. 3 x NPS

4. 4 x NPS

The correct answer is: 3 x NPS

The end to center measurement of a long radius return bend is determined based on the nominal pipe size (NPS). For a long radius bend, the end to center distance is typically three times the nominal pipe size. This means that if the nominal pipe size is specified, the length from the end of the bend to the centerline of the pipe is calculated as three times that size. This standard helps ensure proper fit and alignment in piping systems, allowing for adequate space for connections and sufficient flow characteristics. In contrast, different types of bends or fittings, like short radius bends, may have different measurement standards, impacting how they fit into a system. Understanding the correct measurement for long radius bends is essential for accurate pipe fitting and compliance with industry standards.
