New Mexico Pipe Fitter Journeyman (JPF) Practice Exam

When tacking a flange to a pipe or fitting, which three factors must be considered?

1. Gap, high-low, and level of holes

2. Gap, spacing, and alignment

3. Height, width, and pressure

4. Spacing, tension, and level of holes

The correct answer is: Gap, high-low, and level of holes

When tacking a flange to a pipe or fitting, it's crucial to consider the gap, high-low, and level of holes to ensure a proper fit and seal. The gap refers to the distance between the flange and the pipe or fitting, which needs to be consistent to avoid stress concentration and ensure a uniform sealing surface. High-low pertains to the alignment of the flange in relation to the pipe or fitting. If one side is higher than the other, it can lead to improper sealing and potential leaks once the system is in operation. Achieving a proper high-low alignment ensures that the flange sits flat against the connecting surface. The level of holes is important for ensuring that the bolt holes on the flange line up correctly with the corresponding holes on the pipe or fitting. Misalignment can lead to difficulties in securing the flange and could compromise the connection integrity. Taking these three factors into account allows for a secure and efficient tacking process, which is essential for the overall success of the installation.
