New Mexico Pipe Fitter Journeyman (JPF) Practice Exam

Mechanical tubes are designed to carry which of the following?

1. Fluids under pressure

2. Gases only

3. Solids

4. Air

The correct answer is: Fluids under pressure

Mechanical tubes are specifically engineered to carry fluids under pressure, which includes a variety of liquid substances such as water, oil, and other hydraulic fluids. The design of these tubes allows them to withstand not only the pressure of the moving fluids but also factors such as temperature fluctuations and potential chemical exposure depending on their application. While gases and air can also be transported in mechanical systems, they are generally categorized differently and might utilize specific types of tubing designed for gas flow. Solids, on the other hand, are not typically conveyed through mechanical tubes as they require different handling methods. Therefore, the focus of mechanical tubes is most accurately aligned with their primary function of transporting pressurized fluids.
