ASME Code Standards For Pressure Vessels And Piping Engineering Practice Test

Pipe supports primarily prevent which of the following in a piping system?

Corrosion Thermal expansion Vibration Excessive stress and displacement

Correct Answer:

Excessive stress and displacement

Explanation:

The main idea is that pipe supports are there to carry the pipe’s weight and control how it can move, so deflections and bending stay within what the design allows. By providing fixed points and guided paths, they resist gravity and the loads from the contents, keeping stresses in the pipe and its connections at safe levels. When the pipe heats up and expands or cools and contracts, the supports constrain that movement enough to prevent excessive stress and displacement, which is why preventing excessive stress and displacement is the primary function. Corrosion comes from material and environment, not from what supports do, and while support layout can influence vibration, the core purpose isn’t vibration control.
