Why is chilled-water piping insulated?
Correct Answer
B) Limit heat gain and condensation on the pipe surface
Chilled-water insulation limits heat gain and condensation; it does not support piping or replace tests.
Why This Is the Correct Answer
Chilled-water insulation limits heat gain and condensation; it does not support piping or replace tests.
Why the Other Options Are Wrong
Option A: The MEP foreman should increase drain slope
Choice A (Increase drain slope) is rejected because it answers the Pipe insulation purpose prompt with the wrong practical move.
Option C: The MEP foreman should replace pressure testing
The trap in C is Replace pressure testing. That selection is wrong because it removes the controlling Pipe insulation purpose requirement instead of meeting it.
Option D: The MEP foreman should provide structural support
Choice D gives Provide structural support. Its specific error: the option does not produce the required Pipe insulation purpose outcome, Limit heat gain and condensation on the pipe surface.
Memory Technique
Picture pipe insulation purpose doing the job; the answer names that job as Limit heat gain and condensation on the pipe surface.
Reference Hint
