2. Sample Practice Question
Practice Question: In a high-pressure steam distribution main, what is the primary function of an eccentric reducer installed with the flat side on the bottom?
A) To maximize steam velocity through the reduction.
B) To prevent condensate accumulation and eliminate water hammer.
C) To facilitate pipe thermal expansion anchoring.
D) To equalize pressure between high and low pressure headers.
Correct Answer: B) Installing eccentric reducers flat-on-bottom (FOB) in horizontal steam lines prevents condensate pooling at the reduction point, preventing severe water hammer.
