What equipment hazard can result from the improper operation of alignment?
A) Metal stress from thermal shock
B) Overheating, tube fouling, or melting
C) Possible damage if the safety valve is not working properly
D) Overpressurizing the heat exchanger
Answer: B
Explanation: A) Incorrect. Metal stress from thermal shock can be caused by applying heat to the exchanger without following the proper warm-up procedure.
B) Correct. Overheating, tube fouling, or melting can be caused by misalignment.
C) Incorrect. Possible damage if the safety valve is not working properly can be caused by operating a heat exchanger with ruptured tubes.
