Question

question 77 of 100 - multiple choice
pipe strain must be corrected?
a after alignment is complete
b pipe strain does not have to be corrected
c while performing alignment
d before starting alignment

Explanation:

Identify the core requirement of shaft alignment

Shaft alignment cannot be performed accurately if external forces, such as pipe strain, are acting on the machinery casings.

Determine the correct sequence of operations

Pipe strain must be measured and corrected before starting the actual shaft alignment process to prevent the piping from pulling or pushing the machinery out of its aligned position.

Answer:

• (A) after alignment is complete
• (B) pipe strain does not have to be corrected
• (C) while performing alignment
• (D) before starting alignment (Correct answer)
