Allowances may be made for the expansion and contraction in piping by the use of expansion joints or __________.

Correct Answer: Option C — bends or loops in the line

Piping systems must account for thermal expansion to prevent stress-induced failures. Bends, loops, or expansion joints provide the necessary flexibility to absorb movement without damaging flanges or supports. 46 CFR requirements for piping systems emphasize the importance of managing thermal stress to maintain structural integrity in high-pressure lines.
