What is the purpose of pipe insulation?

• A. To reduce heat transfer and energy loss
• B. To increase pipe diameter
• C. To prevent corrosion
• D. To support weight

Answer: (A)

Pipe insulation reduces heat transfer between the pipe and its surroundings, so hot water stays hot and cold water stays cold, which minimizes energy loss and lowers energy costs. It also cuts down on condensation on cold pipes, helping prevent moisture problems and protecting against freezing in exposed sections. It isn’t meant to change the pipe diameter, prevent corrosion, or provide structural support.
