Where should a bevel cap be used?

• A. On the bottom of the pipe
• B. On the side of the insulation
• C. At the termination of the top of the vertical pipe insulation
• D. At the midpoint of the pipe

Answer: (C)

Bevel caps are used to finish the exposed end of insulation on a vertical pipe. When the insulation ends at the top of a vertical run, the cut end sticks out and is vulnerable to moisture and air infiltration. A bevel cap fits over that cut end, creating a beveled edge that sheds water and seals the termination. This provides a neat, weather-resistant finish right where the insulation ends on the top of the vertical pipe. It wouldn’t make sense to use it at the bottom, along the side, or at a midpoint where there isn’t an exposed end to cap.
