What is the inside diameter listed for a 10-inch insulation pipe covering?

• A. 10 3/4 Inch
• B. 10 1/2 Inch
• C. 9 3/4 Inch
• D. 11 Inch

Answer: (A)

Inside diameter is the space inside the insulation sleeve, sized to slip around the pipe with a little clearance for the insulation material and installation. For a 10-inch nominal pipe, the bore is typically a bit larger than 10 inches to allow easy placement and to accommodate the insulation layer. The common value you’ll see is 10 3/4 inches, which provides that necessary clearance without being so loose that it won’t seal properly. The other options would be too tight or too loose for a standard 10-inch setup, making 10 3/4 inches the best fit.
