What is the nominal pipe and fitting size recommended for use with an 18-inch pipe wrench?

• A. 1 inch to 2 inches
• B. 1 inch to 2.5 inches
• C. 2 inches to 3 inches
• D. 2.5 inches to 4 inches

Answer: (A)

The choice indicating a nominal pipe and fitting size of 1 inch to 2 inches for use with an 18-inch pipe wrench aligns with the general industry standards regarding wrench sizing and the types of pipes it is intended to be used with. An 18-inch pipe wrench is considered a large tool used primarily for gripping and turning larger diameter pipes. However, for general plumbing and pipefitting practices, the suggested range for smaller pipe sizes is typically 1 inch to 2 inches in diameter. This size range allows for efficient operation while maintaining the necessary leverage and control offered by a wrench of that size. For pipes larger than 2 inches, a larger wrench—often a 24-inch or even a 36-inch pipe wrench—would be more appropriate as it provides the leverage needed to turn heavier and larger pipe fittings safely and effectively.
