What is the width of restraint straps for 12" pipe?

• A. 2 in.
• B. 2 1/2 in.
• C. 3 in.
• D. 3 1/2 in.

Answer: (C)

The correct width of restraint straps for a 12-inch pipe, as specified in NFPA 24, is 3 inches. This measurement is vital for ensuring that the restraint system adequately secures the pipe during system operation, particularly when under pressure or during seismic events. The restraint straps must be wide enough to distribute the required forces over a larger surface area to prevent damage to both the pipe and the fittings, ensuring the integrity of the fire service main. By following these guidelines, the installation will conform to safety standards that help maintain functionality and reliability in a fire protection water supply system.
