What are the dimensions for restraint clamps for private fire service mains sized 4" to 6"?

The correct answer reflects the specified dimensions for restraint clamps that are necessary for ensuring the integrity and stability of private fire service mains. In the context of the installation for pipes sized between 4 inches and 6 inches, it is crucial that the clamps can provide adequate restraint to handle the forces associated with the operation and potential stresses on the pipeline. The dimensions of 1/2 inch by 2 inch are appropriate for this application, offering a effective balance of strength and compatibility with typical fittings and joints used in fire service installations.

Understanding the importance of these dimensions is essential for proper installation and long-term performance of the fire service mains. Restraint clamps must be specifically sized to fit securely around the pipes and provide the necessary resistance to movement and separation, especially in situations where water pressure can fluctuate or environmental conditions may place additional stress on the system. The chosen dimensions are compliant with NFPA standards and ensure that safety concerns are adequately addressed, contributing to a reliable fire protection infrastructure.
