How thick should restraint straps for tees be for 4", 6", 8", and 10" pipes?

Restraint straps for tees in the context of the NFPA 24 standard are crucial for ensuring that piping systems remain secure and capable of withstanding the forces exerted on them during operation, particularly under conditions such as water hammer or seismic events. According to the NFPA 24 guidelines, the specified thickness of restraint straps is critical to provide the necessary strength and durability.

For 4", 6", 8", and 10" pipes, a thickness of 5/8 inches is deemed appropriate. This thickness strikes a balance between being robust enough to bear the imposed loads and preventing excessive weight which could complicate installation or lead to additional costs.

The selection of this specific thickness also aligns with industry standards and practices to ensure compatibility with pipe materials and connected fixtures, enabling efficient modern fire protection systems to function as intended without the risk of failure due to insufficient restraint. Choosing 5/8 inches ensures that the restraints are effective but not over-engineered for the purpose they are meant to serve.
