Safety valves over 3 inches should be attached to the boiler using either flanged connections or welded connections. This approach accommodates the larger size and ensures a secure and leak-free attachment to the boiler, which is vital for maintaining safety under high pressure.

Flanged connections allow for ease of maintenance, as valves can be removed and replaced without needing to cut or weld them, facilitating inspections or repairs. Welding, on the other hand, offers a permanent and strong bond, which can be advantageous in situations where the valve is unlikely to need removal or where space constraints do not allow for flanged connections.

Overall, the flexibility of being able to use either flanged or welded connections ensures that the safety valve is appropriately secured, able to withstand system pressures, and adheres to engineering codes and standards. This dual methodology enhances both the operational reliability and safety of the boiler system.
