Boiler Safety Valve Discharge piping - Safety Relief Valve

If this boiler was in an ASME jurisdiction, then you wouldn't be allowed to install a muffler (ref: ASME Sec I, PG-71.4). Be aware that the rules for steam boilers are different from those for pressure vessels - that's true in EU countries and in ASME jurisdictions. For example, the pressure drop rules don't apply to steam boiler applications.
