    Hi everybody, I have a question

    Hi. I got to say something, UG-10 does not apply to this type of issues. The ASME most likely will reject its use on code Works, it locks tests that cannot be done afterwards. My opinion only. General Blr. CA,USA

    per ASME Code, your air receiver does not need a fire rated safety r.valve but a pressure relief valve. consult your local fire chief and fire Codes to asses fire safety. If you want to instal an alternate safety for fire, you can probably use a Fuse Plug, the same that are used on Boilers...

    Electric boiler and explosion

    It's not to do with the pressure vessel but electrically. Explosion proof means you will use components suitable as NEMA 4X and choice of type and class as Div 1 class 1... Used where highly flammable gasses are present, gasoline, hydrogen General Blr. CA,USA
