I live in Canada and my query is with regards to Double block and bleed valve. My understanding is that a professional engineer can sign off on a smaller bleed line size for Double Block & Bleed applications or requirements, however this has been challenged that this only relates to confined space entry applications.
I want to know if there is a limitation to the bleed line size based on the purpose of Double Block & Bleed valves/devices? What I would like to identify is this, are there limitations to a professional engineer on signing off a variance for a Double Block & Bleed devices.
