Calculation of Spade Thickness
Calculation of Spade Thickness
(OP)
Gentleman,
I want to calculate the min required thickness of carbon steel spade to insert between flanges for shutdown isolation work.
Flange size is 4" #600, natural gas pressure is 70 barg. Can someone advise please.
Thank you very much.

Thank a million.
Everybody please share whether in your engineering/standard practice. On shutdown turnaround, in case entry of static equipments, should we install temporary spade/blind that the thickness comply to ASME B31.3 para 304.5.3 if we have blocked typical block valve already.
Is thin blind be acceptable in your standard practice?
