Distance between RD and PSV

[shiplu48]

Hello,



Is there any regulations regarding the distance of rupture disc installation with PRV?

One information that I have found is "it should be closed coupled (1-2 feet)". But I don't know where does it come from, ASME or API?

According to this rule distance between PRV and RD should be greater than 2 feet.



Any recommendation is highly appreciated.



Many Thanks.

I recommend reading studying section 4.3, titled Rupture Disk Devices, in API 520 Part I. If you have further questions after that, come back.

Good luck,
