ASME Line Blanks above 24"
ASME Line Blanks above 24"
(OP)
I have a 30" Flare line that requires spade/spacer out of the K.O. Drum but B16.48 ends at 24".
What code can I use for 30" / 36" ?
What code can I use for 30" / 36" ?

I realize it's not the same thing as a line blind but if you only need to seal off from one direction might be a starting point.
Or section 304.5.3 in B 31.3 gives you a calculation to use.

You would not need the same thickness for a line blind as you need for a Blind Flange!!!
RE: ASME Line Blanks above 24"
Give me some credit - I know that and said so in my response.
The OP was asking for codes to use - one option if all you want to do is seal from one direction is to use a blind flange to ASME B 16.47
If he wants to use a line blind / spade then he can calculate it as per B 31.3 section noted above.

Touched a sore spot there. The OP was asking about line blanks (spade/spacer) not blind flanges so blind flange option should not have been brought into the discussion.
RE: ASME Line Blanks above 24"
Not a sore point and maybe not, but it's the only "code" I could find for > 24" so if the OP wanted an easy way out it is an option, but maybe one he doesn't want to pursue.
Maybe you can use a blind flange, but get a sealing surface machined on both sides?
