RTJ channel for ring gasket acc. to USAS B16.5/ 1968
RTJ channel for ring gasket acc. to USAS B16.5/ 1968
(OP)
Hello.
I am searching for the standard USAS B16.5/ 1968.
We have to prepare test blinds for some equipments which were made in 70's.
In these equipments, the nozzles appeared with the following notation: Flange SI DN80 PN63,3 according to USAS B16.5/ 1968.
The diameter of bolt circle is 170, it has 8 holes with 22mm diameter.
I think SI is the old notation for RTJ.
I want to know which is the RTJ channel dimensions for the ring gasket?
Thank you!

I've had a quick internet search and found a download, but it wouldn't download for me (possibly security issues) but if I was you I would write or call ANSI and ask how can you get a copy of US ASA B 16.5 1968.
Maybe you'll have better luck. http://ngbaationapplic.cf/asme-ansi-b16-5-1968
Does look a bit of a dodgy site alright....
Flanges used to be designated in metric and imperial at that time, but I agree with XL83NL, a PN 63.3 designation looks like it comes from a European standard, but may have been included somehow in B16.5 at that time.
