B16.5 Flanges
B16.5 Flanges
(OP)
I'm in instrumentation and have a question with regard to flanges to B16.5 standards. If a vendor is supplying an inline magnetic flowmeter with CL 150 flanges to B16.5, can I assume that the flanges supplied are raised face (and not flat faced) ?
The instrument data sheets sent to him asks for CL 150 RF flanges. I've researched the internet and everything related to B16.5 refers to RF flanges but, it also says that you can in fact, get flat faced B16.5 flanges but, it looks like they originally started life as RF and had the facing machined off. (I did also notice that B16.5 covers 'lap joint' flanges which look flat faced.)
Many thanks.

If in doubt, ask the vendor.

I did receive good advice telling me that my assumption was incorrect and there was reasoning attached with the answers.
I was looking for a little bit more than just yes/no answer from the vendor.
Thanks thanks for the replies.

thanks for the reply. The vendor's quote came back with 'CL 150 flanges per B16.5' but there was no mention of RF so, I knew clarification was needed from him. It was the fact however, that he quoted B16.5 that got me thinking that this spec could be for raised face flanges only. Hence the reason for asking.
Regards.
