Monoflange according to asme b16.34 2

No. Are you mad?

You do know what a monoflange is??

E.g.

Also: If you get a response it's polite to respond to it.

I am confused because i see some Monoflange manufacturers saying that the monoflange has been designed according to asme b16.34

The internals might correspond to B16.34, but this is not a flanged end valve to 16.34....

Thank you very much for your explaining!

Please refer to paragraph 6.7 in ASME B16.34 for wafer or flangeless valves. Your monoflange valve appears to be this type of valve and if it complies with the requirements of paragraph 6.7, then it is within the scope of B16.34.

This is very important information for me. Thank you very much .

Could you please help me with this issue?

Paragraph 6.7 shows that a flangeless valve shall conform to the applicable requirements for flanged valves and the requirements of Paragraph 6.7.

I don't see a specific paragraph about flanged valves, only paragraph 6.2.2 Flanged Ends. The requirements in 6.2.2 contain only information about the flange and not about the valve itself.

My questions:
1. Must a flangeless valve meet the requirements of paragraph 6.2.2 Flanged Ends? or
2. Did they mean with “requirements for flanged valves” the general requirements throughout the standard?

Thank you very much for your time.

You have the right paragraph for flanged valves. It is 6.2.2. It says, "Flanged ends shall be prepared with flange facing, nut-bearing surfaces, outside diameter, thickness, and drilling in accordance with ASME B16.5..."

Flange facing is applicable
nut-bearing surface is not applicable
outside diameter is not applicable
thickness is not applicable
drilling is applicable, but also meets the additional notes in paragraph 6.7.

I don’t know how to thank you. You helped me so much

You’re the best!
