Can we use SORF plate flanges as per B16.5 but without hub ????

[Mozy91]

Is there any provision given from SORF plate flanges without hub as per B16.5, as i see reducing flanges and bling flanges can be made from plate without hub.

But mostly all vendor provide the SORF plate flanges as per B16.5.

Plz clarify ...

No. The "blind flange" is NOT a slip-on flange. It is the "cover plate" that is bolted onto the slip-on flange (raised face or flat-face) to block the end of the pipe. A "reducing flange" is what I think you are calling a blind flange with a hole in it for a reduced diameter instrument or smaller pipe.

Sir,
Thanks for your reply,
but Plz see attach as per b16.5 note b,

Plate can be used for blind and reduced flanges without hub,

My question is can reduce flanges and slip on flanges be same type as i seen many vendors provide plate flanges without hub for slip on flanges.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

I'm not sure I entirely understand your question. But will point out that flanges may be available that meet AWWA C207 or API-650, ASME B&PV Code, non-code applications, etc. IE, the fact that flanges exist and are commercially available doesn't mean they necessarily meet the specification you're working with.

JStephen, exaactly. You can buy B16.5 pattern flanges out of 410 SS, but they are not B16.5 flanges.

You can buy B16.5 pattern flanges out of PVC, but they are not B16.5 flanges...

In B16.5 standard flange , dimensions are provided with hub details for slip on flange,
But my question is if i used SA 516 PLATE and make a flange as per B16.5 standard then whether should i keep hub on flange or remove it ,

\Hope u got my question ......

 

[SnTMan]

Yeah, got it, see Table 6, Note 1.
