Flange type

Hi experts;
please, what isthe differencies between hub flange and pad flange?

RE: Flange type

Hub is the the part of the WNRF with the taper.
A pad is of different construction, and often welded into something. Therefore it doesnt have a hub.

RE: Flange type

Hi Houari Yahiaoui,
You can find more information about pad flanges using the term Studded outlet flange.

The link XL83NL provided is amazing :p

RE: Flange type

Hub flange could also refer to a slip-on flange.

RE: Flange type

How about you post a drawing, sketch or picture of the two as "hub" and "pad" are not recognised terms in ASME B16.5 and so can mean different things to different people.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Flange type

See ASME VIII Div 1 figure UG-40 (a-1) and (a-2)as pad flange.
