Flanged Flat Head
Flanged Flat Head
(OP)
Is there any flange flat head for a vessel? Where can I find reference to it? In ASME, is UG-34(11) Sketch(p), is that refers to flange type flat head?

RE: Flanged Flat Head
The head manufacturers make flanged flat heads which are a flat plate with a lip ("flange") that forms a short cylinder. These are normally made in thinner plate, and used for atmospheric applications. If used for any substantial pressure, the thickness becomes excessive, and it isn't feasible to form the lip/flange on it.
Not to be confused with a blind flange, which is addressed in the code, and commonly used as needed.
RE: Flanged Flat Head
Sketches (a) thru (d) would likely be considered flanged, flat heads, usually referred to as flanged-only heads. Sketches (j), (k) & (p) would usually be referred to as blind flanges. The rest are something else.

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

Yes you can. However you have to know that blind flange thickness is going to give you heavier ends. In case the vessel diameter gets large the dished end solution becomes more economical and operation and maintenance friendly.
For your application you need to consult a vessel design engineer to see the difference.

However, you need to consult a pressure equipment design engineer to determine the needs of your application.
