RE: Non-Circular flange with Non-Circular Bore
So give us some dimensions.
RE: Non-Circular flange with Non-Circular Bore
Major axis I.D=450mm
Minor axis O.D=435mm
Minor axis I.D=350mm
Shape is like circular oblong.
Type of flange is somewhat similar to APP.2 fig 2-4-6a..Design pressure=6bar, Temp=200°C,M.O.C=SA181 Gr 60.
RE: Non-Circular flange with Non-Circular Bore
Now, that may be a problem on my end, but your description doesn't make sense.
It's low pressure, low temperature, so it can be fabricated fairly cheaply. Somehow.
Now. Draw it. Inlet and outlet nozzles - seem to be the two above based on OD and ID. Maybe.
Length, end-to-end?
Type of material for transition?
Bolt "circles" at end mating flanges? Bolt diameters and bolt hole diameters? nbr of bolts?
Flange surfaces? flange styles?
or is this a single flange, mated to its partner that is a combination of the two major OD and minor ID's above?

Thanks for your help.

Did you try UG-34?

My component is not flat head and cover its like STUB END, which is fastened with C-Clamp to cover(which i can design as per UG-34) and it has oblong shape because on matching cover its has two 150 and 80 Dia. glass.
