Help, please! Does anyone know the three dimensions of a DN65 raised-face flange? Please help Brother Pig out. . Thank you! See figure: A = B = C=
A=118mm sealing surface diameter B=6mm projected length of the convex slope C=2mm height of the convex surface
A=122 mm sealing surface diameter B=122+2*C mm C=2 mm bulge height
I need to know the pressure rating of this flange in order to tell you accurately! Finally, please tell me the type of flange connection method, such as butt welding? Socket welding? Flat welding? (This may not be very useful.) It would be better if there were flange standards (this is extremely useful!) ! !
Is it national standard, European standard, or American standard? What is the pressure rating?
What about the pressure rating? What about the execution standards? Plate butt welding?
1. National standard: flange with an outer diameter of 185 mm, weld-free; suitable for pressures up to 10 MPa. . . . . 2. Are the three sizes of ABC related to the level of pressure?
d corresponds to your A, and f1 corresponds to your C value; these are the flange sealing surface dimensions per HG20592-2009, and they are related to pressure
It really is related to stress! ! ! It can also be said that the greater the pressure, the larger the size!
Pigs~ – in addition to stress, there’s also temperature; don’t mess around with that.
. . . . . . Now that you mention it, I’m finally clear-headed~~~ Yesterday it really confused me; I searched for \"flange dimensions\" but spent the whole afternoon without being able to figure out what the outer diameter was.
