Selection of flanges for tower equipment
Thread Content
There is now a atmospheric pressure tower. Diameter 1800, total height 15 meters. There are 3 equipment flanges, and the thickness of the equipment is 6 mm. I would like to use type A equipment flanges with a pressure rating of 0.25 MPa. However, upon calculation, it turns out that the required thickness for such flanges is too great, as the effective thickness at the narrow end of the neck is taken as the 6 mm thickness of the cylinder; calculations show that a thickness of over 80 mm is needed. I would like to ask whether, when selecting equipment flanges for tower equipment according to standards, calculations are necessary Do I still have to thicken the cylinder until I can perform the calculations?
The flanges on the tower equipment need to be calculated; they are subject not only to pressure loads but also to other types of loads. SW6 needs to include these flanges in the calculations, and it is necessary to provide the height position of the equipment flanges
According to the NB/T47041 standard, when calculating the container flanges of tower equipment, internal pressure, axial force, and external torque must be taken into account.
1. It is possible to thicken a certain part of the cylinder body, not the entire area. 2. The choice of gasket for the flange is very important; non-metallic gaskets should be used
The diameter of the equipment isn’t too small; should we consider using a manhole instead of the equipment flange?
