How should I understand the openings in flanged flanges?
Thread Content
A mixing tank, with a flange on the upper part of the head used to connect to the motor’s shaft; as a result, there is a hole in the head. How should this hole be calculated? Or should it not be taken into account? How should we understand this?
It’s the dissolution tank, right? Calculations are needed – the flange should be treated as a pipe connection, with openings added for reinforcement. It’s also necessary to calculate the stress on the flange, the shear force, as well as the stresses associated with mechanical rotation, and so on...
Reply to 2# SuperFree2316: Thank you for your help, but I still don’t understand. This flange is welded to the outside of the head; it’s not welded inside the head like a pipe fitting. So how is it calculated?
Dizzy! ! If there are no holes and it’s simply welded to the head, you only need to calculate mechanical stress, shear force, etc
Take a look at HG20582-1998.
