How to verify the load-bearing capacity of the stirrer tube flange
Thread Content
Help: There is a mixing equipment that is connected to the mixing unit via a coupling flange. The mixing parameters have been changed, so the mixing power has also been increased by one level. The mixing supplier said that the original size of the mixing port (PN10, DN250) can be used. The stirrer supplier provided gravity, shear, torque, and bending moment loads. I would like to ask the experts: how can we determine the load-bearing capacity of this pipe flange under new loads?
This field is quite specialized, and calculations require many technical parameters; therefore, such calculations are usually carried out by professional manufacturers. Your company can request these calculations from the manufacturers. However, in general, the flange design for mixer installation includes a margin of safety; with only an increase in power level, the manufacturers’ claim that the existing flange can still be used is generally reliable.
For pressure vessels, just perform verification on the tank mouth flange!
