This post was last edited by forowhl on 2023-3-4 09:23. I have a question: as shown in the figure below, when using sw6 to calculate the flange cover, should 57mm or 51mm be used as the value? PS: The 51mm area is the location of the sealing surface.

I used to enter the value as 57mm as well; recently, I took a closer look at the thickness of the convex flange in the NB47023, and found that it is indicated as only 45mm thick.

1. Flange cover thickness； 2. The flange thickness of the flange cover is 2 dimensions!

Thank you, I’ve found the source; it’s indicated in the diagram of bolted flat covers on page 139 of GB150.
