When calculating the reinforcement for openings using SW6, the actual outward extension height of the nozzle

Thread Content

When using SW6 to calculate reinforcement for openings, does the actual outward extension height of the pipe fitting include the thickness of the flange itself, such as in the case of plate-type butt weld flanges?

Hello, which book does this screenshot come from?

Not included; finite element analysis indicates over-safety

Same question: which book is this from? It has always been done this way before, but there are no books as a reference.

From \"Common Issues in the Design and Manufacturing of Pressure Vessels\", Supplement to \"Fertilizer Design\" 2000 (Issue No. 198), Chapter 5: Calculations

The equal-area reinforcement method – I don’t see any mistake in including the thickness of the flange. And even if we count only the takeovers, it’s still an underestimation

In actual reinforcement calculations, the protrusion height of the nozzle should preferably not include the flange.

Common issues in the design and manufacturing of pressure vessels. I have this book, but I don’t know how to upload an attachment :(
