Div.2 is better suited for heavy vessels, where the increased cost of design (and of testing) may be balanced by the lower overall weight obtained for the equipment.

Don't forget that VIII Div. 2 is being completely rewritten. Not a revision of the existing document. They started from scratch. I believe the new Div. 2 is targeted for a release in June '06. Anyone have an update?

Thus can't easily unload div. 2's on the used equipment market afetr your plant gets closed.

Meanwhile div.1 uses the maximun principal stress, div.2 uses the maximun shear stress (like Ad-Merkblatt).
In the formula of div. 2 should be a term p/2, which is the radial stress averaged along the wall thikness (=-p in the inside of the vessel and =0 outside)
