The concept of the effective gasket width is used in the ASME code for flange designs to account for flange rotation. Its origin has never been revealed and it is suspected that only limited experimental testing was conducted for verification. In addition, with the new design rules based on the new gasket constants obtained from ROTT tests conducted on rigid platens, there is a need to revise the effective gasket width formulas.
This Bulletin presents the work of Project 04-01 conducted under the auspices of the PVRC and related to the investigation of the effect of the non-uniform gasket contact stress due to flange rotation on the leakage behavior of sheet gasket materials. A numerical investigation coupled to some experimental findings obtained from PVRC Project 98-04 was conducted to determine the effective gasket width for raised face flanges and its variation with gasket type, flange flexibility and load.
