Gaskets effective width

B, = bolt spacing, in. b = effective gasket width, in. b() = gasket seating width, in. 

Here Wmi is the gasket seating load, b is the effective gasket seating width, and G is the minimum gasket diameter. When the joint is pressurized by the fluid in the pressure vessel, the operating bolt load, W i is given by... 

Figure 9.4 gives the schematic drawing of the cover flange. The gasket reaction location and the effective width are calculated as follows ... 

Select an effective plate area of 0.75 m2, effective length 1.5 m and width 0.5 m these are typical plate dimensions. The actual plate size will be larger to accommodate the gasket area and ports.
