Knowing the pressure and inner diameter, how to select an annular size with a similar dimension according to Appendix C of 150.3, Table C.7? Can I choose according to Table 4-1 of HGT20633? As shown in Figure 2 below, if the structure is designed as a cylinder end, then on page 150.3, P203, what value does D2 represent in the structural dimensions of the cylinder end? Is it the outer diameter of the octagonal, elliptical gasket sealing groove?
Yes, determine the diameter of the circle centered on the bolt hole
How to choose a gasket? Is it sufficient if it has an inner diameter? :Q
The table shows the gaskets used for standard flanges; if they are to be used for equipment, designs can be created on their own by referring to the table.
