Thought question 8: When calculating the flange of the sw6 container, the thickness entered for the flange represents the effective thickness, while the thickness of the flat cover connected to the flange is the nominal thickness. How do you determine these values? For example, the flange thickness is equal to the length of the bolt hole.

The flange thickness corresponds to the input value of C; this value does not affect the reduction in corrosion, while the nominal thickness plus corrosion allowance is entered for the flange cover

Refer to GB/T150.3 Flanges 7.1.2 (d) for stress verification; all dimensions used in the calculations do not include a corrosion allowance.
