Corrosion Flange

Corrosion Flange

In the calculation of Flange what is the different between Bore Corrosion and Flange Corrosion?

RE: Corrosion Flange

Bore corrosion allowance is subtracted from the thickness of the hub. Flange corrosion allowance is subtracted from the thickness of the "flange" (where the bolts go through).

For example, Appendix 2 provides formulas for calculated stress in the flange based on flange thickness "t". COMPRESS determines "t" as the nominal (specified) thickness of the flange minus the flange corrosion allowance.
