I have a question regarding flanges

2018-12-21View Original

Thread Content

When using SW-2011 for calculations, for the inner diameter Di of the gasket flanges of NBT47021~47022, should it be the inner diameter of the sleeve (the inner diameter of the cylinder), or the inner diameter of the flange itself (the outer diameter of the sleeve + 4mm)? If the inner diameter of the flange body is entered, the calculated thickness will be thicker than that based on the inner diameter of the liner.

Type A flanges are calculated based on arbitrary flanges, while type B flanges are calculated based on integral flanges (2); in both cases, it is the inner diameter of the cylinder that is considered, and the lining is only used for corrosion resistance and is not taken into account in the calculations.
