Bolt Length Calculation for General Wafer Components

The calculation of bolts through wafer components is similar to the standard flange-gasket-flange calculation, with the following differences:

• If within the joint, a component’s connection type starts with W (wafer), get its P1 - P2 distance, and go to the next component.

• The joint may contain any number of wafer components, (for example, butterfly valves, orifice plates, spectacle plates, spades) and any number of gaskets. The total bolted through length will be summed and added to the flange thickness.
