Pairs of Flanges

A connected pair of identical Flanges will be represented by two adjacent symbols, but the identifying material list number will be shown only once. Only one gasket and one set of bolts will be called up for each pair of Flanges.

Single material list number for a pair of matched flanges

Where the connected Flanges have different codes, separate material list numbers will be shown. In this case, the associated Gasket and Bolt identifying numbers will be attached to the second Flange of the pair only.
