Clamped flange fitting assembly.

摘要

A clamped flange pipe or tube fitting (10) assembly includes a resilient seal ring (50) compressed in a chamber (30) formed by cooperating recesses in opposed flanges (18,18'). The chamber (30) and seal ring (50) are dimensionally related in a manner to produce circumferentially continuous, radially spaced primary and secondary seal areas (42,46) and to assure a continuous interior surface between the connected pipes or tubes (12,14) with no recesses to entrap process fluids.
