    摘要: A spiral wound gasket (10) with increased resistance to an inward buckling while sealing flanges at low stress levels, in which an outer guide ring (14) for positioning the gasket within the bolt circle of a bolted flange connection connects to a sealing element (12) having a core (16) that contributes to gasket recovery and made of a spirally wound, chevron-shaped band overlaid by a layer (20) of sealing material covering at least a portion of opposing sides of the core to conformably seal contact faces of flanges to be sealed.
