Abstract:
1. A gasket seal comprising: a sealing ring having an outer contour surface, a lower surface and an upper surface; and a rigid centralization ring to centralize the sealing ring between the flanges of piping and equipment, having an inner contour surface, lower surface and upper surface, the inner contour surface defining a central opening, into which the sealing ring fits; the outer contour surface of the sealing ring having a substantially L-shaped configuration, comprising an innermost portion and an outermost portion extending axially, and a radial portion, which interconnects the innermost portion and the outermost portion, wherein the opening of the centralization ring substantially coincides with said innermost portion, so that the sealing ring can be inserted into the opening of the centralization ring as far as the radial portion, making contact with one of the upper or lower surfaces of the centralization ring; the innermost portion further includes a deformation projecting outwards and located axially apart from the radial portion, so that the centralization ring will be retained on one side by the deformation, and on the other side by the radial portion.
