Abstract: A gasket seal for piping and equipment flanges comprises a sealing ring and a centralization ring, preferably concentric rings made of a metallic alloy. The sealing ring has an outer contour surface having a substantially L-shaped cross-section comprising an innermost portion and an outermost portion extending axially and a radial portion interconnecting the inner and the outer portions. The centralization ring has an inner contour surface defining a central opening, substantially coincident with the innermost portion of the outer contour surface of the sealing ring, so that the latter can be fitted into the opening as far as the radial portion of its outer contour surface. A deformation is made on the innermost portion of the outer contour surface of the sealing ring, forming a projection, whereby the centralization ring can be retained between the projection and radial portion without the centralization ring needing to be separated and then welded.

Abstract: The present invention constitutes a sealing means for piping and equipment flanges, especially of the Camprofile-type. The gasket of the present invention comprises a sealing ring (100) and a centralization ring (120) to centralize the sealing ring on the flanges of piping or equipment. Preferably, the sealing ring and the centralization ring are concentric rings made of a metallic alloy. The sealing ring has an outer contour surface (118), a lower surface (115) and an upper surface (117), the upper and lower surfaces consisting, respectively, of lower and upper prolongations of the outer contour surface. The outer contour surface has a substantially L-shaped cross-section comprising an innermost portion (118a) and an outermost portion (118b) extending axial and a radial portion interconnecting the inner and the outer portions. The centralization ring (120) comprises an outer contour surface (128), an inner contour surface (126), a lower surface (125) and an upper surface (127).
