Abstract:
A sealing gasket intended to be clamped between two pipework connection flanges, said gasket comprising a sealing ring including a rigid metal annular part, with which are integral a number of radiating metal lugs which can be folded along the contour of a support flange,wherein, said sealing gasket having to be able to be used with flanges of different transverse dimensions, said metal lugs are longer than the corresponding transverse dimension of the largest flanges on which the gasket can be mounted and are provided with markers corresponding to pre-specified dimensions of flanges, whereby, before the gasket is mounted on a flange, the lugs can be folded to conform with the exact dimension of said flange so that the gasket may be supported by said flange while being suitably centered before the two flanges are connected together.
