摘要： So as to embody an assembly whose imperviousness is obtained with slight gripping power and may be kept at high pressure and at a high temperature, the invention concerns proposing a gasket or joint which includes an elastic metal core with a circular section and at least one external casing made of a hard metal. The casing comes and takes support on the flanges of the assembly by projecting parts with a triangular section and having an annular surface in contact with the flanges whose width is at the most equal to about 0.05 mm once the gripping power has been applied.

摘要： A flexible metal sealing joint comprising an elastic metal core which, in the rest position, is shaped like a torus, as well as at least one outer envelope made from a ductile material. Within its thickness, the outer envelope has two substantially planar bearing surfaces and at least one projecting portion with a substantially triangular cross-section formed on each of the bearing surfaces. The dimensions of the projecting portions are such that said portions are expendable, i.e. they disappear at the end of fixing.
