Metal gasket or joint provided with an extremely high unit-area pressure
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.
