A static metal seal comprising an outer sealing layer, wherein the outer sealing layer comprises a textured surface that is configured to come into contact with the surfaces that are to be sealed, the textured surface comprising a network of depressions spaced apart from one another on the textured surface, wherein the depressions are blind, do not pass all the way through the outer sealing layer, and do not communicate with one another.

An annular assembly for compressing a seat of a ball-valve, including: a valve body or insert, including an annular internal counter-bore that defines an inner counter-bore diameter; a sleeve inserted into the annular internal counter-bore, defining at least one outer diameter of the sleeve; the body or the insert defining with the sleeve an annular housing in which the assembly includes, in succession: a downstream stack of head rings, an annular head shim, a stack of mechanisms of compression, an annular base shim, and an upstream stack of base rings.

A method including placing around the shoulder of the lid a ring-shaped gasket formed by a metal strip maintained on the vertical wall of the shoulder by self-maintaining members firmly attached to the strip, placing the lid bearing the ring-shaped gasket above the vessel by positioning it at a determined height, carrying out a cleanliness inspection of the gasket plane, lowering and laying the lid on the vessel so that the end side edges of the strip will come into contact with a horizontal wall of the lid and of the vessel flange respectively and attaching this lid on the vessel.
