SEAL ASSEMBLY AND CORRESPONDING TUBULAR JOINT

摘要

The invention relates to a seal assembly for a tubular joint, comprising a seal lining defining a central axis (X-X), and at least one anti-extrusion element (10) for preventing the extrusion of the seal lining (8) between a spigot end (6) and a fitting end (4) of the tubular joint. The anti-extrusion element comprises at least one first bend recess for enabling a radial bend of the anti-extrusion element, and the radial bend rigidity of the anti-extrusion element (10), at the circumferential location of the or each bend recess, is less than 50% of the radial bend rigidity of the circumferential locations without bend recesses. The invention can be used for tubular joints.
