  • Extrusion preventing device for incorporation into a sealing element and a well tool device comprising a sealing element in which such an extrusion preventing device is incorporated
    Patent number: 11879302
    Abstract: An extrusion preventing device for incorporation into a sealing element of a well tool device includes a wire wound with a plurality of turns to form a torus-shaped coiled spring. Each turn of the torus-shaped coiled spring is canted. A method for manufacturing a sealing element for a well tool device includes providing a mould shaped as the sealing element; inserting an extrusion preventing device including a wire wound with a plurality of turns to form a torus-shaped coiled spring into the mould; filling molten elastomeric material into the mould, thereby incorporating the torus-shaped coiled spring into the molten elastomeric material; curing the elastomeric material; and retrieving the sealing element from the mould.
