摘要： A turbomachinery gasket comprising at least a first curved elongated element having a coupling part configured to cooperate with a tubular assembly in order to keep the gasket in position on the tubular assembly, and an outer surface configured to seal against an outer casing provided to house the tubular assembly, the first curved elongated element comprising a first and a second free end, the first free end providing a first protruding lip and the second free end providing a second protruding lip, the first protruding lip being configured to overlap with the second protruding lip of the first curved elongated element or with a second protruding lip of a second elongated element functionally identical to the first one, so that, when the gasket is in use, a seal in that part of the gasket having said protruding lips is granted.

摘要： A dry gas seal for sealing the shaft of a turbomachinery, provided with means for the continuous health monitoring of the dry gas seal comprising one or more sensors adapted to measure strains and/or loads induced to the primary ring of the dry gas seal and/or strains induced to one or more of the elastic elements coupled to the primary ring and/or adapted to measure displacements of the primary ring or of an element coupled to the primary ring, for an early detection of failure of the seal, thus enabling main failures early detection capability and proactive maintenance actions.
