Abstract: A sealing assembly for attaching pliable tubes to rigid connecting members, for high pressure, low temperature service, which seals by compressing a sealing wafer around the pliable tubes. The pliable tubes pass through holes in the sealing wafer. As the wafer seal is axially compressed, the wafer seal is restrained against radial expansion, thereby exerting an inward radial pressure on the holes through the wafer seal to cause an hermetic seal between the wafer seal and the pliable tubes. A swage bushing can be used, with swage tubes that are swaged onto the pliable tubes by a swage clamp, for the purpose of axially restraining the pliable tubes.

In a preferred embodiment, the seal is provided by a brush seal secured to one of the seal ring segments and received in a slot defined in the other of the seal ring segments.

Abstract: A sealing method and apparatus involves positioning sealant carriers in a gap between first and second components to be sealed. Sealant is applied to a first major surface of the sealant carriers. As the first and second components are tightened together, the carriers are compressed and cause sealant to travel from the first major surface and through the carriers to a second major surface which is opposed to the first major surface. The sealant carriers may be positioned on respective carrier supports while sealant is being applied to the first major surface of the sealant carriers. The supports are used in initially positioning the sealant carriers in place and then are removed prior to tightening the first and second components together. The supports may include alignment mechanisms for use in aligning the sealant carriers with one of the first and second components. The sealant adheres the sealant carriers to such one of the first and second components following removal of the supports.

Abstract: A plurality of arcuate, circumferentially extending leaf seal segments form an annular seal spanning between annular sealing surfaces of inner and outer casings of a turbine. The ends of the adjoining seal segments have circumferential gaps to enable circumferential expansion and contraction of the segments. The end of a first segment includes a tab projecting into a recess of a second end of a second segment. Edges of the tab seal against the sealing surfaces of the inner and outer casings have a narrow clearance with opposed edges of the recess. An overlying cover plate spans the joint. Leakage flow is maintained at a minimum because of the reduced gap between the radially spaced edges of the tab and recess, while the seal segments retain the capacity to expand and contract circumferentially.
