Fastener

摘要

The present invention provides a fastener for securing two pipe adapters within a casing such as a gas turbine casing. The fastener comprises a fastener body having a central bore for receiving the pipe adapters and having a first engagement portion, e.g. a radial projection extending into said central bore, for engagement with a first pipe adapter. The central bore has a second engagement portion, e.g. a threaded portion, for engagement with a second pipe adapter. The fastener further comprises an outer wall at least partly surrounding and spaced from the fastener body in a concentric arrangement. The outer wall comprises a fastener flange extending radially in a direction away from the fastener body for overlaying the casing. At least a portion of the outer wall is deformable (e.g. formed as bellows) so that, in use, axial and/or radial movement of the pipe adapters is dampened.

1. A fastener for connecting two pipe adapters within a casing, the fastener comprising
a fastener body having a central bore with a first engagement portion for engagement with a first pipe adapter and a second engagement portion for engagement with a second pipe adapter; and an outer wall at least partly surrounding and spaced from said fastener body, wherein:
the outer wall has a first end directly connected to the fastener body,the outer wall comprises a fastener flange extending radially in a direction away from said fastener body for overlaying the casing such that a free end of the fastener flange is spaced from the fastener body, andat least a portion of the outer wall is deformable in use so as to dampen axial and/or radial movement of the pipe adapters.
