An arrangement in which an inner cylindrical casing is connected to a concentric outer cylindrical casing, the arrangement comprising: an inner cylindrical casing (12); an outer cylindrical casing (11) concentric with the inner cylindrical casing (12); and a connector (13,24,31) connecting the inner and outer cylindrical casings (12,11), whereby the connector (13,24,31) comprises a cylindrical connector (13,24,31) disposed between and concentric with the inner and outer cylindrical casings (12,11), wherein the cylindrical connector (13,24,31) is stiff in the direction of the concentric axis (A) but flexible in the direction radially with respect to the concentric axis (A) such that relative thermal expansion of the inner and outer cylindrical casings (12,11) in the radial direction is permitted whilst simultaneously maintaining the relative position of the casings (12,11) in the axial direction. |
