An internally insulated bellows assembly for providing a flexible transition between internally and externally insulated components of a high temperature fluid pressure system comprises an annular bellows having first and second end portions, a cylindrical shield disposed in spaced, concentric relation within the bellows and coextensive therealong to provide an annular cavity therebetween. The shield has first and second end portions with the first end portions being connected to the first end portion of the bellows and with the second end portion being disposed in spaced radial relationship inwardly from the second end portion of the bellows to provide a predetermined radial gap therebetween. Loose fill insulation material is disposed within the cavity to a point adjacent the second end portion of the shield in filling relation within the internal convolutions of the bellows. An annular ring of constrained insulation sized for close fitting receipt within the cavity is provided for closing the gap between the end portions of the shield and the bellows. |
