ABSTRACT:
A structure for extreme thermal cycling has a support element that supports a vessel primarily by bearing and frictional forces rather than by welds. The support element has a bearing portion that tapers inwardly beneath a knuckle that separates a cylindrical section of the vessel from a sloped lower section. The bearing portion of the support element follows that slope, providing an extended area of contact between the support element and the vessel. An annular section of the support element can be heated and expanded before placing it around the cylindrical section of the vessel to provide pre-stressing. If required, a strap may extend downwardly from the vessel over an upper edge of the support element.
