Abstract
Joints for high temperature and high pressure conduits are disclosed wherein two conduit members are joined in such a manner that permits axial and radial movement due to temperature variations therein while at the same time provides sealing of the joints by means of segmented sealing rings disposed in grooves and extending into a space defined by a sleeve-like extension on one conduit member and a bushing like extension on a second conduit member.
Claims5
A joint for high temperature and high pressure conduits comprising:
- a first hollow ring holding member comprising a pressure housing extending from a first conduit member and surrounding a second hollow bushing like member comprising a gas conduit housing extending from a second conduit member and defining a space between said first and second hollow members;
- at least one annular groove in said first hollow member opening toward said space;
- at least one ring disposed in each groove and extending into said space in sealing relationship to said first and second hollow members, said ring including a plurality of segments separate from and contiguous with each other;
- a plurality of separate helical springs disposed radially from said annular groove in said first hollow member coupled with each ring and biasing each ring segment radially inward in sealing relationship to said second hollow member;
- whereby said segmented rings compensate for axial and radial motion of said members due to temperature variations therein.
