Abstract

A self-energizing seal element includes at least one inside interference surface having a dimension smaller than an inside dimension of an annulus in which the seal is to be disposed in use, at least one outside interference surface hav ing a dimension larger than an outside dimension of the annulus in which the seal is to be disposed in use, the at least one inside interference surface being axially offset from the at least one outside interference surface and at least one angular flange extending between the at least one outside interference surface and the at least one inside interference surface and method for sealing.

Claims

AMENDED CLAIMS received by the International Bureau on 30 January 2009 (30.01.09)
1. A self-energizing seal element comprising: at least one inside interference surface having a dimension smaller than an inside dimension of an annulus in which the seal is to be disposed in use; at least one outside interference surface having a dimension larger than an outside dimension of the annulus in which the seal is to be disposed in use, the at least one inside interference surface being axially offset from the at least one outside interference surface; at least one angular flange extending between the at least one outside interference surface and the at least one inside interference surface; at least one groove at an inside aspect of the element or at an outside aspect of the element directly radially inwardly of the at least one outside interference surface or directly radially outwardly of the at least one inside interference surface respectively; and at least one seal component positioned within the at least one groove.
2. The self-energizing seal element as claimed in claim 1 wherein the element further includes end housings bounding the element.
3. The self-energizing seal element as claimed in claim 1 wherein the at least one outside interference surface is two outside interference surfaces.
4. The self-energizing seal element as claimed in claim 3 wherein two outside interference surfaces have equal outside dimensions.
5. The self-energizing seal element as claimed in claim 3 wherein two outside interference surfaces have unequal outside dimensions.
6. The self-energizing seal element as claimed in claim 1 wherein at least one inside interference surface is two inside interference surfaces.
7. The self-energizing seal element as claimed in claim 6 wherein two inside interference surfaces have equal inside dimensions.
8. The self-energizing seal element as claimed in claim 6 wherein two inside interference surfaces have unequal inside dimensions.
9
9. (Canceled)
10. (Canceled)
11. The self-energizing seal element as claimed in claim 1 wherein the seal component is elastomeric.
12. The self-energizing seal element as claimed in claim 1 wherein the seal component is soft metal.
13. The self-energizing seal element as claimed in claim 1 wherein the dimension larger than an outside dimension of the annulus in which the seal is to be disposed in use is larger by about 0.015"
14. The self-energizing seal element as claimed in claim 1 wherein the dimension smaller than an inside dimension of the annulus in which the seal is to be disposed in use is smaller by about 0.015".
15. A method for creating a metal to metal seal between at least a seal element and a component at an outside dimension of a seal element, the method comprising: urging the element axially into contact with the component; interferingly engaging at least a maximum annular dimension of the element with the component; and inducing axial extension of the element to produce sealing stress in the element.
16. A method for creating a metal to metal seal comprising: urging a first tubular member into a second tubular member, one of the first or second tubular members carrying a metal seal element; elongating the seal element through interference with the other of the first or second tubular members; and inducing a radial expansion stress in the element against the tubular interfering with the element.
17. The method as claimed in claim 16 wherein the interfering fit is at both the first and second tubulars.
10
18. The self-energizing seal element as claimed in claim 1 wherein the seal component is entirely confined within the groove housing it.
19. The self-energizing seal element as claimed in claim 1 wherein the seal component is made of a material less robust than a material of the element.
