There is provided a turbine engine component, such as a duct pipe, comprising an annular flange, at least one element, such as two duct pipe halfs, to be mated to the flange, and mating system for joining the at least one element to the flange. The mating system includes a first annular groove in the flange, which groove has two opposed planar wall portions for preventing axial movement of the at least one element relative to the flange. In a preferred embodiment, the mating system also includes a second annular groove in the flange. A sealing element is positioned within the second annular groove.

The turbine engine component according to claim 1, further comprising said annular groove having a flat portion connecting said two planar wall portions. 3. The turbine engine component according to claim 1, further comprising said annular groove having an angled wall portion adjacent one of said planar wall portions for providing hoop strength. 4. The turbine engine component according to claim 3, further comprising said at least one element having a mating angled wall portion which contacts said angled wall portion on said flange. 5. The turbine engine component according to claim 4, wherein said at least one element further has a tongue adjacent said mating angled wall portion and said tongue fitting between said two planar wall portions of said groove. 6. The turbine engine component according to claim 4, wherein mating system further comprises a second annular groove in said flange and a sealing element seated in said second annular groove and wherein said at least one element further has a substantially planar portion adjacent said mating angled wall portion for overlapping said second annular groove and abutting said sealing element. 7. The turbine engine component according to claim 6, wherein said sealing element comprises an O-ring. 8. The turbine engine component according to claim 6, wherein said at least one element comprises a first semi-annular component and a second semi-annular component for mating with said flange. 9. The turbine engine component according to claim 8, further comprising said first semi-annular component having a first connection element, said second semi-annular component having a second connection element which aligns with said first connection element, and fastener means for joining said first connection element to said second connection element, whereby when said first connection element is joined to said second connection element said sealing element is compressed by said first and second semi-annular components. 10. The turbine engine component according to claim 9, further comprising one of said semi-annular components having a door for gaining access to said fastener means and a deflectable baffle assembly. 11. The turbine engine component according to claim 10, wherein said deflectable baffle assembly comprises a plurality of baffle members joined to said one of said semi-annular components. 12. The turbine engine component according to claim 1, wherein said rotation preventing means comprises an anti-rotation pin joined to said flange and said at least one element has a slot for receiving a portion of said anti-rotation pin. 13. The turbine engine component according to claim 1, further comprising: said mating means including a second annular groove in said flange; and said second annular groove having two opposed planar wall portions for preventing axial movement of said at least one element relative to said flange. 14. The turbine engine component according to claim 13, wherein said at least one element has two spaced apart tongue members for engaging said first and second annular grooves. 15. The turbine engine component according to claim 14, further comprising a third annular groove in said flange, a sealing element in said third annular groove, and said at least one element having a substantially planar portion for compressing said sealing element. 16. The turbine engine component according to claim 15, wherein said sealing element comprises an O-ring. 17. The turbine engine component according to claim 15, wherein said third groove is positioned between said first and second grooves. 18. The turbine engine component according to claim 1, further comprising: said mating means including a second annular groove in said flange; and said second annular groove being substantially V-shaped for preventing movement of said at least one element relative to said flange. 19. The turbine engine component according to claim 18, wherein said substantially V-shaped groove has a first planar wall, a second planar wall at an angle with respect to said first planar wall, and a third planar wall joining said first and second walls. 20. A turbine engine component comprising: an annular flange; at least one element to be mated to the flange; mating means for joining said at least one element to said flange, said mating means including a first annular groove in said flange; said first annular groove having two opposed planar wall portions for preventing movement of said at least one element relative to said flange; and said mating means further comprising means for allowing said at least one element to be locked and unlocked relative to said flange. 21. The turbine engine component according to claim 20, wherein said means for allowing said at least one element to be locked and unlocked comprises a pin inserted into a slot in said flange and a bayonet slot in an end wall of said at least one element. 22. The turbine engine component according to claim 21, wherein said bayonet slot has a notch that allows said at least one element to move between a locked position and an unlocked position. 23. A turbine engine component comprising: an annular flange; at least one element to be mated to the flange; mating means for joining said at least one element to said flange, said mating means including a first annular groove in said flange; said first annular groove having two opposed planar wall portions for preventing movement of said at least one element relative to said flange; and means for joining said flange to a mating body. 24. The turbine engine component according to claim 23, wherein said joining means comprises a full hoop flange assembly incorporated into said mating body and a flange retention bolt which passes through said annular flange and wherein said flange retention bolt fits into said full hoop flange assembly. 25. An annular flange comprising: a first annular groove in said flange; said first annular groove having a first planar wall and a second planar wall; a third planar wall adjacent said second planar wall, said third planar wall being angled with respect to said second planar wall so as to form a substantially V-shaped groove with said first planar wall; and a leading edge and a first slot in said leading edge for receiving an anti-rotation pin. 26. The annular flange according to claim 25, wherein said first planar wall has a length greater than the length of said second planar wall. 27. annular flange according to claim 25, further comprising a second annular groove for receiving a sealing element. 28.
