연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A juncture assembly is provided between first and second ends of respective first and second tubes. The assembly includes a first flange that is located at the first end and a second flange that is located at the second end, with the second flange being in confronting relationship with the first flange. The first and second flanges define a gap between them. A gasket member contacts the first and second flanges and is configured to prevent flow of fluids through the gap. A clamp member of the assembly secures the gasket member to the first and second fla...

1. A clamp assembly for joining first and second confronting flanges located at the longitudinal ends of respective first and second tubes, the flanges defining a gap therebetween, the assembly comprising: a gasket member contacting the first and second flanges and configured to prevent flow of fluids through the gap; andan annular clamp member including a first lateral portion and a second lateral portion confronting each other and defining a channel therebetween for receiving the first and second flanges, said first lateral portion including a first plurality of circumferentially spaced restriction elements extending into said channel and said second lateral portion including a second plurality of circumferentially spaced restriction elements extending into said channel for positioning the first and second flanges within said channel. 2. The clamp assembly of claim 1, wherein said first plurality of restriction elements and said second plurality of restriction elements are disposed on opposite sides of said channel across a cross-sectional axis of said clamp member. 3. The clamp assembly of claim 2, wherein said first plurality of restriction elements and said second plurality of restriction elements are disposed in confronting relationship with one another across the cross-sectional axis of said clamp member. 4. The clamp assembly of claim 2, wherein said clamp member extends along a generally close-ended path. 5. The clamp assembly of claim 4, wherein the close-ended path is generally circular. 6. The clamp assembly of claim 1, wherein said gasket member is disposed in the gap between the first and second flanges, said first plurality of restriction elements and said second plurality of restriction elements contacting the first and second flanges to retain said gasket member in place. 7. The clamp assembly of claim 1, wherein said gasket member is supported by respective first and second radial ends of the first and second flanges and is deformable about said first and second radial ends of the first and second flanges, said first plurality of restriction elements and said second plurality of restriction elements being positioned to prevent movement of said gasket member relative to said channel. 8. The clamp assembly of claim 7, wherein said gasket member has one of a generally round or a generally half-round cross-sectional profile when said gasket member is in its undeformed condition. 9. The clamp assembly of claim 1, wherein at least one of said first plurality of restriction elements or said second plurality of restriction elements includes a protruding deformed portion of said clamp member. 10. The clamp assembly of claim 9, wherein said protruding deformed portion has a generally rounded cross-sectional profile. 11. The clamp assembly of claim 9, wherein said protruding deformed portion has a generally quadrilateral cross-sectional profile. 12. The clamp assembly of claim 9, wherein at least one of said first plurality of restriction elements or said second plurality of restriction elements protrudes from a notch formed in said clamp member. 13. The clamp assembly of claim 1, wherein at least one of said first plurality of restriction elements or said second plurality of restriction elements includes a plate coupled to said clamp member and having a bent portion extending into said channel. 14. An annular clamp member for securing respective longitudinal ends of first and second tubes to one another, the longitudinal ends of the first and second tubes having respective first and second flanges, the clamp member comprising: a first lateral portion and a second lateral portion confronting each other and defining a channel therebetween for receiving the first and second flanges therein; anda first plurality of circumferentially spaced restriction elements supported by said first lateral portion and extending into said channel and a second plurality of circumferentially spaced restriction elements supported by said second lateral portion and extending into said channel, said first plurality of restriction elements and said second plurality of restriction elements being configured to position the first and second flanges within said channel. 15. The clamp member of claim 14, further comprising: a gasket member located in said channel, said first plurality of restriction elements and said second plurality of restriction elements being positioned to prevent movement of said gasket member relative to said channel. 16. The clamp member of claim 14, wherein said first plurality of restriction elements and said second plurality of restriction elements are disposed on opposite sides of said channel across a cross-sectional axis of said clamp member. 17. The clamp member of claim 16, wherein said first plurality of restriction elements and said second plurality of restriction elements are disposed in confronting relationship with one another across the cross-sectional axis of said clamp member. 18. The clamp member of claim 16, wherein said clamp member extends along a generally close-ended path. 19. The clamp member of claim 18, wherein the close-ended path is generally circular. 20. The clamp member of claim 14, wherein said first plurality of restriction elements and said second plurality of restriction elements are positioned to contact the first and second flanges to thereby retain a gasket member in a gap defined between the first and second flanges. 21. The clamp member of claim 14, wherein at least one of said first plurality of restriction elements or said second plurality of restriction elements includes a protruding deformed portion of said clamp member, said protruding portion having one of a generally rounded cross-sectional profile or a generally quadrilateral cross-sectional profile. 22. The clamp member of claim 21, wherein at least one of said first plurality of restriction elements or said second plurality of restriction elements protrudes from a notch formed in said clamp member. 23. The clamp member of claim 14, wherein at least one of said first plurality of restriction elements or said second plurality of restriction elements includes a plate coupled to said clamp member and having a bent portion extending into said channel. 24. The clamp member of claim 14, wherein said first plurality of restriction elements and said second plurality of restriction elements are positioned to center the first and second flanges within said channel.
