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.

초록

Connection assembly includes two pipe end sections arranged to face each other, a profiled clamp including a clamping band with a base and two tilted side walls with ends, and at least one perimeter pleat projecting outwards on each of the pipe end sections. The side walls are engagable with the pleats on sides of the pleats facing away from one another.

1. A connecting assembly comprising: two pipe end sections arranged to face each other;a profiled clamp including a clamping band with a base and two tilted side walls with ends, wherein the base is arranged between the two tilted sidewalls in an axial direction;at least one perimeter pleat projecting outwards on each of the pipe end sections wherein the pleats have a straight region running in the radial direction and a rounded region radially outward the straight region; andan annular sealing element arranged between the two tilted side walls,wherein the side walls are engagable with the rounded region of the pleats on sides of the pleats facing away from one another, respectively,wherein each pleat is positioned at a distance from an end of its respective pipe end section,wherein, in an assembled state, an entire width of the base in the axial direction is smaller than a distance in the axial direction between the pleats on each of the pipe end sections,wherein in a tightened state of the clamping band the side walls abut against the rounded region of the pleats on sides of the pleats facing away from one another, and the sealing element abuts against the base and the side walls, and the sealing element having tapered walls that abut against the rounded region of the pleats on sides of the pleats facing towards one another,wherein the pipe end sections have an identical diameter, andwherein the pipe end sections face one another at their front faces. 2. The connecting assembly according to claim 1, wherein the pipe end sections bear against one another at their front faces. 3. The connecting assembly according to claim 1, wherein the sealing element has recesses in regions of the ends of the side walls. 4. The connecting assembly according to claim 3, wherein the recesses are smaller than the pleats. 5. The connecting assembly according to claim 1, further comprising an insert sleeve on a radial inside of the sealing element. 6. The connecting assembly according to claim 5, wherein the insert sleeve is positionable to cover a gap between the pipe end sections. 7. The connecting assembly according to claim 1, wherein the sealing element has an annular element on a radial inside portion that extends into a gap between the pipe end sections. 8. The connecting assembly according to claim 7, wherein the annular element is embodied in one piece or in two pieces with the sealing element. 9. The connecting assembly according to claim 1, wherein each pleat is formed having internal walls of the respective pipe end section in contact with one another at the pleat. 10. A method for producing a connection of two pipe end sections comprising: positioning two pipe end sections to face each other, each of the pipe end sections having at least one pleat projecting radially outwards, wherein each of the at least one pleat is positioned at a distance from an end of its respective pipe end section, and wherein the pleats have a straight region running in the radial direction and a rounded region radially outward the straight region,locating a profiled clamp over the pleats, the profiled clamp including a clamping band having a base and two side walls, wherein the base is arranged between the two tilted sidewalls in an axial direction and wherein the profiled clamp includes an annular sealing element arranged at an inner side of the profiled clamp; andadjusting an axial distance between the pleats through a radial movement of the sidewalls such that an entire width of the base in the axial direction is smaller than the distance in the axial direction between the respective at least one pleats,wherein in a tightened state of the clamping band the side walls abut against the rounded region of the pleats on sides of the pleats facing away from one another, respectively, and the sealing element abuts against the base and the side walls, and the sealing element having tapered walls that abut against the rounded region of the pleats on sides of the pleats facing towards one another,wherein the pipe end sections have an identical diameter, andwherein the pipe end sections face one another at their front faces. 11. The method according to claim 10, further comprising pressing the pipe end sections radially and at the same time axially towards each other by via the sidewalls. 12. The method according to claim 10, wherein the adjusting comprises tightening the clamping band so that the pleats slide along the side walls and move towards each other. 13. The method according to claim 10, wherein the two side walls extend obliquely from the base. 14. A profiled clamp connection comprising: two pipe end sections, each of the pipe end sections having at least one perimeter pleat, wherein the at least one pleat of each of the pipe end sections is positioned at a distance from an end of its respective pipe end section, and wherein the pleats have a straight region running in the radial direction and a rounded region radially outward the straight region; a clamping band having a base and two tilted side walls, wherein the base is arranged between the two tilted sidewalls in an axial direction, and wherein an entire width of the base in the axial direction is smaller than a distance in the axial direction between the respective at least one pleat of each of the pipe end sections;an annular sealing element located between the two tilted side walls; andrecesses formed between a part of the two tilted side walls and the annular sealing element to form a slide surface for the pleats,wherein in a tightened state of the clamping band the side walls abut against the rounded region of the pleats on sides of the pleats facing away from one another, respectively, and the sealing element abuts against the base and the side walls, and the sealing element having tapered walls that abut against the rounded region of the pleats on sides of the pleats facing towards one another,wherein the pipe end sections have an identical diameter, andwherein the pipe end sections face one another at their front faces.
