Description

one

The invention relates to the type of hermetic one-piece joints obtained by the method of flaring, especially when joining pipes with pipe or pipe.

working under the influence of thermal loads, and can find

wide application in the industry and energy industry.

The well-known flared joint of a pipe with a pipe is known, in which the end of the inner pipe from the end face is filled with an annular protrusion, and the outer pipe with a counter end groove with the formation of an end lock at the outlet section of the joint with a tapered junction. However, in this construction, an end lock is made only in one place and local decompression of the joint at the entrance of the joint is possible due to prolonged thermal effects when the connected elements are made of materials with different coefficients of temperature expansion.

Decompaction occurs due to the fact that with periodic heating to a certain

divided temperature or when cooled, the magnitudes of linear displacements in the radial direction of the grasping and covered elements are different. This is the reason for the occurrence in the area of the connection of forces and stresses that affect the opening of the contact point of the connected elements.

The proposed connection is characterized in that it is additionally provided with an end lock at the entrance of the connection, the outer pipe of which is made with an annular protrusion, and the internal one with an experienced ring groove, the transitional cone from this lock towards the connection facing the transitional cone of the lock.

The drawing shows the proposed compound, general view.

Claims (2)

  1. The sealed flared joint comprises an outer pipe 1 and an inner pipe 2. The end of the pipe 2 on the end 3 side is made with an annular protrusion 4, and the pipe 1 with a counter end groove 5 forms a lock 6 on the outlet section of connection 7. At the inlet section of the pipe 7 pipe 1 It also has an annular protrusion 8, and the pipe 2 has a second notch 9, that is, an additional lock 1O is formed. The transition cone 11 is located from the lock 6 to the connection 7, and the transition cone 12 from the lock 10 to the connection 7, with the cone 12 facing the cone 11. The materials of pipes 1 and 2 have different coefficients of temperature expansion. This connection is obtained as follows: Pipe 2 is filled with pipe 2, with the annular protrusion 4 of the pipe 2 entering the annular groove 5 of the pipe 1, and the protrusion 8 of the pipe 1 entering the groove 9 of the pipe 2. The matching surfaces of pipes 1 and 2 form compound 7 on transitional landing. The assembled structure is flared. With this design of the joint, and in any combination of thermal expansion coefficients of the elements of the joint 7, the annular protrusion 8 of the pipe 1 is an obstacle for the free movement of the pipe 2 with the counter ring groove 9 in the radial direction. In this case, the radial movement of one pipe is copied by the second pipe. This ensures that contact is maintained throughout the entire connection 7 of pipe 1 and
  2. 2. The Claims , in order to increase the tightness of the joint of pipes with different coefficients of temperature expansion with repeated thermal cycling action, it is additionally equipped with an end lock at the entrance of the joint , Outer pipe which is provided with KonbneBbnvi protrusion and the inner - mate with the annular groove, wherein the transition from the cone to the compound of this lock is directed towards the Transitional lock cone disposed at the outlet portion of the compound.
