To achieve a flange-like connection, a fertilizer body is used / one end of which has a surface and the other end is conical in shape to fit into the collar located on the pipe and if it slips out of the connection, it must be comparatively broad; In practice, the angle between the inner conical surface of the collar and the pipe axis is usually 37 ° or 45 ° that an exact axial adjustment of the coupling body is difficult to achieve * to solve this problem one has provided the facing to the pipe end of the Verbindüngskcrpers with an external thread, onto which a provided with a shoulder nut is screwed, and between ü'äi shoulder of the nut and the collar is a guide bushing with a relatively large

To eliminate the relatively large dimensional tolerance of the pipe and to ensure that the insert is held in place, the axial part protruding into the pipe end is preferably provided with a deformable annular recess or the like.

Summary,

The invention relates to a flange connection where at least one pipe end to be connected with is provided with a collar. In order to achieve an exact axial adjustment, a collar is inserted into the Tube end insertable insert used, which has a conical portion for abutment against the inner surface of the collar and an axially running control part which extends into the pipe end. The clamping flange of the connection is raised on to lie against the outside of the collar either directly or by means of an intermediate piece.
