Abstract
The invention relates to a process for connecting a pipe (2, 31) in the region of its pipe end to a pipe coupling (1), comprising at least one support sleeve (3) with engagement elements (5, 65, 67, 124), in which context the pipe (2, 31) and the support sleeve (3) are first pushed into one another, the pipe (2, 31) then being pressure deformed, thereby bringing about a form-fitting connection with the engagement elements (5, 65, 67, 125) and bringing about a sealing relationship with sealing surfaces (7, 66, 68, 122), mutually adjoining each other in axial direction. The process is characterised in that an axial force, bearing on the sealing surfaces (7, 66, 68, 122) is applied to the pipe (2, 31) by way of a spring device (20, 52) deriving support from the pipe coupling (1) and that a facility for expansion is provided for the pipe (2, 31) on the side of the engagement elements (5, 65, 67, 125) oriented towards the pipe.
