Abstract (en)
[origin: EP0341429A1] In such a device, there are difficulties when the axes of sleeve (7) and steam generator pipe (3) do not align. There are also problems with positioning the sleeve (7) exactly in its end position. To bring about accurate centring and positioning of the sleeve (7), it is envisaged that a lead-in (39) is formed by a connecting sleeve (40) which is supported resiliently in the axial direction. The sleeve (7) is clamped between a shoulder (18) of a holding grip (16) and a centring piece (17) which is variable in its external diameter. In this connection, the greatest diameter of the shoulder surface is smaller than the internal diameter of the connecting sleeve (40). The holding grip (16) is assigned a further shoulder (48), the axial distance of which from the first shoulder (18) is further away from the pipe bottom (1) than the first shoulder (18), by the height dimension of the connecting sleeve (40). The shoulder surface of the shoulder (48) comes to bear against an end surface of the connecting sleeve (40) which faces away from the pipe bottom (1), while an end surface of the connecting sleeve (40) which faces towards the pipe bottom (1) makes contact with it. <IMAGE>
