Abstract
A method for manufacturing a pipe conduit arrangement including sticking a pipe stub onto a pipe conduit at least up to the flush state of the of the flange section end-face and the pipe conduit end-face, fixing the pipe conduit in the pipe stub in a press fit which is produced by the radial widening of the pipe conduit, and axially clamping the arisen pipe conduit units by way of clamping the flange sections of the pine stubs into the nine conduit arrangement. Also described is a pipe conduit arrangement.
Claims11
A method for manufacturing a pipe conduit arrangement comprising two pipe conduit units which have a pipe conduit middle axis, wherein each pipe conduit unit comprises a pipe conduit which has a pipe conduit outer surface, a pipe conduit end-face and a pipe conduit outer diameter, and a pipe stub which has a pipe stub inner diameter and which comprises a flange section and a pipe section, said flange section comprising a flange section end-face and said pipe section comprising a pipe section inner surface, and a seal which is arranged axially between the flange section end-faces of the pipe stubs, and a clamping device which axially clamps the flange sections of the pipe stubs of the two pipe conduit units to one another, the method comprising:
- forming each of the pipe conduit units, wherein forming each of the pipe conduit units comprises, for each of the pipe conduit units:
- sticking the pipe stub onto the pipe conduit at least up to a flush state of the flange section end-face and the pipe conduit end-face;
- and
- fixing the pipe conduit in the pipe stub in a press fit which is produced by the a radial widening of the pipe conduit;
- and
- axially clamping the formed pipe conduit units to one another by way of clamping the flange sections of the respective pipe stubs into the pipe conduit arrangement,
- wherein the seal comprises a seal insert and after the clamping of the formed pipe conduit units into the pipe conduit arrangement, the seal forms a transition between the pipe conduit units which are clamped to one another, and
- wherein the transition is defined by pressing forces which are set by the seal insert such that an arching with respect to a pipe conduit inner diameter forms an obtuse angle.
A pipe conduit arrangement, comprising:
- two pipe conduit units which have a pipe conduit middle axis, wherein each pipe conduit unit comprises:
- a pipe conduit which has a pipe conduit outer surface, a pipe conduit end-face, and a pipe conduit outer diameter;
- and
- a pipe stub which has a pipe stub inner diameter and which comprises a flange section and a pipe section, said flange section having a flange section end-face and said pipe section having a pipe section inner surface;
- a seal which is arranged axially between the flange section end-faces of the pipe stubs;
- and
- a clamping device which axially clamps the flange sections of the pipe stubs of the two pipe conduit units to one another,
- wherein, for each pipe conduit unit, the pipe stub is stuck onto the pipe conduit at least up to the flush state of the flange section end-face and the pipe conduit end-face,
- wherein, for each pipe conduit unit, the pipe conduit is fixed in the pipe stub in a press fit which is produced by the radial widening of the pipe conduit,
- wherein the seal comprises a seal insert and after the clamping of the formed pipe conduit units into the pipe conduit arrangement, the seal forms a transition between the pipe conduit units which are clamped to one another, and
- wherein the transition is defined by pressing forces which are set by the seal insert such that an arching with respect to a pipe conduit inner diameter forms an obtuse angle.
