Abstract (en)
The present invention relates to a tube (100) for being installed into a guide vane (120) of a turbine. The tube (100) comprises a tube wall (101) for forming a fluid channel and a dividing wall (110) which is arranged inside the fluid channel. The dividing wall (110) comprises a first edge (111) and a second edge (112) which is spaced apart from the first edge (111). The first edge (111) is fixed to a first surface section of the tube wall (101). The dividing wall (110) is formed in such a way that the second edge (112) resiliently abuts in a detachable manner against a second surface section of the tube wall (101) such that the dividing wall (110) divides the fluid channel in a first channel (I) and a second channel (II).
