Abstract: This article shows the results of such a study, which has been triggered by a technological incident: the wrenching from the compensator and its axial shifting of a large diameter air pipe in a wastewater treatment plant, event that occurred after many years of normal operating. The phenomenon that occurred can be justified only as a result of action of some axial forces, taking into account that axial shifting of rectilinear pipe sectors is not impeded by any special blocking device, but only by the friction of the pipe on its supports (axially) and by the resistance torque generated by its own weight (in the supports of the perpendicular sectors). The friction forces on supports correspond to the total weight of the studied pipe (length and number of flanged couplings) and to the friction factor between pipes and supports. The axial forces that act upon bends correspond to the action's direction is sensibly depending of friction factor between mains and supports.!
The vertical force on the supports V corresponds to the quasi-even distribution of the total weight of the free shifting sector, on the nr supports that exist on its route. Deformation occurring in the console pipe sector allows an axial shifting of the perpendicular sector, corresponding to the arrow in its free end f.
