PRESSURIZED FLUID PIPE |
摘要 |
A pipe for pressurised-fluid feed systems, such as a diesel engine fuel pipe, has a wall of predetermined thickness with an internal surface and an external surface and an internal bore with a predetermined diameter for through-flow of the fluid. The internal surface and/or external surface are subjected to a nitriding or carbonitriding treatment, so as to obtain an increase in the hardness and/or the mechanical strength of the pipe, with regard to both stresses due to the pressure of the fluid and axial stresses due to flexing of the pipe.
