Abstract (en)
[origin: WO2016124660A1] A method for manufacturing a common rail (12) adapted to be arranged in a fuel injection system, the common rail (12) having a body (18) provided with a bore (28) defining an internal volume (V), said body (18) extending along a main axis (X) from a first extremity (22) having a first threaded female recess (30) to, a second extremity (26) having a second threaded female recess (44), the bore (28) opening at both ends in one of the recesses (30, 44), the method (100) comprising the steps of a first autofrettage step (130) of said bore (28), an autofrettage fluid (AF) being pressurized to a first pressure (PI) in the bore (28) during this first step (130) and, second autofrettage step (140) for treating the first female threaded recess (30), the autofrettage fluid (AF) being pressurized to a second pressure (P2) in the first recess (30) during this second step (140).
