摘要： Tubes for use in ultrahigh pressure devices, and associated systems and methods of manufacture are disclosed herein. In one embodiment, a metal tube includes an elongate bore having a circular transverse cross-sectional shape. The metal tube also includes an elongate wall extending around the bore and having an annular transverse cross-sectional shape with an inner surface closest to the bore, an outer surface furthest from the bore, and a wall thickness extending from the inner surface to the outer surface. An inner portion of the wall is under swage-autofrettage-induced overall compressive stress.

摘要： Automatically controlled adjustable dump orifices (ADO) for use with liquid jet cutting systems are disclosed herein. In some embodiments, the automatically controlled ADOs described herein include a motor (e.g., an electric motor) and a coupling configured to operably couple the motor to a valve. The valve is configured to cooperate with a dump orifice connected in fluid communication with a high-pressure pump of the cutting system. The motor is operable to move the valve in a first direction to increase the pressure of high-pressure liquid (e.g., water) flowing through the dump orifice and in a second direction, opposite to the first direction, to reduce the pressure of the high-pressure liquid flowing through the dump orifice.
