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.

Motorized systems and associated methods for controlling an adjustable dump orifice on a liquid jet cutting system

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.

Mechanical processing of high aspect ratio metallic tubing and related technology

Particle-delivery devices, abrasive jet systems, and associated devices, systems, and methods are disclosed herein. In certain aspects, the particle-delivery devices can include an elongated fluidizing chamber and a metering assembly. The metering assembly can include a particle flow path extending from the fluidizing chamber. The metering assembly can also include a carrier-gas passage extending to an injection orifice proximate the fluidizing chamber. The metering assembly can be configured to inject carrier gas into the fluidizing chamber to fluidize particles within the fluidizing chamber. Fluidizing the particles at different carrier-gas pressures and/or flow rates can change the rate of particle delivery. For example, the metering assembly can include a metering opening and a regulator configured to change a steady-state pressure and/or flow rate of carrier gas entering the fluidizing chamber. Systems disclosed herein can include a controller configured to change a flow rate of particles through the metering opening.
