a perforating process involving pumping a slurry of liquid and size particles through a nozzle to cut through steel and rock.

n: The pressure within a system caused by fluid friction or an induced resistance to flow through the system. Hydraulic Thru-Tubing Fishing tools are typically operated using back pressure created by fiow through a nozzle.

a pressure caused by a restriction or fluid head that exerts an opposing pressure to flow.

n: the measure of hydraulic power expended through the bit nozzles for cleaning the bit cutters and the hole bottom.

n: see nozzle.

n: Refers to the drilling fluid gun whose nozzle is installed in the bottom of drilling fluid tin.

n: in pipeline construction, a pipestraddling device, fitted with nozzles, spoil from beneath the pipe is removed and pumped to one side of the trench. The line then sages naturally into position in the trench.

n: trade name for appratus for cleaning and freeing oil tanks of gas by means of high-pressure jets of hot water. It consistes essentially of opposed double nozzles, which rotate slowly about their horizontal and vertical axes and project two streams of hot water at a pressure of 175 psi (1,206 kilo pascals) against all inside surfaces of the deck, bulkheads, and shell plating.

n: The pressure of fluid decreases below saturated vapor pressure and forms jet with numbers of air bubble when the fluid passes through special nozzle. The air bubble forms domestic high pressure when striking the solid border.

n: a fishing tool that uses high-pressure jets of chemicals to sever casing, tubing, or drill pipe stuck in the hole.

n: The cutting tool with ejecting opening in the bottom.

a pipe cutting tool that uses boron trifluoride sprayed through a nozzle at very high velocities.
