2. Shut-off nozzle - Wikipedia

   en.wikipedia.org/wiki/Shut-off_nozzle

   Bolt Shut-off Nozzle type BHP - pneumatic or hydraulic actuation. A shut-off bolt, positioned perpendicular to the melt channel moves up and down according to actuation, and thus shuts off/opens the melt flow. This nozzle type has a single melt channel. It therefore does not require rerouting of the melt around the shut-off mechanism.

   Applied using eductor or compressed air foam system (CAFS) and pumped through fire hose to a foam nozzle (or sometimes a less-effective fog nozzle). Attack hose (Attack line) A use classification of a fire fighting hose connected to output of a pump or other pressure source (e.g., gravity). Fire hose used to apply water or other fire fighting ...

4. High-integrity pressure protection system - Wikipedia

   en.wikipedia.org/wiki/High-integrity_pressure...

   A high-integrity pressure protection system (HIPPS) is a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure before the design pressure of the system is exceeded, thus preventing loss of containment through ...

5. Nozzle - Wikipedia

   Convergent nozzles accelerate subsonic fluids. If the nozzle pressure ratio is high enough, then the flow will reach sonic velocity at the narrowest point (i.e. the nozzle throat). In this situation, the nozzle is said to be choked. Increasing the nozzle pressure ratio further will not increase the throat Mach number above one.

   While the hose is under pressure, it is inspected for leaks and to determine that the couplings are firmly attached. After testing the hose is drained, dried, rolled, and shipped to the customer. [17] Quality control. In addition to the final pressure testing, each hose is subjected to a variety of inspections and tests at each stage of ...

7. Fog nozzle - Wikipedia

   en.wikipedia.org/wiki/Fog_nozzle

   A fog nozzle. A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small droplets.By doing so, its stream achieves a greater surface area, and thus a greater rate of heat absorption, which, when compared to that of a smoothbore nozzle, speeds its transformation into the steam that smothers the fire by displacing its oxygen.
