  2. Pressure washing - Wikipedia

    en.wikipedia.org/wiki/Pressure_washing

    High-pressure water jetting, also called hydrojetting, is a variation in which the pressure can be significantly higher (up to 1,400 bars (20,000 psi)) than consumer models, and is sufficiently hazardous that special precautions are necessary for acceptable safety. High-pressure water jetting also has applications in cutting a wide range of ...

    Robotic Hydrodemolition in Folkestone, UK. Hydrodemolition of concrete exposing the rebar.. Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, waterblasting, and waterjetting) is a concrete removal technique which utilizes high-pressure water, often containing an abrasive material, to remove deteriorated and sound concrete as well as asphalt and grout.

  4. High pressure jet - Wikipedia

    en.wikipedia.org/wiki/High_pressure_jet

    Contour animation of the mole fraction variation (from 0.025 to 0.05) of a Natural Gas jet as it impinges a steel tank done through CFD.. A high pressure jet is a stream of pressurized fluid that is released from an environment at a significantly higher pressure than ambient pressure from a nozzle or orifice, due to operational or accidental release.

  5. In-water surface cleaning - Wikipedia

    en.wikipedia.org/wiki/In-water_surface_cleaning

    Water jetting. High pressure water jetting – when correctly applied, high pressure water jetting can provide acceptable levels of cleaning without damaging anti-fouling coatings or releasing toxins to the environment, but this requires fairly accurate control of jet angle and distance from the surface, and duration of impingement. In other ...

    The main difference between the two is the pressure and flow. High pressure removal uses water at 2,000–15,000 psi (14,000–103,000 kPa) at up to 30 US gallons per minute (1.9 L/s) while ultra high pressure removal uses up to 40,000 psi (280,000 kPa) with a water usage between 8 and 16 US gallons per minute (0.50 and 1.01 L/s) (Speidel, 2002 ...
