  2. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    A stream of oxygen is then trained on the metal, burning it into a metal oxide that flows out of the kerf as dross. [5] Torches that do not mix fuel with oxygen (combining, instead, atmospheric air) are not considered oxy-fuel torches and can typically be identified by a single tank (oxy-fuel cutting requires two isolated supplies, fuel and ...

  3. Oxygen compatibility - Wikipedia

    en.wikipedia.org/wiki/Oxygen_compatibility

    In an oxygen system the presence of oxygen is implied, and in a sufficiently high partial pressure of oxygen, most materials can be considered fuel. Potential ignition sources are present in almost all oxygen systems, but fire hazards can be mitigated by controlling the risk factors associated with the oxygen, fuel, or heat, which can limit the ...

  4. Air-line fitting - Wikipedia

    en.wikipedia.org/wiki/Air-line_fitting

    Pneumatic tool attached using a coupling. A coupled pair consists of a male nipple or plug and a female coupler or socket.One side is connected to a flexible supply hose; the other may be attached to a manifold, valve, tool, or another hose.

    A MIL-DTL-38999 circular connector plated with a nickel–teflon composite. Left: plug (male) type connector; Right: receptacle (female) type connector) Electrical or fiber-optic connectors used by U.S. Department of Defense were originally developed in the 1930s for severe aeronautical and tactical service applications, and the Type "AN" series set the standard for modern military circular ...

  6. Air gun - Wikipedia

    en.wikipedia.org/wiki/Air_gun

    A para-athlete competing with a match air rifle A collection of lever-action, spring-piston air rifles. An air gun or airgun is a gun that uses energy from compressed air or other gases that are mechanically pressurized and then released to propel and accelerate projectiles, similar to the principle of the primitive blowgun.

  7. Electro-galvanic oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Electro-galvanic_oxygen_sensor

    Electro-galvanic fuel cell as used in a diving rebreather to measure the partial pressure of oxygen. Two oxygen cells as used by oxygen analysers for diving gas showing commonly used connectors. An electro-galvanic fuel cell is an electrochemical device which consumes a fuel to produce an electrical output by a chemical reaction.

  8. Pin Index Safety System - Wikipedia

    en.wikipedia.org/wiki/Pin_Index_Safety_System

    The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated with the gas mixture, which prevent connection of the cylinder to a yoke or pressure regulator with a mis-matched set of pins.

  9. Quick connect fitting - Wikipedia

    en.wikipedia.org/wiki/Quick_connect_fitting

    Pneumatic couplings are specialized quick connect fittings used for compressed air and gas applications. These couplings allow for fast and secure connections, ensuring efficiency and safety in pneumatic systems. They are designed to minimize pressure drops, prevent air leakage, and provide durability under high-pressure conditions.
