  2. Gas networks simulation - Wikipedia

    en.wikipedia.org/wiki/Gas_networks_simulation

    Gas networks simulation or gas pipeline simulation is a process of defining the mathematical model of gas transmission and gas distribution systems, which are usually composed of highly integrated pipe networks operating over a wide range of pressures. Simulation allows to predict the behaviour of gas network systems under different conditions ...

  3. Maximum allowable operating pressure - Wikipedia

    en.wikipedia.org/wiki/Maximum_allowable...

    Maximum Allowable Operating Pressure (MAOP) is a pressure limit set, usually by a government body, which applies to compressed gas pressure vessels, pipelines, and storage tanks. For pipelines, this value is derived from Barlow's Formula , which takes into account wall thickness, diameter, allowable stress (which is a function of the material ...

  4. Nominal Pipe Size - Wikipedia

    en.wikipedia.org/wiki/Nominal_Pipe_Size

    Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...

  5. Barlow's formula - Wikipedia

    en.wikipedia.org/wiki/Barlow's_formula

    Barlow's formula (called "Kesselformel" [1] in German) relates the internal pressure that a pipe [2] can withstand to its dimensions and the strength of its material.This approximate formula is named after Peter Barlow, an English mathematician.
