  2. 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 ...

  3. Gas networks simulation - Wikipedia

    en.wikipedia.org/wiki/Gas_networks_simulation

    A gas network is in the steady state when the values of gas flow characteristics are independent of time and system described by the set of nonlinear equations. The goal of simple simulation of a gas network is usually that of computing the values of nodes' pressures, loads and the values of flows in the individual pipes.

  4. Barlow's formula - Wikipedia

    en.wikipedia.org/wiki/Barlow's_formula

    The formula is also common in the pipeline industry to verify that pipe used for gathering, transmission, and distribution lines can safely withstand operating pressures. The design factor is multiplied by the resulting pressure which gives the maximum operating pressure (MAOP) for the pipeline.

  5. OLGA (technology) - Wikipedia

    en.wikipedia.org/wiki/OLGA_(technology)

    The name is short for "oil and gas simulator". The main challenge with multiphase fluid flow is the formation of slugs (plugs of oil and water) in the pipelines, which causes large problems at the receiving end at the platform or the onshore plant.

  6. Petroleum transport - Wikipedia

    en.wikipedia.org/wiki/Petroleum_transport

    The Trans-Alaska Pipeline System cuts through Alaska's wilderness. Special heat exchanger supports protect the Permafrost from melting. Pipelines are used to transport oil from wells to refineries and storage facilities, and are viewed as the most cost efficient way to move oil on land. [3]

  7. Specified minimum yield strength - Wikipedia

    en.wikipedia.org/wiki/Specified_Minimum_Yield...

    It is an indication of the minimum stress a pipe may experience that will cause plastic (permanent) deformation. The SMYS is required to determine the maximum allowable operating pressure (MAOP) of a pipeline, as determined by Barlow's Formula which is P = (2 * S * T)/(OD * SF), where P is pressure, OD is the pipe’s outside diameter, S is the ...

  9. Moody chart - Wikipedia

    en.wikipedia.org/wiki/Moody_chart

    where is the density of the fluid, is the average velocity in the pipe, is the friction factor from the Moody chart, is the length of the pipe and is the pipe diameter. The chart plots Darcy–Weisbach friction factor f D {\displaystyle f_{D}} against Reynolds number Re for a variety of relative roughnesses, the ratio of the mean height of ...
