  2. Natural gas pipeline system in the United States - Wikipedia

    en.wikipedia.org/wiki/Natural_gas_pipeline...

    Meanwhile, manufactured gas was more commonly used than natural gas in the early 19th century, first introduced in Baltimore in 1816 with underground pipes laid starting in 1851. [6] Gas plants could be sited within cities, and many major U.S. cities such as New York, Chicago, San Francisco had gas distribution lines for manufactured gas by the ...

  3. NEL pipeline - Wikipedia

    en.wikipedia.org/wiki/NEL_pipeline

    The diameter of the pipeline is 56 inches (1,400 mm) and it uses 100 bars (10,000 kPa) operating pressure. [3] Its capacity is 20 billion cubic metres (710 billion cubic feet) of natural gas per year.

  4. Gas meter - Wikipedia

    en.wikipedia.org/wiki/Gas_meter

    Both technologies involve transducers that are simply clamped on to the pipe and programmed with the pipe size and schedule and can be used to calculate flow. Such meters can be used to measure almost any dry gas including natural gas, nitrogen, compressed air, and steam. Clamp-on meters are available for measuring liquid flow as well.

  5. 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 ...

  6. Darcy friction factor formulae - Wikipedia

    en.wikipedia.org/wiki/Darcy_friction_factor_formulae

    The Reynolds number Re is taken to be Re = V D / ν, where V is the mean velocity of fluid flow, D is the pipe diameter, and where ν is the kinematic viscosity μ / ρ, with μ the fluid's Dynamic viscosity, and ρ the fluid's density. The pipe's relative roughness ε / D, where ε is the pipe's effective roughness height and D the pipe ...

  7. Pipe (fluid conveyance) - Wikipedia

    en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

    In Canada, with respect to natural gas (NG) and propane (LP gas), black iron pipe (BIP) is commonly used to connect an appliance to the supply. It must however be marked (either painted yellow or yellow banding attached at certain intervals) and certain restrictions apply to which nominal pipe size (NPS) can be put through walls and buildings.

    When 3D pipe stress is analyzed, it (3D Pipes) will be considered as 3D beams with supports on both sides. Moreover, the 3D pipe stress determines the bending moments of the pipes. Allowable (ASME) Pipe grades permitted for Oil and gas industries are : Carbon Steel Pipes and tubes (A53 Grade [A & B], A106 Grade [B & C]), Low & Intermediate ...

  9. Pipe drift - Wikipedia

    en.wikipedia.org/wiki/Pipe_drift

    Pipe drift is a measure of the roundness or eccentricity of the inside wall of a pipe. "API drift" refers to primary specifications set forth in API Specification 5CT ( ISO 11960), "Specification for Casing and Tubing".
