    ROHR2 is a CAE system for pipe stress analysis from SIGMA Ingenieurgesellschaft mbH, based in Unna, Germany. The software performs both static and dynamic analysis of complex piping and skeletal structures, and runs on Microsoft Windows platform. [1] [2]

  3. Surge control - Wikipedia

    en.wikipedia.org/wiki/Surge_control

    Surge control products have been used in many industries to protect the maximum working pressure of hydraulic system for decades. Typical applications for surge relief equipment is in pipelines at pump stations, receiving manifolds at storage facilities, back pressure control, marine loading/off loading, site specific applications where pressure surges are generated by the automation system ...

  4. Water hammer - Wikipedia

    en.wikipedia.org/wiki/Water_hammer

    Effect of a pressure surge on a float gauge. Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly: a momentum change.

  5. Hardy Cross method - Wikipedia

    en.wikipedia.org/wiki/Hardy_Cross_method

    The Hardy Cross method can be used to calculate the flow distribution in a pipe network. Consider the example of a simple pipe flow network shown at the right. For this example, the in and out flows will be 10 liters per second. We will consider n to be 2, and the head loss per unit flow r, and initial flow guess for each pipe as follows:

  6. MPDS4 - Wikipedia

    en.wikipedia.org/wiki/MPDS4

    MPDS4 PIPING DESIGN is an industrial piping design software add-on with extensive libraries of catalogue components to a variety of industrial standards, including DIN, ANSI and BS. Its routing tools are used for loading, positioning and replacing components, manually or automatically.

  7. Pipe network analysis - Wikipedia

    en.wikipedia.org/wiki/Pipe_network_analysis

    In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.
