  2. Pipe bursting - Wikipedia

    en.wikipedia.org/wiki/Pipe_bursting

    A machine is set in the receiving pit to pull the expander head and new pipe into the line. The head is pulled by heavy, interlocking links that form a chain. Each link weighs several hundred pounds. All of the equipment used in a pipe bursting operation is powered by one or multiple hydraulic power generators.

  3. Pipe recovery operations - Wikipedia

    en.wikipedia.org/wiki/Pipe_recovery_operations

    Pipe Stretch Free Point Estimate. The pipe stretch free point estimate is a good starting point for identifying the free point. Pull the drillstring to the pipe's neutral weight, which is the combined weight of blocks and the weight of the drill string and make a mark(X 1)(in) at the top of the rotary table.

  4. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then revalidated at regular intervals according to the relevant standard.

  5. Rupture disc - Wikipedia

    en.wikipedia.org/wiki/Rupture_disc

    A rupture disc (burst) Pressure-effect acting at a rupture disc A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.

  6. Fault detection and isolation - Wikipedia

    en.wikipedia.org/wiki/Fault_detection_and_isolation

    For a rotating machine, the rotational speed of the machine (often known as the RPM), is not a constant, especially not during the start-up and shutdown stages of the machine. Even if the machine is running in the steady state, the rotational speed will vary around a steady-state mean value, and this variation depends on load and other factors.

  7. Pipe network analysis - Wikipedia

    en.wikipedia.org/wiki/Pipe_network_analysis

    Once the friction factors of the pipes are obtained (or calculated from pipe friction laws such as the Darcy-Weisbach equation), we can consider how to calculate the flow rates and head losses on the network. Generally the head losses (potential differences) at each node are neglected, and a solution is sought for the steady-state flows on the ...

  8. Magnetic flux leakage - Wikipedia

    en.wikipedia.org/wiki/Magnetic_flux_leakage

    MFL-ILIs detect and assess areas where the pipe wall may be damaged by corrosion. The more advanced versions are referred to as "high-resolution" due to their increased number of sensors. The high-resolution MFL-ILIs allow more reliable and accurate identification of anomalies in a pipeline, thus, minimizing the need for expensive verification ...

  9. Pipeline Pilot - Wikipedia

    en.wikipedia.org/wiki/Pipeline_pilot

    Pipeline Pilot was initially developed by SciTegic, a company that was acquired by BIOVIA in 2004. In 2014, BIOVIA became part of Dassault Systèmes.. Originally designed for applications in chemistry, Pipeline Pilot's capabilities have since been expanded to support a wider range of data processing tasks, including extract, transform, and load (ETL) processes, as well as general analytical ...
