  2. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.

  3. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    Methods of detection include hydrostatic testing, tracer-gas leak testing, infrared, laser technology, and acoustic or sonar technologies. Some technologies are used only during initial pipeline installation and commissioning, while other technologies can be used for continuous monitoring during service.

  4. Pipeline pre-commissioning - Wikipedia

    en.wikipedia.org/wiki/Pipeline_pre-commissioning

    Other services include vacuum drying, degassing, pneumatic testing, barrier testing, leak testing, decommissioning to mention but a few. On the pipeline process pre-commissioning side, there are various services such as chemical cleaning, helium leak detection, bolting, hot oil flushing, pipe freezing, foam inerting etc...

  5. Piping and plumbing fitting - Wikipedia

    en.wikipedia.org/wiki/Piping_and_plumbing_fitting

    The bodies of fittings for pipe and tubing are often the same base material as the pipe or tubing connected: copper, steel, PVC, CPVC, or ABS. Any material permitted by the plumbing, health, or building code (as applicable) may be used, but it must be compatible with the other materials in the system, the fluids being transported, and the ...

  6. Pigging - Wikipedia

    en.wikipedia.org/wiki/Pigging

    This is done by using a triple-plate capacitive sensor in which electrostatic waves are propagated outward through the pipe's wall. Any change in dielectric material results in a change in capacitance. [17] Testing was conducted by NETL DOE research lab at the Battelle West Jefferson's Pipeline Simulation Facility (PSF) near Columbus, Ohio. [18]

  7. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  8. Proof test - Wikipedia

    en.wikipedia.org/wiki/Proof_test

    A proof test is a form of stress test to demonstrate the fitness of a load-bearing or impact-experiencing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above those expected in actual use, demonstrating safety and design margin.

  9. Pipe plug - Wikipedia

    en.wikipedia.org/wiki/Pipe_plug

    A pipe plug is a tool or material for the temporary sealing of pipelines in sewerage and other liquid and gas transportation systems; typically for maintenance or non-pressurized line testing. A pipe plug is also known as an inflatable plug, [1] mechanical pipe plug, [2] pipe test plug, pipeline isolation plug, expandable plug, pipe bung, pipe ...
