    Clean-in-place (CIP) is an automated method of cleaning the interior surfaces of pipes, vessels, equipment, filters and associated fittings, without major disassembly. CIP is commonly used for equipment such as piping, tanks, and fillers. CIP employs turbulent flow through piping, and/or spray balls for tanks or vessels.

    en.wikipedia.org/wiki/Tube_cleaning

    Chemical tube cleaning is understood to be the use of cleaning liquids or chemicals for removing layers and deposits. A typical example is the deliming of a coffee maker where scale is removed by means of acetic acid or citric acid. Depending on the field of application and tube material, special cleaning liquids may be used which also require ...

  4. Pipeline pre-commissioning - Wikipedia

    en.wikipedia.org/wiki/Pipeline_pre-commissioning

    Pipeline Filling (Flooding) – which can be carried out by propelling pigs through the pipeline with water or free flooding with water (normally for smaller or unpiggable pipelines). Hydrotesting – this is a process by which the pipeline in question is pressure tested to a predefined pressure above the operating design pressure of the pipeline.

    Cleaning can also be simple: the cleaning processes are integrated into other processes, as it is the case with electroplating or galvanising, where it usually serves as a pre-treatment step. The following procedure is quite common: Pre-cleaning; Main cleaning; Rinsing; Rinsing with deionised water; Rinsing with corrosion protection; Drying

  6. Pigging - Wikipedia

    en.wikipedia.org/wiki/Pigging

    A cleaning pig for a 710-millimetre (28 in) oil pipeline. The blue plastic disks seal against the inside of the pipe to propel the device and to remove loose sedimentation or scale buildup. The black rectangles at the top and the circular disks in the center are magnets to attract and remove any loose metal objects in the pipe.

    It is a jointless, seamless pipe lining within an existing pipe. As one of the most widely used rehabilitation methods, CIPP has applications in sewer, water, gas, chemical and district heating pipelines ranging in diameter from 0.1 to 2.8 meters (2–110 inches).

  9. Ice pigging - Wikipedia

    en.wikipedia.org/wiki/Ice_Pigging

    Ice pigging is a technique used for cleaning pipes, distinguished from traditional pigging by the use of a semi-solid 'pig' made of ice, rather than a solid object. This ice pig is capable of flowing through pipes, navigating obstructions such as valves and variations in pipe diameter, due to its fluid-like properties.
