    en.wikipedia.org/wiki/Pigging

    There is no requirement for extensive line flushing. Without the need for line flushing, pigging offers the additional advantage of much more rapid and reliable product changeover. Product sampling at the receipt point is faster with pigs, because the interface between products is very clear; the old method of checking at intervals to determine ...

    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.

    For piping built to ASME B31.3, if the design temperature is greater than the test temperature, then the test pressure must be adjusted for the related allowable stress at the design temperature. This is done by multiplying 1.5 MAWP by the ratio of the allowable stress at the test temperature to allowable stress at the design temperature per ...
