... brush cleaning pigs through pipelines will remove accumulated solid debris as well as smoothen the pipe wall. This will reduce pipeline pressure as well as increase product flow. A pig with sealing discs will push out accumulated condensates in gas pipelines and will prevent internal corrosion...

Paper No: IPC2012-90354
... With the method of characteristic (MOC) and analysis for the dynamic state of trapped air, this study could be performed on the basic theory of gas-liquid two phase unsteady flow, and cavitation and bubble dynamics, to obtain the overpressure value during pigging. For a long slope pipeline...
