Abstract
Systems and methods for creating a pressure pulse within a pipeline are disclosed. The method includes isolating a barrel of a pipeline inspection gauge (PIG) station from the pipeline, pressurizing the barrel up to a selected pressure, and opening an isolation valve between the barrel and the pipeline, thereby creating the pressure pulse.
Claims6
A method of creating a pressure pulse within a pipeline, comprising:
- isolating a barrel of a pipeline inspection gauge (PIG) station from the pipeline;
- pressurizing the barrel up to a selected pressure by:
- opening the barrel from the outside;
- inserting a pressure container with an embedded valve into the barrel;
- closing the barrel;
- and
- opening the embedded valve;
- and
- opening an isolation valve between the barrel and the pipeline, thereby creating the pressure pulse.
