Abstract EN
The pipeline inspection gauge (PIG, lowercase pig is commonly used) with a bypass valve is widely used in pipeline inspection because it operates at a low speed without reducing the flow rate.
Understanding the dynamics of a bypass pig in a gas pipeline would contribute to the design of the pig and the control of pig speed.
This paper deals with the dynamic model for the process of a bypass pig travelling through a hilly gas pipeline.
The method of characteristics (MOC) is used to solve the equations of unsteady gas flow.
The backward flow of the gas in the bypass valve and pipe is shown by a simulation of pigging for a hilly gas pipeline.
Parametric sensitivity analysis of pigging in the horizontal gas pipe using a bypass pig is then carried out.
The results indicate that the speed of a bypass pig is most sensitive to the gas speed in the pipe followed by the bypass area and the friction of the pig.
A formula, obtained from the results of the simulations using response surface methodology (RSM), is presented to predict the steady speed of a bypass pig in the horizontal gas pipeline.
