Transient simulation of vapor-liquid eruption and overpressure in the drainage terminal of an inclined pipeline during pigging process after water pressure test

Pigging technology is widely used in the oil and gas industry. During the course of pigging, after a water pressure test, the instability of the pig caused by terrain fluctuation can affect the stable operation of the pipeline and even cause burst accidents. This paper describes the four stages of p...
