Dynamics of pig motion in gas pipelines
WebMar 1, 2016 · Most pigging operations in gas pipelines are performed at normal operating pressures with regular flow rates, and the PIG velocity is generally in the range of 2–5 m/s. However, pigging in low-pressure and low-flowrate gas pipelines is very difficult due to speed excursion, which rapidly increases the PIG velocity. WebThe next graph shows the velocity against time output for both the normal bypass pig and the VC Pig (Velocity Control Pig), with both pigs having a drive Differential of 1.1bars in the first section of pipe. This shows that a …
