Speed Simulation of Pig Restarting from Stoppage in Gas Pipeline

Figure 7

Parametric sensitivity analysis of pig restarting from a stoppage by increasing upstream pressure. (a) Change of pig mass, (b) change of pipe diameter, (c) change of the stuck position, (d) change of pipe length, (e) change of obstruction force, and (f) change of gas pressure.
