The operator of a major oil transmission line in the Central Rockies was pigging a 16-mile (25.7-km), 12-in. (30.5 cm) diameter section of pipeline weekly, primarily to remove paraffin buildup. During each pigging operation, the cumulative mass of paraffin delivered to the pig receiver would plug the line, causing it to overpressure to the point of bursting the rupture disk.
