Heavy-duty and designed for aggressive cleaning, Pencil Brush pigs work to rid pipelines of finely divided black powder and hard scale deposits, including magnetic scale. That makes them ideal for pre-inline inspection (ILI) cleaning, which is essential to improving run result accuracy.
Each pig is equipped with multiple brushes made of high tensile steel or posistrand filament, which help maintain cleaning efficiency even when the pig travels long distances. Brushes are made to conform to the inside diameter of the pipe and provide 100 percent circumferential cleaning in pipelines ranging in size from 4 inches through 42 inches. Removable bypass plugs provide a jetting action that further improves cleaning effectiveness.
