Pre-sweep pipeline to remove debris from the line. Use a 5lb poly pig such as a Bullet-Nose Poly Pig, or a Wire Brush Poly Pig.
Run a Gauge Pig with sizing plate to check for dents and ocalities. We recommend a Multi-Disc Bi Directional Steel Mandrel Pig.
Fill the pipeline using a bidirectional pig, such as a Double-Dished Poly Pig or a Foam Disc Poly Pig. This will allow one to utilize the same pig for Dewater Operations.
When clean and dry operations require a 1/4" Dust Penetration and Dew Point, a series of Total-Wire Brush Pigs and Bare Foam Swabs are required. For best results use a descant dryer in your air spread.
