pig PArts and their uses
Discs: Are effective at pushing out solids and providing a good support for the pig.
Conical Cups: Provide excellent sealing characteristics, good support and long wear.
Bypass Ports: These allow some of the flow to bypass through the pig and help minimize solid build up at the front of the pig.
Spring Mounted Brushes: Provide a continuous forceful scraping for removal of rust, scale and other build ups on the wall of the pipe.
Circular Brushes: The brushes are bi-directional and can be stacked for scraping for removal of rust, scale and build-ups.
Pit Boss/Pencil Brush: Scrapes deep into pits to remove build-ups.
Gauge Plate: For discovery of deformities/obstructions in the line, also commonly used prior to ILI runs.
Magnets: Pick up ferrous materials and give indications to loose debris in the line.

TDW PIGGING INSIGHTS - Episode 3
Instructions for the preparation and filling of TDW Unisphere Pigs
TDW Unisphere Pig
TDW Unisphere pigs are seamless liquid cast polyurethane balls. They are designed for removal of liquid hydrocarbons and water as well as batch separation for pipelines handling different liquids. Unisphere pigs are hollow, they can be filled with liquid and also be inflated with pressure to match the pipeline’s ID.
Preparation for Use
Unispheres must be filled with liquid before use. Water/glycol or light lube oil solutions are recommended. It is best to avoid using pure glycol as a filling solution. The 4 inch to 8 inch Unispheres have one filling valve. Larger spheres have two valves; either valve can be used. Other components required are an inflating valve, valve core, pipe plug, filling adapter and valve core extractor.
Filling Procedure (not including inflating with pressure)
1. Remove inflating valve with a 3/8 in Allen wrench.
2. Fill sphere with liquid using funnel or hose.
3. The opening must be at the top and sphere completely filled with air displaced. Rolling the sphere slightly around can help to settle liquid and displace air.
4. Inspect O-Ring on inflating valve for nicks and burrs, and replace if necessary. Apply lubricant to O Ring and threads.
5. Remove pipe plug, and check the tightness of valve. A valve core extractor is available.
6. Install inflating valve and tighten securely.
