Types of Pipeline Pigs
There are several types of pipeline pigs used in the oil and gas industry:
1. Cleaning Pigs: These remove debris, dirt, and other contaminants from the pipeline walls.
2. Gauging Pigs: Used to measure the internal diameter and check for deformities or obstructions.
3. Brush Pigs: Equipped with brushes to scrape off rust, scale, or other deposits from the pipeline's interior.
4. Foam Pigs: Made of foam material and used for cleaning and separation of different product batches in multiproduct pipelines.
5. Smart Pigs (ILI tools): In-line inspection pigs equipped with sensors and technology to assess pipeline integrity, detect defects, and gather data.
6. Magnetic Pigs: Used to identify and remove ferrous debris or corrosion by utilizing magnetic
attraction.
7. Utility Pigs: Designed for specific tasks like drying pipelines, hydrostatic testing, or applying corrosion inhibitors.
8. Bi-Di Pigs: Used for bi-directional pipeline cleaning and inspection.
9. Spheres: Hollow metal or plastic spheres are used for liquid batching and product separation.
10. Pig Traps: Devices used to launch and receive pigs safely into and out of pipelines.
These pigs serve various purposes in maintaining pipeline functionality, ensuring safety, and maximizing efficiency.
