How Many Types Do You Know About Pipeline Cleaning Pigs?

Here is a brief introduction to the different types of piping pigs provided by EMT (or commonly found in pipeline maintenance and cleaning operations):

1. Solid Cast Pigs

• Description: Made from polyurethane or other durable material.
• Use: Ideal for cleaning, batching, and gauging.
• Características: No moving parts, resistant to wear and corrosion, can handle moderate debris.

2. ABS Pigs

• Description: Pigs with Acrylonitrile Butadiene Styrene (ABS) components, often used in combination with other materials.
• Use: Suitable for general cleaning and inspection preparation.
• Características: Lightweight, impact-resistant, and cost-effective.

3. Cup Pigs

• Description: Feature flexible cups (usually polyurethane) that form seals against the pipe wall.
• Use: Used for cleaning, liquid removal, and separation.
• Características: Multiple cups can be added for better sealing and scraping ability.

4. Disc Pigs

• Description: Similar to cup pigs but use flat or concave discs instead of cups.
• Use: Excellent for scraping and cleaning pipelines.
• Características: Lower friction than cup pigs, suitable for long-distance runs and high-velocity flows.

5. Foam Pigs

• Description: Made entirely of open-cell or closed-cell foam, sometimes coated with polyurethane.
• Use: Used for drying, cleaning, and dewatering pipelines.
• Características: Lightweight, flexible, can easily navigate bends and diameter changes.

6. Ball Pigs

• Description: Spherical pigs made of solid or inflatable materials like rubber or foam.
• Use: Typically used for liquid removal or product separation.
• Características: Simple design, can flow with the product, often used in gas pipelines.
