Pipeline Pigs

1. Product Overview

Pipeline cleaning devices (PIGs) are special spheres or cylindrical tools inserted into pipelines and propelled by fluid pressure (oil, fuel, gas). This process, known as pigging, is used to remove deposits, displace residual liquids, or inspect internal defects without shutting down the system.

2. Standard Technical Specifications

3. Why Regular Pigging is Necessary

• Maintain flow capacity: Removes deposits on pipe walls, reducing friction and keeping pressure stable.
• Prevent corrosion: Eliminates stagnant water and chemical residues at low points, extending pipeline life by decades.
• Ensure product quality: Prevents contamination or cross-mixing of fuels transported in the same pipeline.
• Safety inspection: Smart PIGs can detect dents, leaks, or micro-corrosion inside pipelines.

4. Key Features

• Flexibility: Designed to pass through elbows with small bending radii without getting stuck.
• Superior wear resistance: Polyurethane material withstands friction over long distances (tens of kilometers).
• Effective cleaning: Discs and cups fit tightly against pipe walls, ensuring complete removal of residual liquids.
• Integrated tracking: Can be equipped with transmitters for technicians to monitor PIG location above ground.

5. Practical Applications

• Fuel depots: Cleaning pipelines from ships to storage tanks at terminals.
• Gas pipelines: Removing condensate and impurities in natural gas transmission lines.
• Food industry: Pushing out remaining product (milk, juice) before CIP cleaning to avoid waste.
• Routine maintenance: Using steel-brush PIGs to remove rust inside old pipelines.
