Description

The Dewatering Pig is a tool used for the cleaning and maintenance of oil and gas pipelines, primarily for removing water and other liquids from the pipelines. It plays a crucial role in pipeline maintenance, especially in the drying and cleaning processes.

Main Functions of Dewatering Pig

• Moisture Removal: Used to discharge water from the pipeline, ensuring it is dry to prevent corrosion and bacterial growth.
• Impurity Cleaning: Capable of removing mud, debris, and other solid impurities within the pipeline to maintain unobstructed flow.
• Corrosion Reduction: By removing moisture, it lowers the risk of pipeline corrosion, extending its lifespan.

Features

• Material: Typically made from polyurethane foam, which provides good water absorption and elasticity.
• Design: Features spiral patterns or grooves on the surface to enhance cleaning effectiveness and ensure close contact with the pipe walls.
• Variety in Size: Available in various sizes to match the inner diameter of the pipeline, ensuring a tight fit.
• Ease of Operation: Moves through the pipeline driven by pressure, requiring no additional power.

Application Scenarios

• New Pipelines: Used for drying newly laid pipelines to ensure they are free of moisture.
• Maintenance: Regularly cleans pipelines to prevent the accumulation of impurities and moisture.
• Post-Repair Treatment: Used for cleaning and drying pipelines after repairs.

Advantages of Dewatering Pig

• Efficient Cleaning: Effectively removes moisture and impurities, enhancing pipeline operational efficiency.
• Economical and Practical: Low cost, reusable, and low maintenance expenses.
• Safe and Environmentally Friendly: Does not require chemical agents, reducing environmental pollution.
