What is Pipeline Pig?

Pipeline pig is a specialized tool used for cleaning, inspecting, and maintaining pipelines. These devices, also known as pipeline scrapers or pipeline cleaners, are inserted into the pipeline and propelled through it by the flow of the product or by mechanical means. Pipeline pigs are typically cylindrical in shape and are designed to fit snugly within the pipeline diameter.

The 2-Cup Pipeline Pig with Brushes: An Overview

The 2-cup pipeline pig with brushes combines the efficiency of a skeletal pig with the added benefit of brush attachments, making it an excellent choice for pipeline maintenance. This cleaning tool is designed to provide a high level of flexibility and adaptability for various pipeline conditions. The pig’s structure consists of two cups made of durable materials such as rubber, polyurethane, or fluorine rubber, along with brush attachments for enhanced cleaning performance.

Key Features of the 2-Cup Pig with Brushes

High Flexibility: The 2-cup pig with brushes is designed to navigate through bends, elbows, and other challenging sections of the pipeline, ensuring that all areas are thoroughly cleaned.

Enhanced Cleaning Performance: The brush attachments on this pig help remove stubborn debris, deposits, and other contaminants from the pipeline’s inner walls. This additional cleaning capability ensures a more effective and comprehensive pipeline cleaning operation.

Suitable Sealing Property: The cups on the 2-cup pig with brushes provide a strong seal against the pipeline walls, ensuring that contaminants are pushed forward and removed from the pipeline during the cleaning process.

Long-Lasting and Durable: Made from high-quality materials, the 2-cup pig with brushes is designed to withstand the harsh conditions within oil and gas pipelines and provide extended service life.

Applications of the 2-Cup Pig with Brushes

The 2-cup pig with brushes is suitable for various pipeline maintenance tasks, including:

Pipeline Cleaning: The primary function of the 2-cup pig with brushes is to clean the inside of oil and gas pipelines. The brush attachments help remove accumulated debris and contaminants, ensuring a smooth and efficient flow of resources.

De-Watering: This pig can be used to remove water from pipelines, ensuring that the transported materials remain uncontaminated.

Isolation of Pipeline Sections: During maintenance or inspection tasks, the 2-cup pig with brushes can be used to isolate specific sections of the pipeline, preventing the unintentional mixing of different products.

Skeleton Materials:

Stainless Steel:

There are three types of skeleton materials available for pipeline cleaning pigs. The first type is stainless steel, which includes variants such as 316ss, 316lss, and 304ss. Stainless steel is a highly durable and robust metal, primarily due to its chromium and nickel content. Chromium forms an oxide layer on the metal’s surface, protecting it from corrosion and wear, while nickel enhances the metal’s strength and ductility. In addition, stainless steel offers excellent acid resistance. Pigs with stainless steel skeletons can accommodate transmitters, making them a suitable choice if you require this feature.

Carbon Steel:

Carbon steel is a more cost-effective option compared to stainless steel, but it cannot accommodate transmitters due to magnetic field interference. However, if the pipeline diameter (DN) is greater than or equal to 300, a transmitter can be added since the distance allows for separate operation without interference.

ABS:

For pipeline cleaning pigs with a diameter (DN) of 200 or smaller, ABS can be chosen as the skeleton material. Although it is more expensive than the other two materials, ABS effectively prevents explosions caused by sparks from impact, ensuring safety during operation. Additionally, ABS is lighter and offers strong acid resistance.

Selecting the Right 2-Cup Pig with Brushes

When choosing a 2-cup pig with brushes for your pipeline maintenance needs, consider the following factors:

Pipeline Diameter: Ensure that the pig you select is compatible with the diameter of the pipeline you need to clean.

Material Compatibility: Choose a pig with cups and brushes made from materials that are resistant to the chemicals and substances found in your pipeline.

Additional Accessories: Depending on your specific requirements, you may need to consider additional accessories, such as gauging discs, wire brushes, spring steel brushes, magnetic steel, or transmitters.

Skeleton Material: The skeleton material should be chosen based on factors such as durability, cost, and the potential need for a transmitter. Options include stainless steel, carbon steel, and ABS.

Accessories of Pipeline Pig

Pipeline cleaning pigs come with various accessories that enhance their functionality and effectiveness in maintaining the purity and efficiency of oil and gas pipelines. These accessories can be customized based on specific requirements and pipeline conditions. Here are some of the main accessories of pipeline cleaning pigs:

Cups: Cups are a key accessory of pipeline cleaning pigs, providing an effective seal against the pipeline walls while pushing debris and contaminants forward. Cups can be made from materials such as rubber, polyurethane, and fluorine rubber, depending on the specific application and pipeline conditions.

Discs: Discs are another primary component of pipeline cleaning pigs, offering guidance and support during the cleaning process. Discs can help cleaning pigs enter pipes more easily and enhance their overall performance. Typically, discs are made from polyurethane.

Gaskets: Gaskets are used to isolate the distance between cups or discs, ensuring proper spacing and support during the cleaning process. Gaskets between discs are typically polyurethane, while those used between cups can be made of nylon or steel, depending on the pig’s diameter.

Gauging Discs: Gauging discs are used to measure the internal diameter of pipelines and detect any anomalies or deformations. They are generally made to be 80%-95% of the pipeline’s inner diameter, with 85% being the most common size.

Wire Brushes: Wire brushes serve as an accessory to enhance cleaning performance by effectively removing stubborn debris, deposits, and other contaminants from the pipeline’s inner walls. Wire brushes can be made from materials such as carbon steel, stainless steel, or nylon, depending on the requirements and pipeline conditions.

Conclusion

The 2-cup pig with brushes is an essential tool for maintaining the cleanliness and efficiency of oil and gas pipelines. Its unique design, combining the benefits of a skeletal pig with brush attachments, ensures thorough and effective pipeline cleaning. When selecting a 2-cup pig with brushes for your pipeline maintenance needs, consider factors such as pipeline diameter, material compatibility, and additional accessories to ensure the best possible results.
