Foam Pigs
Foam pigs are employed in many different processes, including cleaning, gauging, batching, dewatering, drying, and flooding. The suitability of pipelines for pigging less flexible pig types, like metal-bodied pigs, can also be demonstrated using foam pigs. Propipe Foam pigs’ flexibility makes it safe to run in lines with wax or scale buildup, particularly when deposit volumes are unknown. From basic swabbing or scout pigs (for line proving) to heavy density wire brush or studded pigs, foam pigs can be supplied with a range of aggression.

Pipeline Foam Pigs are a type of pipeline cleaning and maintenance tool used to clean, inspect, and maintain pipelines in various industries, including oil and gas, petrochemical, and water treatment.
What are Foam Pigs?
Foam Pigs are cylindrical or spherical devices made of a flexible, foam-like material, typically polyurethane or polyethylene. They are designed to be inserted into a pipeline and pushed through by fluid pressure, allowing them to clean and inspect the pipeline as they move through.
Types of Foam Pigs
1. Cleaning Pigs: Used to remove debris, sediment, and contaminants from pipelines.
2. Inspection Pigs: Used to inspect pipelines for damage, corrosion, or other defects.
3. Gauge Pigs: Used to measure pipeline diameter and detect any restrictions or blockages.
4. Sealing Pigs: Used to seal pipelines and prevent leakage.
Benefits of Foam Pigs
1. Effective Cleaning: Foam Pigs can remove a wide range of contaminants and debris from pipelines.
2. Reduced Maintenance: Regular use of Foam Pigs can help reduce the need for more invasive and expensive maintenance procedures.
3. Improved Safety: Foam Pigs can help identify potential safety hazards, such as pipeline damage or corrosion.
4. Increased Efficiency: Foam Pigs can help optimize pipeline flow rates and reduce energy consumption.
Industries that Use Foam Pigs
1. Oil and Gas: Foam Pigs are widely used in the oil and gas industry to clean and maintain pipelines.
2. Petrochemical: Foam Pigs are used in petrochemical plants to clean and inspect pipelines.
3. Water Treatment: Foam Pigs are used in water treatment plants to clean and maintain pipelines.
4. Other Industries: Foam Pigs are also used in other industries, such as power generation, chemical processing, and food processing.
Foam pigs are incredibly useful pigs made for cleaning, scraping, or drying pipelines. A short pipeline can be dewatered using a foam pig coated with polyurethane. A flexible, bullet-shaped polyurethane foam cylinder makes up the design, and the back is concave to increase pressure. This eliminates product contamination by strengthening the seal against the pipe wall and preventing propelling agent by-pass. There are three different density specifications for foam pigs: high, medium, and low. The type of application will dictate which density is best. For instance, a high-density pig would be ideal for longer runs with several turns and vigorous cleaning action, while a low-density pig might be used for drying and light cleaning tasks.
