Criss Cross & Wire Brush Foam Pigs

Criss-cross foam pigs are constructed of light, medium, or heavy density foam and coated with polyurethane elastomer in a criss-cross pattern. Foam pigs with a crisscross pattern are a specialized type of pipeline pig designed to enhance the cleaning and scraping efficiency of the pig. The crisscross pattern typically involves grooves or channels cut into the surface of the pig. Here’s a detailed look at their features, uses, and advantages:

1. Foam Core: The pig is made from a flexible polyurethane foam, allowing it to adapt to various pipeline geometries.
2. Crisscross Pattern: The surface of the pig is designed with a series of intersecting grooves or channels, creating a crisscross pattern. This pattern increases the surface area for contact with the pipeline interior.
3. Durability: The foam can be coated or uncoated, depending on the specific application and requirements. Coated versions often use materials like polyurethane for enhanced durability.
4. Flexible Design: The crisscross grooves can vary in depth and width, tailored to the specific cleaning needs of the pipeline.
