Mecalsys produces low density foam pigs used for light pipeline cleaning, drying, and product displacement operations. These pigs are made from lightweight polyurethane foam that provides excellent flexibility and compressibility.

Low density foam pigs are particularly suitable for pipelines with multiple bends, diameter changes, or delicate internal coatings. Their soft structure allows them to move smoothly through pipelines without damaging internal surfaces.

They are commonly used in pipeline operations that require gentle cleaning or fluid displacement.
