The UNISPHERE™ pig, a seamless, liquid-cast polyurethane ball, is designed for easy loading in an automated pig launcher for batching and displacement jobs. Gravity makes the automated launching and receiving of these spheres an easy process.

The UNISPHERE pig also is ideally suited to help pipeline owners and operators remove liquids from natural gas lines. It can be used with liquid or dry natural gas, sweet or sour crude oil, and refined hydrocarbon products.

Available in sizes 4 inches through 56 inches, the UNISPHERE pig can be inflated or deflated to fit most pipeline interiors, from standard wall to ultra-thin wall pipes. The sphere’s polyurethane composition provides strong resistance to abrasion, low temperature, and hydrocarbons, along with maximum flexibility and tear strength. The spheres also can be further inflated to compensate for wear.
