Description:
UNISPHERE™ Pigs are seamless, liquid-cast, polyurethane balls used for heavy-duty service in the removal of liquid hydrocarbons and water from pipelines and piping systems.
"Spheres" are filled with liquid, usually a water/glycol mixture, then inflated under pressure to match pipe ID. An inflating valve is constructed into the pig.
UNISPHERE Pigs are available in 4" through 56" (100-1400 mm). |
