Process pigs are designed for use in multi-product piping applications for industries including chemical & petrochemical, ink & paint, food & beverage, cosmetic & pharmaceutical for process, packing, storage, and loading/ unloading lines. The unique designs of the process pigs minimize bypass, thereby minimizing cross-contamination and normally wasted product. For more information regarding this type of pig and its unique closed-loop pigging method, view the Flash animation and PowerPoint presentation found in " The Process Pigging System" link on the green navigation at the left side of this screen.
