Process pigs are designed for use in multi-product piping applications. The industries utilizing these pigs include chemical and petrochemical, ink and paint, food and beverage, cosmetic, and pharmaceutical industries. The process pigs are intended for use in packing, storage, and loading/unloading lines. The unique designs of the process pigs minimize bypass, thereby minimizing cross-contamination and normally wasted product.
