Now on the market for use in a variety of diameters are a new line of pipeline pigs like this.
Of durable construction, they achieve product recovery rates of 99+% and are flexible to negotiate 90°, 1.5-diameter elbows. Models can be supplied separately or as part of a pigging system. This allows injection of the pig into an encapsulated system to recover product or remove cleaning fluids between batches.
The pigs are propelled through a line via compressed air, nitrogen, carbon dioxide, water, or the next material to be used in production. This pigging procedure is said to allow faster product changeovers, reduce water consumption by up to 50%, and allow you to reduce your CIP chemical consumption by up to 30%. Full pigs data are free.
