‘Pigs’ are projectiles used to recover residual liquid from process pipelines. Pigging systems significantly increase yields, save product, reduce water and chemical usage, speed up changeovers and CIP, as well as a range of other benefits. That’s why companies throughout the world use pigging – it’s used in everything from chocolate and confectionery production, to wine, paint, cosmetics, toothpaste, shaving foam, soaps, soft drinks, ready meals, and many other processes. In fact, just about anything that can be pumped can be pigged. This video shows two methods of propelling pigs through pipelines – by air and by product.
