Pigging system

Flexmatic manufactuers and installs pigging systems for the food industry.  A pigging system is best suited where there is a need for total phase separation, for example, when the product is highly viscous and the product cost is high.  Large savings can be realised here by preventing product wastage.

A pigging system is used for mechanical cleaning of pipe installations or for securing separation of product/product, product/rinse water or to push out product after the end of production.

The pigging system consists of a pigging unit (often called the pig) that is pushed through the pipe grid by the means of a pressurized liquid or gas. The slats of the pig scrapes the pipes internally so that the cleaning process can be greatly reduced as sediments are removed.

The second frequent usage of a pigging system is for the separation of product from either product or rinse water. Again it is the slats that secure that there is no exchange of product between the ends of the pig. For the most secure separation of product/product it is possible to install a dual pig system with the possibility of product/rinse water/product.

The pig alone is not sufficient and accessories for handling the pig have to be installed on the piping grid. Valves on the grid must be compliant for the passage of a pig. Flexmatic can assist on the design and selection of valves and pipe layout, as well as other necessary accessories for sending, receiving and cleaning of the pig.
