Pigging technology has become an integral part in many different application fields. Here, in most industrial applications liquid media are pumped and the pipelines are used as a means of transport. Using pigging technology in the next process step the product is transferred out of the pipeline quickly, almost completely and cost effectively. Here the demands of each industry are different, but the pigging solutions are similar. In the following you will find more information about the different industries and the specific pigging systems as a completion of the industrial process.

Chemical Industry

Product handling in the chemical industry requires a superior technology. Cross-contamination as well as product hardening have to be avoided. With pigging technology these high quality standards can be implemented. Pigs with good chemical resistance and optimised scraping performance are as necessary as stations with almost no pockets as pig receiving and launching stations. I.S.T. has developed pigging systems for many different demands of the chemical industry. These systems guarantee process reliability in many industrial plants.

Lubricants and Additives

Industrial pigging technology has its seeds in the lubricant industry. Here the advantages of pigging were discovered early and therefore it has still been implemented in many industrial plants. The conditions of this lubricating product are ideal for the pigging process. In this industry the possibilities vary from simple manual systems up to complex constructions which interconnect many plant areas like a network with help of piggable pipelines. We have been successful in this field for more than 40 years.

Foodstuffs, drinks and tobacco

Products which can age or spoil require a production plant that can easily be cleaned. Components and equipment are designed considering hygienic requirements for a cleaning procedure without any residuals.

A pigging system especially designed for these requirements can drastically reduce the cleaning process periods. The pigging sequence is often done within a few minutes, so that complete product utilisation in the pipeline is facilitated. This leads to cost savings through product loss reduction and a quick re-availability of the equipment after short pigging / CIP sequences.
