The I.S.T. Duo-pig is used universally due to its form and the wide variety of elastomers it can be made from (AU, FKM, EPDM, NBR etc.). It is robust and simple to handle. Without having to take it out of th epipeline it can be rinsed in the pigging stations. The pig can be detected in the stations or in the pipeline due to its integrated magnet. For manual systems the Duo-pig can also be supplied without magnet. In this case it would be detected with manual pig locators.
Only available in conjunction with I.S.T. pigging valves or systems
