With this station the loading and unloading of the pig from a pipe system is also easy, fast and safe. A part of the station can be swivelled out of the pipeline. Thus, a pressure free loading or unloading of the pig is secured. So the process of pig exchange is made easier and operational errors are avoided. The pipeline side can be equipped either with a flange or a female sliding coupling. Due to safety reasons I.S.T. recommends the use of this station.
