Closing balloons

Closing balloons are devices used for the temporary closing of the medium flow in the pipeline. Working part of the closing balloon is made of flexible hollow body that is filled with gas or liquid after being loaded to the pipeline. It will cause closing of the line and stop the media flow. The flexible body may be provided with a protective jacket. It is fixed to the loading part of the closing balloon that consists of various components based on specific requirements to the balloon application (loading the balloon to the pipeline, check and control of its filling etc.) The loading to closed pipelines is recommended for the sake of safety and extension of the balloon technical life to be done just using drilled openings with properly deburred edges. Fore safety reasons, the service life of some types of balloons may be limited. For detailed description, application specification, properties and technical data of individual series of closing balloons following the sheet descriptions below in following catalogue sheets.
