Device UDP-F1

The UDP-F1 device is used for the temporary closing of pipelines with interior gas media positive pressure using closing balloons. The balloon is made of special antistatic rubber fixed to a plastic hose with pressed in safety quick acting coupling system installed in the loading chamber with a de-aeration valve. It is introduced to the pipeline through a loading fitting. The pipeline is closed upstream a closing element by filling the balloon with air or an inert gas. The devices UDP-F1 are designed and manufactured as kit systems allowing for a high level of variability. Normally they are supplied as the below described sets or sets individual configured based on customer´s requirements. The application range of individual sets may be extended using optional accessories (following the sheet 2.3-2). The devices comply with requirements of CSN EN 1775:2008, art. 8.2.3. as they are designed in a way excluding any leak of media during any operation.
