Line Stop Devices and Pipe Closing Plugs

The RUP-F2 device is used for temporary closing of pipelines with an interior medium positive pressure and for the follow up replacement of defective closing fittings (ball valve) or short-term pipeline shut-downs using rubber stopplers. A stoppler made of special antistatic rubber installed in the loading chamber with a de-aeration valve is introduced to the pipeline via a closing fitting by means of loading rod or a flexible cable hose. The pipeline is closed by the extension of the rubber element in the pipeline by turning the control nut provided in the control part of the loading rod or the flexible cable hose. The flexible cable hose is used primarily at places where there is lack of handling space where the loading rod cannot be used for instance because of distance or pipeline bends between the place of closure and loading. The RUP-F2 devices 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 devices comply with requirements of CSN EN 1775:2008 art. 8.2.3 as they are conceived so that all works could be done without any media leaks. The application range of individual sets may be extended using accessory equipment (following the sheet 2.3-2).
