Line Stop Devices and Pipe Closing Plugs

The device RVB-F1 is used for temporary pipeline closing. The closing body (balloon) is made of special rubber and it is fixed to the loading rod. Using a loading chamber, it is loaded in a way that prevents any media leaks to the pipeline. The pipeline is closed by filing the closing body with liquid using a pressure and suction pump. In order to improve safety, the closing body is supported by a supporting arm or a cylinder that prevents the body from moving in the gas flow direction. The loading chamber is attached to the pipeline by a balloon adapting piece upright to the axis of the closed pipeline (for ballooning adapters – following the sheet the part 4 of the catalogue). The design of the loading chambers and rods makes it possible to monitor the closed up section during the closing period or, as the case may be, to de-aerate the section, de-gas it or flush it with inert gas. The device is conceived in a way to allow for the execution of all works including the closing of the balloon adapting piece without any media leaks. The devices RVB 2010-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 individually configured based on customer´s request.
