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.
Diameter and material of the closed pipeline:
Steel pipeline DN65 up to DN 300
PE pipeline 75 up to 315 mm
The application of pipelines made of other materials is subject to consultation with the manufacturer.
Natural gas, water, other non-aggressive gases and liquids. *
The maximum pressure in the closed pipeline: **
Up to 3 bar
Working temperature: ***
-10 / +130 °C
* Other media possible only after consultation with the manufacturer.
** The maximum pressure in closed pipeline depends on the closed pipeline dimension – following the sheet 2.1.-1.1.
*** The boundaries of the temperature range are based on the type of used balloons.
