Plugging systems Block Device (TABU) are designed to shut off the pipeline during repair work and tie-in work without disconnecting consumers. The equipment is mounted on valves and is designed to be used in conjunction with straight fittings and tee fittings.
Plugging system Block-Device (TABU) are equipped with flange adapters for mounting on valves and equipped with outlets for organizing bypass lines.
The working element designed to seal the pipe cavity is a cuff of trapezoidal section, which is deformed by two plates having inner tapered surfaces.
Depending on the size and operating pressure of the pipeline, the equipment can be equipped with a manual or hydromechanical drive of plates and various mechanisms for input / output of blocking heads into the cavity of the pipeline (manual or hydraulic).
Block-Device (TABU) can be equipped with video surveillance points connected to the video diagnostic system and allowing to visually control the equipment operation process in real time.
Power to the hydraulic drives of the Block-Device (TABU) is carried out from a hydraulic oil station with a working pressure of 14.0 MPa and a flow rate of 30 l / min.
