It is applied for sealing of welded side pipe nipples of DN= 150 mm for the use of ensuring disassembly of a gate valve.
The device is fastened with the flange on the gate valve of the disassembled side pipe nipple. The removable sealing cap is entered through the gate valve into a side pipe nipple and fixed sealably in it. Further the gate valve together with the device is dismantled, and on the flange of the side pipe nipple a metal cap is established.
|Nominal inside diameter of the dismantled gate valve||150 mm|
|Pressure in the pipeline during dismantling||1 MPa|
|Pressure in the pipeline after dismantling||6,3 MPa|
|Overall dimensions, mm||1670х340х340|
