  • Method and means for connecting a branch conduit to an existing conduit
    Patent number: 5065780
    Abstract: A method and apparatus for connecting a branch conduit to an existing conduit (9) through a valve (1, 2), the valve being connected to the conduit in such a way that its flow channel (8) is directed tangentially of the conduit (9). A tool (12, 16, 20) is fixed to the outlet of the valve to cut an opening in the conduit (9) through the open valve (1, 2). The tool is designed with a piston having a side recess (13) formed with a cutting edge (20) so that when the piston is retracted from the flow channel, a portion (14) of the conduit (9) is severed and the severed portion (14) will be caught by and retained within the recess. After closing the valve, the tool is dismounted, the portion (14) is removed together with the tool and the branch conduit is connected in replacement of the tool.
