The fitting has a tapping unit (40) attached with a borer (42) on a tapping nozzle for tapping a pipe (100), where the tapping fitting is connected with the pipe. A valve i.e. spherical valve (20), is integrated in the tapping nozzle. The valve is opened, when the tapping unit is blocked. A ball tap (30) is fetched in a closed condition, so that the tapping nozzle and the pipe are fluidly separated from each other. The ball tap is removed, and the tapping unit is released for unlock. The ball tap is positioned on an outlet, and tapping nozzle is closed opposite to the pipe. |
