The branch connection could be required to bypass a gas pipeline section due for repair, outlet pipe replacement, Water pipe alteration or a gas pipe relocation.

Under pressure drilling or hot tapping enables the installation of a connection without any disruption to the live pipeline. This method live welds or mechanically fits an isolating valve to a short section of the pipe. Once the isolation valve is fitted it is opened to allow the drilling tool to be screwed or flanged into place. When the pipe has been drilled to the maximum hole the isolation valve is turned off and all drilling equipment is removed.
