  • Patent number: 10302234
    Abstract: The present flow-undisrupted process includes: enclosing a portion of an existing pipe with a sealing case; connecting a boring machine to the sealing case in a non-valve state in which no operation valve is interposed between a projecting pipe portion of the sealing case and the boring machine; forming a circular opening in an area of the existing pipe corresponding to the projecting pipe portion by means of a hole saw of the boring machine; rotating a tee and the boring machine in a circumferential direction of the existing pipe to a position at which the projecting pipe portion is completely past the opening; after the rotation, maintaining a sealed state in which the seal packing prevents a pressure of a fluid inside the existing pipe from being applied to the projecting pipe portion; and removing the boring machine from the projecting pipe portion in the sealed state.
