Hot Tapping is defined as using an under pressure drilling machine to cut a hole in an operating pipeline which allows for a new branch connection from the original pipe. This process is done without any product leakage or interruption of flow. The method employs a tapping machine, a full-ported valve, and a pressure containing fitting attached to the existing pressurized system. During tapping, a pilot drill penetrates the line and its contents enter the head and will remain there throughout the tap. When the hot tap is completed the “coupon” or cut portion of the pipe, which is normally retained by the pilot drill wires, is lifted out and the valve is closed.
