Patent attributes
A device for hot tapping is disclosed. The device includes a tube having a bore with an opening in the tube in fluid communication with the bore. The tube is connected to a valve which is connected to a saddle connection mounted on a pipe element in a piping network. A boring tool is inserted through the tube and the valve and bores a hole in the pipe element. Fluid under pressure flows from the pipe element through the tube and out through the opening. Swarf generated by the boring is entrained in the fluid and is flushed out through the opening. The device also includes a saddle connection having projections which bite into the pipe element and prevent motion. A hot tapping kit including tubes of different diameters is also encompassed by the invention.
