PIPE CONNECTION DEVICE
A pipe connection device may include a pipe and a flange. The pipe may include a first region and a second region extended perpendicularly to the first region. The flange may include a coupling hole into which at least a portion of the second region of the pipe is joined. The coupling hole may include a first part and a second part. The first part may include a serration and be extended in parallel with a thickness direction of the flange. The second part may include an inclined surface formed to be inclined based on the thickness direction of the flange, and be extended from the first part to one side surface of the flange.
