Abstract
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.
Claims8
A pipe connection device comprising:
- a pipe including a first region and a second region extended perpendicularly to the first region;
- and
- a flange including a coupling hole into which at least a portion of the second region of the pipe is joined,
- wherein the coupling hole includes:
- a first part including a serration and extended in parallel with a thickness direction of the flange;
- a second part including an inclined surface extending from the first part to one side surface of the flange while being inclined based on the thickness direction of the flange;
- and
- a third part extending from the first part to the other side surface, which is opposite to the one side surface of the flange, in parallel with the thickness direction of the flange,
- wherein the serration includes:
- a first surface formed in parallel with a peripheral surface of the first part;
- second surfaces formed to be inclined with respect to the first surface;
- and
- a protrusion formed by two of the second surfaces, and
- wherein an angle between the two second surfaces forming the protrusion is formed to be 100 degrees to 120 degrees.
A flange for pipe joint comprising:
- a coupling hole into which at least a portion of an external pipe is joined,
- wherein the coupling hole includes:
- a first part including a serration and extended in parallel with a thickness direction of the flange;
- a second part including an inclined surface extending from the first part to one side surface of flange while being inclined based on the thickness direction of the flange;
- and
- a third part extending from the first part to the other side surface, which is opposite to the one side surface of the flange, in parallel with the thickness direction of the flange,
- wherein the serration includes:
- a first surface formed in parallel with a peripheral surface of the first part;
- second surfaces formed to be inclined with respect to the first surface;
- and
- a protrusion formed by two of the second surfaces, and wherein an angle between the two second surfaces forming the protrusion is formed to be 100 degrees to 120 degrees.
