Zusammenfassung:The present invention relates to a non-welded joint pipe manufacturing apparatus that can easily connect pipes without welding and manufacture a non-welded joint pipe with improved durability and safety. The non-welded joint pipe manufacturing apparatus according to the present invention is an apparatus for manufacturing a pipe, comprising: a hollow body part having a first diameter; an expanded pipe part formed at an incline with a diameter gradually increasing from both ends of the body part; and a straight pipe part extending from the end of the expanded pipe part and having a second diameter greater than the first diameter. The apparatus comprises: a bod; a raised part raised from the upper surface of the body to insert and expand the pipe; and an insertion groove part recessed on the upper surface of the body along the outer circumferential surface of the raised part to form the straight pipe part. The raised part includes an expanded pipe forming part disposed at an incline with a diameter increasing from the first diameter to the second diameter to form the expanded pipe part of the pipe. 본 발명은 무용접 이음 배관 제조장치에 관한 것이다. 본 발명에 따른 무용접 이음 배관 제조장치는, 중공형이며 제1직경을 가지는 본체부와, 상기 본체부의 양측 단부로부터 직경이 점차 확장되어 경사지게 형성되는 확관부와, 상기 확관부의 단부로부터 다시 연장되되 상기 제1직경보다 큰 제2직경을 가지는 직관부를 구비하는 배관을 제조하기 위한 장치로서, 바디부; 바디부의 상면으로부터 돌출되어 배관이 삽입되어 확관되는 돌출부; 돌출부의 외주면을 따라 바디부의 상면에 오목하게 형성되어 직관부를 성형하기 위한 삽입홈부;를 구비하며, 돌출부는 직경이 제1직경으로부터 제2직경까지 커지게 경사지게 배치되어 배관의 확관부를 형성하기 위한 확관성형부를 구비하는 것에 특징이 있다.
