Claims (5)

  1. 내부 케이싱벽과 오부 케이싱벽 및 기부를 구성하는 얇은 벽으로된 케이싱내에 금속분말이나 금속합금분말을 주입하고,기부로부터 떨어진 면위를 원형 뚜껑으로 케이싱을 밀폐한 다음 냉간등압으로 단단하고 치수적으로 안정한 파이프브랭크 또는 콤펙트를 제조한 후 열간가공함에 있어서, 내부파이프에 적어도 하나의 벌지를 적어도 하나의 끝단에 형성시켜 열간가공함을 특징으로 하는 분말야금에 의한 파이프의 제조방법.
  2. 제1항에 있어서, 벌지는 각각 내부파이프 또는 내부파이프벽의 끝단에 로울러, 로울 또는 이와 유사한 방법에 의해 점차적으로 외부로 확대되게 한다는 것.
  3. 제1항 또는 제2항에 있어서, 내부파이프 또는 내부파이프 양단의 일단은 각각 원주를 따라 형성시킨 벌지를 적어도 하나 구성한다는 것.
  4. 제1항 내지 제3항중 어느항에 있어서, 파이프브랭크 또 콤펙트에 벌지를 형성시킬 부분만이라도 아닐링하고 이로인해 형성된 산화층을 제거한 다음 벌지를 형성시킨다는 것.
  5. 제1항 내지 제4항중 어느항에 있어서,변이부 특히 벌지와 내부파이프 또는 내부파이프벽 사이의 변이부 반경(r1,r2,r3)은 비교적 큰 반경을 가지기 때문에 벌지의 반경은 비교적 얕은 단면을 가진다는 것.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
