Description

고압유체 공급관의 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 횡축을 내부표면으로부터의 거리(mm)로 하고 종축을 잔류응력(kgf/㎟)로한 본 발명에 따른 제품의 잔류응력 분포도,
제2도는 (100kgf/㎠)의 내부 압력을 가한 경우의 제1도와 유사한 이론적 응력 분포도.

Claims (7)

  1. 외부공급관을 내부공급관의 외부원주에 견고하에 결합시킨 이중 공급액구조의 고압유체공급관의 제조방법에 있어서, 내부공급관보다 더큰 열팽창계수를 가지는 외부공급관과 그 내부공급관을 그 사이에 브레이징재료를 넣고 억지 끼워맞춤하여 이중공급관을 형성하는 단계와, 적어도 내부공급관의 내부표면에 잔류 압출응력을 부여하기 위하여 그 이중공급관을 열처리하고 서냉하여 내부공급관과 외부공급관을 서로 일체로 완전히 접합하고 견고하게 결합하는 단계를 포함하는 것을 특징으로하는 고압 유체공급관의 제조방법.
  2. 제1항에 있어서, 내부공급관과 외부공급관의 벽두께비율이 1:4 내지 1:2범위내인 것을 특징으로하는 고압 유체공급관의 제조방법.
  3. 제1항에 있어서, 브레이징재료의 융점이 내부와 외부공급관보다 낮은 것을 특징으로하는 고압 유체공급관의 제조방법.
  4. 제1항에 있어서, 브레이징 재료가 극히 얇은 박판재의 형태나 도금형태로 배치되는 것을 특징으로하는 고압 유체공급관의 제조방법.
  5. 제1항에 있어서, 다이스와 플러그를 이용한 인발가공에 의해서 내부공급관과 외부공급관의 견고한 결합이 이루어지는 것을 특징으로하는 고압 유체공급관의 제조방법.
  6. 제5항에 있어서, 인발가공이 가열 또는 고온상태에서 행하여지는 것을 특징으로하는 고압 유체공급관의 제조방법.
  7. 제1항에 있어서, 서냉처리가 20℃/min 이하의 냉각속도로 행하여지는 것을 특징으로하는 고압 유체공급관의 제조방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
