파이프 규격과 스케쥴

 

파이프 규격현황

 

 

 

파이프는 인치 단위로 생산하고, 파이프의 호칭은 몇A로 부르며,  몇A 마다 몇 인치로 구분된다.

 예를 들면, 10A- 3/8인치,  15A- 1/2인치,  20A- 3/4인치,  25A-  1  인치 ...등등

 

파이프는 같은 외경을 가졌다고 해도 용도에 따라 두께가 다른데, 이것을 스케쥴(SCHEDULE)로 구분하며 스케쥴은 #로 표시한다.

 예를들면,  탄소강 파이프 규격을 20A #80로 표기했을때               

                 이것을 Ø(파이)로 바꿔 표시한다면(JIS규격일때)  Ø27.2 - 3.9 t 가 된다.

                 다시 말해, 이 파이프는20A 파이프이며, 외경이 27.2mm이고  스케쥴(#)80짜리로 3.9mm 두께의 파이프이다.

                                 따라서 내경은 외경27.2 에서 두께3.9를 빼면 된다.
