PE 파이프 sdr은 무엇을 의미합니까?

2025-08-19

PE 파이프의 선택과 적용에서 우리는 종종 "SDR"이라는 용어를 접하게 됩니다. 비전문가의 경우 SDR이 약간 낯설어 보일 수 있습니다. 그렇다면, PE 파이프의 SDR은 정확히 무엇을 의미할까요? 그 의미는 무엇입니까? 이 기사에서는 자세히 설명하고 AD 파이프의 PE 파이프 제품과 함께 설명합니다.

SDR, 전체 이름은 표준 치수 비율로 중국어로 "표준 크기 비율"로 번역됩니다. PE 파이프의 중요한 기술적 매개 변수입니다. 이것은 특히 파이프의 공칭 벽 두께(en)에 대한 공칭 외경(den)의 비율을 나타냅니다. 공식으로 표현됩니다: SDR = den/en

이 정의에서 SDR은 실제로 PE 파이프의 외경 두께와 PE 그렇다면, 이 비율의 실제적인 의미는 무엇일까요? 일반적으로 SDR 값이 클수록 동일한 공칭 외경 아래에서 파이프라인의 공칭 벽 두께가 얇아집니다. 벽 두께의 얇아짐은 파이프라인의 압력 지지 용량에 직접적인 영향을 미칩니다. 따라서 PE 파이프의 SDR 값이 클수록 견딜 수 있는 내부 압력이 낮아집니다. 반대로 SDR 값이 작을수록 파이프라인의 벽 두께가 두꺼울수록 압력 지지 용량이 강해집니다.

실제 적용에서 AD 파이프와 같은 전문 제조업체는 공통 SDR11, SDR17.6, SDR21, SDR26 등과 같은 다양한 SDR 사양을 포함하는 일련의 PE 파이프 제품을 생산합니다. 이러한 엔지니어링 설계자는 특정 전달 매체, 작업 압력, 배치 환경 및 프로젝트 비용 등 다양한 요소에 따라 적절한 SDR 사양의 PE 파이프를 선택합니다.

예를 들어, 고압의 수돗물을 전달하는 주 파이프인 경우 SDR 값이 더 작고 벽 두께가 두껍고 압력 베어링 용량이 더 강한 PE 파이프가 일반적으로 선택됩니다. 고압이 필요하지 않은 일부 배수, 하수 또는 농지 관개 시나리오의 경우 SDR 값이 더 크고 상대적으로 경제적인 PE 파이프를 선택할 수 있습니다. AD 파이프의 생산 과정에서 각 PE 파이프 제품의 SDR 값이 설계 요구 사항을 충족

PE 파이프의 SDR의 의미를 이해하면 엔지니어링 품질과 사용 효과를 보장하기 위해 PE 파이프를 보다 과학적이고 합리적으로 선택하고 사용하는 데 도움이 될 것입니다. PE 파이프를 선택할 때 SDR 선택에 의문이 있는 경우 전문 기술자나 AD 파이프와 같은 일반 생산 회사에 문의하여 프로젝트 요구에 가장 적합한 솔루션을 얻는 것이 좋습니다.
