PE 파이프를 PPR 파이프에 직접 연결할 수 있는지 여부, 주의해야 할 사항은 무엇입니까?

2025-08-18

플라스틱 파이프의 설치 및 사용에서 서로 다른 재료의 파이프 연결에 문제가 있는 경우가 많은데, 그 중 PE 파이프와 PPR 파이프 사이의 연결이 더 일반적인 상황입니다. 많은 사람들이 PE 파이프가 PPR 파이프에 직접 연결될 수 있는지 물을 것입니다. 대답은 아니오입니다. PE 파이프와 PPR 파이프는 뜨거운 용융으로 직접 연결될 수 없습니다. 이것은 주로 두 파이프의 재료 특성에 의해 결정됩니다. PE 파이프의 주요 구성 요소는 폴리에틸렌이고 PPR 파이프는 무작위 중합체 폴리프로필렌이며 분자 구조, 고온 용융 온도 및 물리적 특성이 크게 다릅니다. 고온 용융으로 직접

따라서 PE 파이프와 PPR 파이프를 연결해야 할 때 어떤 방법을 사용해야 합니까? 가장 일반적이고 신뢰할 수 있는 방법은 감압기 직접 또는 플랜지 조인트라고도 하는 어댑터 조인트를 사용하는 것입니다. 어댑터 조인트는 일반적으로 한쪽 끝은 PE, 다른 쪽 끝은 PPR로 제작되거나 금속 소재(황동 등)가 전환으로 사용되며, 두 끝은 PE 파이프 및 PPR 파이프와 뜨거운 용융 또는 와이어 버클에 의해 연결됩니다. 어댑터 조인트를 선택할 때는 사양이 PE 파이프와 연결된 PPR 파이프의 직경과 일치하고 제품 품질이 연결의 안정성과 내구성을 보장하기 위해 관련 표준을 충족하는지 확인해야 합니다. 117277798 우선 파이프라인 연결부의 끝면이 깨끗하고 오일, 불순물, 습기가 없는지 확인하여 뜨거운 용융이나 연결 효과에 영향을 미치지 않도록 해야 합니다. 둘째, 파이프라인을 절단할 때는 절개가 평평하고 수직인지 확인하고 어댑터와 밀착되도록 탄이나 비뚤어지지 않도록 특수 파이프 절삭 공구를 사용해야 합니다. 고온 용융으로 연결된 부분(예: 어댑터의 PE 끝과 PE 끝, 어댑터의 PPR 끝과 PPR 끝)의 경우 파이프 및 고온 용융 기계의 지침에 따라 고온 용융 온도와 시간을 엄격하게 제어할 필요가 있습니다. 온도가 너무 높거나 가열 시간이 너무 길면 파이프가 과도하게 녹거나 파이프가 막히거나 연결 강도가 저하될 수 있습니다. 온도가 너무 낮거나 가열 시간이 충분하지 않으면 연결이 단단하지 않아 누출의 숨겨진 위험이 남습니다.

연결이 완료된 후에는 인터페이스가 자연적으로 냉각되고 굳어질 때까지 기다려야 합니다. 강제로 움직이거나 외부 힘을 가하지 마십시오. 또한 전체 설치 과정에서 선택된 파이프 재료와 어댑터 조인트의 압력 수준이 실제 요구 사항을 충족할 수 있도록 파이프라인 시스템의 작동 압력 및 사용 환경도 고려해야 합니다. 설치가 완료된 후에는 시스템 압력 테스트를 수행하여 연결부의 밀봉 및 신뢰성을

요컨대, PE 파이프와 PPR 파이프는 직접 고온 용융 버트가 될 수 없으며 적절한 어댑터 조인트를 통해 연결되어야 합니다. 연결 작업에서는 표준 시공 프로세스를 엄격히 준수하고 재료 선택, 청소, 절단, 고온 용융 파라미터 제어 및 사후 검사 및 기타 링크에 주의를 기울여 파이프라인 연결의 품질을 효과적으로 보장하고 전체 파이프라인 시스템의 안전하고 안정적인 작동을 보장합니다
