뜨거운 PE 파이프를 회전시킬 수 있습니까?

2025-08-19

PE 파이프의 설치 및 시공에서 고온 용융 연결은 배관 시스템의 안전하고 안정적인 작동을 보장하는 핵심 프로세스입니다. 많은 건설 인력이 공통적인 문제에 직면하게 될 것입니다. 고온 용융 연결이 이루어질 때 PE 파이프를 회전시킬 수 있습니까? 플라스틱 파이프 분야에서 풍부한 경험을 가진 AD 파이프로서, 여기 이 작업의 주요 사항에 대한 자세한 분석이 있습니다.

우선, PE 파이프가 고온 용융 연결의 여러 단계에서 "회전"에 대한 요구 사항이 다르다는 것을 명확히 할 필요가 있습니다.

고온 용융 연결이 시작되기 전에, 즉 파이프와 피팅의 준비 단계에서 연결될 PE 이때 최상의 정렬 효과를 얻기 위해 필요한 경미한 각도 조정 또는 회전을 할 수 있습니다. 목적은 파이프 피팅의 파이프와 용접 표면을 완전히 맞추고 정렬 불량을 방지하는 것입니다. 이 단계에서 약간의 회전은 후속 용접 품질에 대비하기 위한 것이며 허용되지만 불필요한 대규모 회전은 최소화해야 합니다.

공식 가열 단계에 들어갈 때, 즉 PE 파이프 단부가 가열을 위해 고온 용융 다이에 연결되었을 때 파이프 또는 파이프 피팅을 회전시키는 것은 절대 금지됩니다. AD 파이프의 PE 파이프는 특정한 용해 지수와 열 안정성을 가지고 있습니다. 가열 시 용접 표면이 균일하게 가열되어 균일한 용융 링 이때 회전하면 고르지 못한 가열을 유발하고 용융층의 무결성과 균일성을 파괴한 다음 용접 강도에 영향을 미쳐 인터페이스 누출과 같은 안전상의 위험을 초래할 수 있습니다.

가열이 완료되면 다이 헤드에서 PE 파이프를 제거하고 신속하게 도킹을 수행하십시오. 이 "전환" 과정에서 파이프의 안정성은 외부 힘이나 자체 무게로 인한 회전을 방지하기 위해 유지되어야 합니다. 도킹 시 압력을 축 방향을 따라 부드럽고 고르게 가하여 두 개의 용융 엔드 면이 밀착되도록 해야 합니다. 이 프로세스는 또한 회전할 수 없습니다. 회전할 경우 형성된 용융층이 비틀리고 이동하여 용접 결함이 발생할 수 있습니다. 117277 전체 냉각 과정 동안 PE 파이프의 인터페이스에 안정적인 분자 사슬 구조가 형성되고 있습니다. 이때 파이프와 파이프 피팅이 완전히 고정되고 어떤 형태의 회전이나 움직임도 엄격히 금지되도록 해야 합니다. 약간의 회전이라도 냉각 및 굳어지고 있는 용접 조인트가 손상되어 인터페이스의 강도가 저하되고 전체 파이프라인 시스템의 압력 지지 용량 및 사용 수명에 영향을 미칠 수 있습니다.

AD 파이프는 PE 파이프의 고온 용융 연결 품질이 전체 파이프라인 프로젝트의 품질과 직접적인 관련이 있음을 상기시켜 줍니다. 사양에 따라 엄격하게 작동하고 "회전 가능 여부"의 핵심 노드를 파악하는 것이 용접이 견고하고 시스템이 안전 작동 사양에 대해 질문이 있는 경우 AD 파이프라인에서 제공하는 공식 시공 지침을 참조하거나 전문 기술자와 상의하여 각 용접 조인트가 표준을 충족하고 배관 시스템이 장기적으로 가장 잘 작동할 수 있도록 하는 것이 좋습니다
