PE管は直接巻けますか?

2025-08-19

プラスチックパイプの設置と施工では、接続方式についての疑問がよく発生し、その中で「PEパイプは直接針金をかけることができますか」という問題が注目されている。答えは否定的で、PEパイプは通常、直接針金をかけることができない。

PEパイプ、すなわちポリエチレンパイプは、その材質特性が伝統的な針金接続技術を採用するのに適していないことを決定した。PEパイプは良好な柔軟性と耐食性を持っているが、同時にその剛性は比較的低い。針金接続はパイプの端部でねじを切る必要があり、この過程はPEパイプのパイプ構造に破壊をもたらし、パイプがねじに応力集中し、ひび割れ、漏れなどの問題を引き起こしやすい。また、PE管の熱膨張係数が大きく、被覆線接続は長期的なシール性能と構造安定性を確保することが困難であり、水圧や温度変化の作用下で接続部が緩みやすく、パイプラインシステム全体の安全な動作に影響を与えます。

PE管は直接被覆線を使用できないため、通常どのような信頼性の高い接続方法を使用しますか?現在、PE管の主流の接続方法には、ホットメルトドッキング接続と電気メルト接続が含まれます。ホットメルトドッキング接続は、2本のPE管の端部を溶融状態に加熱した後、すばやくフィットさせて加圧し、冷却後にしっかりとした全体を形成することです。この接続方法は、大口径PE管に適しており、接続強度が高く、シール性能が高く、施工が簡単です。電気溶融接続は、電気溶融管継手内部の抵抗線を通電して発熱させ、管継手と管材の接触面を溶融させ、両者の緊密な結合を実現する。電気溶融接続は、様々な口径のPE管に適用され、特に配管の緊急修理、管継手と管材の接続、複雑な条件下での接続に優れており、その接続品質は安定して信頼性が高く、人為的要因の影響を受けにくい。
