PE管は火で焼くことができますか?

2025-08-19

現代の配管や地方自治体の建設では、PEパイプは、その優れた耐食性、柔軟性、経済性のために広く使用されています。しかし、建設中または使用中にPEパイプを焼くことができるかどうかは、多くのユーザーにとって懸念事項です。

PEパイプの主な材料はポリエチレンです。これは熱可塑性樹脂であり、耐熱性に優れていますが、この耐熱性は特定の温度範囲内です。通常、PEパイプの使用温度範囲は-20℃から40℃の間が推奨されます。温度が高すぎると、ポリエチレン材料は熱変形し、引張強度、剛性などの物理的および機械的特性が急激に低下します。

PEパイプを焼くと、短時間の高温接触でも、パイプが局所的に軟化して変形し、さらには溶けたり割れたりする可能性があります。これは、パイプの構造的完全性を破壊し、耐用年数に影響を与えるだけでなく、後の使用で水漏れなどの潜在的な安全上の問題を引き起こす可能性があります。特に圧力を必要とする一部のパイプラインシステムでは、焼成されたPEパイプの耐圧能力が大幅に低下し、大きな安全上のリスクがあります。

ADパイプは、プロのパイプライン製造企業として、通常の使用条件下での製品の安全性と信頼性を確保するために、国の基準に厳密に準拠しています。PEパイプの設置および接続プロセスでは、プロのホットメルト接続または電気メルト接続技術を使用する必要があります。これらの方法は、焼成などの不規則な手段ではなく、パイプ接続の密着性と強度を確保できます。

PEパイプを正しく使用するには、直火や高温環境にさらさないようにする施工中、PE管を屈曲などの操作が必要な場合は、それ自体の良好な柔軟性を利用して、常温で行うか、専用の工具や設備の助けを借りて、規範プロセスに従って操作する必要があります。

要するに、PE管は火で焼くことはできません。配管システムの安全で安定した運行を確保するために、正規のブランド、例えば西暦配管のPE管製品を選択し、製品の説明書と関連施工規範に厳格に従って設置と使用を行い、パイプの性能に影響を与える可能性のある不適切な操作を排除することをお勧めします。
