PE管の溶接温度は何ですか?

2025-08-19

PEパイプは、給排水、ガス輸送などの分野で広く使用されているプラスチックパイプの一種であり、その溶接品質は、パイプラインシステム全体の安全性と耐用年数に直接関係しています。溶接プロセスの重要なパラメータとして、溶接温度は、しっかりとしたインターフェースと漏れのないことを保証するためのコア要素の1つです。

通常の状況では、PEパイプの溶接温度は、原材料のグレードと特定の製品特性によって異なります。一般的なPE 80およびPE 100レベルのPEパイプの場合、推奨される溶接温度は一般に200℃〜230℃です。実際の操作では、この温度範囲を厳密に制御する必要があります。温度が高すぎると、パイプの溶接面に炭化や劣化などの問題が発生し、溶接強度やシール性能に影響を与える可能性があります。温度が低すぎると、溶接が不十分になり、

溶接温度に加えて、加熱時間、ドッキング圧力などのパラメータも同様に重要であり、これらが組み合わさって完全な溶接プロセスシステムを構成します。プロのパイプラインメーカーとして、ADパイプラインは常に標準化された建設の重要性を強調してきました。AD PEパイプを溶接する場合は、製品マニュアルまたは関連する技術仕様を参照し、パイプの直径、壁の厚さ、およびその他の要因を組み合わせて、合理的な溶接パラメータを設定することをお勧めします。同時に、標準に準拠したホットメルト溶接装置を使用し、装置が正常に動作し、加熱プレートが清潔であることを確認してください。

溶接前に、パイプポートを清掃および成形し、酸化物層と不純物を除去し、接合面が平坦であることを確認する必要があります。溶接プロセス中、オペレーターは溶接が完了したら、外力の干渉を避けるために規則に従って冷却する必要があります。インターフェースが完全に冷却および固化した後、フォローアップの建設を行うことができます。

要するに、PEパイプの溶接温度および関連するプロセス要件を正確に把握することは、パイプラインシステムの長期的な安定した動作を保証するための基礎です。ADパイプのような信頼性の高い品質のPEパイプ製品を選択し、科学的な溶接プロセスに厳密に従うことによってのみ、不適切な溶接によって引き起こされる隠れた工学的危険を効果的に回避し、さまざまな種類の流体輸送プロジェクト
