PE管の規格は外径ですか?

2025-08-19

PE管の仕様は外径ですか?今日、私たちはこの問題を詳細に検討し、西暦パイプのPE管製品と組み合わせて、PE管の仕様を明確に解釈します。

まず最初に明確にする必要があるのは、PE管の仕様は通常、その外径を主な識別パラメータとしていることです。ここでいう外径は、正確には公称外径で、記号「de」で表され、単位はミリメートル(mm)です。例えば、私たちはよくde 20、de 32、de 50、de 110などのPE管と言って、その数字はPE管の公称外径寸法を表している。このような外径を規格基準とする方式は、PE管業界で普遍的に採用されている基準で、これは主にPE管が熱溶融接続や電気溶融接続方式を採用しているため、外径の一貫性は接続品質を保証するために重要である。

西暦パイプは専門のパイプ生産企業として、生産したPE管はこの業界規範に厳格に従っている。西暦PE管の製品標識には、公称外径(de)を明確に表示するほか、通常、パイプの肉厚、圧力等級(SDRシリーズやPN値など)などの重要なパラメータが含まれているため、ユーザーは具体的な工事ニーズに応じて正確に選択することができる。たとえば、完全に識別されたAD PEパイプは、「PE 100 de 110 SDR 17 PN 1.6 MPa」と表示される場合があります。ここで、de 110はパイプの公称外径が110 mmであることを示し、SDR 17はパイプの外径と肉厚の比を反映し、PN 1.6 MPaは公称圧力を表します。

もちろん、外径を知るだけでは十分ではありません。PEパイプの肉厚も、その耐圧能力と使用範囲を決定する重要な要素です。同じ外径の下で、異なる肉厚のPEパイプは異なる圧力等級に対応します。ADパイプは、都市給水、農村飲料水、下水排水、ガス輸送など、さまざまなアプリケーションシナリオに応じて、さまざまな肉厚と圧力等級のPEパイプ製品を提供し、各製品が対応するエンジニアリングの安全性と性能要件を満たすことができるようにします。

以上のことから、PE管の仕様は実際には主にその外径(公称外径)で表され、これは業界の統一基準であり、設計、施工と選定の環節のコミュニケーションと操作を便利にしている。ADパイプは常に高い基準、厳しい要求を堅持し、PE管の生産と標識に明確で正確で、大多数のユーザーに信頼できる製品と専門的なサービスを提供するよう努めています。PE管の仕様選択について、その他のご質問がある場合は、いつでもADパイプにご相談ください。より詳細な回答とサポートを提供します。
