هل مواصفات أنبوب PE هي القطر الخارجي ؟

2025-08-19

عند شراء واستخدام أنابيب PE ، سيكون لدى العديد من المستخدمين أسئلة حول مواصفاتهم. أحد الأسئلة الشائعة هو: هل مواصفات أنابيب PE قطر خارجي ؟ اليوم ، سنناقش هذه المسألة بالتفصيل ، ونجمع بين منتجات أنابيب PE لأنابيب AD لتفسير مواصفات أنابيب PE بوضوح للجميع.

بادئ ذي بدء ، من الضروري توضيح أن مواصفات أنابيب PE تعتمد عادةً على قطرها الخارجي كمعامل تحديد رئيسي. القطر الخارجي المذكور هنا هو بالضبط القطر الخارجي الاسمي ، معبرًا عنه بالرمز "de" ، والوحدة ملليمتر (مم). على سبيل المثال ، غالبًا ما نقول أن أنابيب PE مثل de20 و de32 و de50 و de110 وما إلى ذلك ، تمثل الأرقام الموجودة فيها القطر الخارجي الاسمي لأنبوب PE. هذه الطريقة في استخدام القطر الخارجي كمرجع للمواصفات هي المعيار الشائع الاستخدام في صناعة أنابيب PE. ويرجع ذلك أساسًا إلى أن أنبوب PE متصل في الغالب بالذوبان الساخن أو الصهر الكهربائي ، كما أن اتساق القطر الخارجي أمر بالغ الأهمية لضمان جودة الاتصال.

AD Pipe كشركة مصنعة محترفة للأنابيب ، فإن أنابيب PE المنتجة تتبع بدقة مواصفات الصناعة هذه. عند تحديد المنتج لأنابيب AD PE ، بالإضافة إلى وضع علامة واضحة على القطر الخارجي الاسمي (de) ، يتم عادةً تضمين معلمات مهمة مثل سمك الجدار ودرجة الضغط (مثل سلسلة SDR أو قيمة PN) للأنبوب ، بحيث يمكن للمستخدمين إجراء اختيار دقيق وفقًا للاحتياجات الهندسية المحددة. على سبيل المثال ، قد يتم عرض أنبوب AD PE المسمى بالكامل كـ "PE100 de110 SDR17 PN1.6MPa" ، حيث يشير de110 إلى أن القطر الخارجي الاسمي للأنبوب هو 110 مم ، ويعكس SDR17 نسبة القطر الخارجي إلى سمك جدار الأنبوب ، ويمثل PN1.6MPa ضغطه الاسمي.

بالطبع ، لا يكفي مجرد معرفة القطر الخارجي. يعتبر سمك جدار أنبوب PE أيضًا عاملاً رئيسيًا في تحديد قدرة تحمل الضغط ونطاق الاستخدام. تحت نفس القطر الخارجي ، تتوافق سماكة الجدار المختلفة لأنابيب PE مع مستويات الضغط المختلفة. سيوفر AD Pipeline مجموعة متنوعة من منتجات أنابيب PE بسماكة الجدار ومستويات الضغط وفقًا لسيناريوهات التطبيق المختلفة ، مثل إمدادات المياه البلدية ، ومياه الشرب الريفية ، وتصريف مياه الصرف الصحي ، ونقل الغاز ، وما إلى ذلك ، لضمان أن كل منتج يمكنه تلبية متطلبات السلامة الهندسية والأداء المقابلة.

باختصار ، يتم التعبير عن مواصفات أنابيب PE بشكل أساسي من خلال قطرها الخارجي (القطر الخارجي الاسمي) ، وهو المعيار الموحد للصناعة ، مما يسهل الاتصال وتشغيل روابط التصميم والبناء والشراء. تلتزم AD Pipe دائمًا بالمعايير العالية والمتطلبات الصارمة ، وتسعى جاهدة لتحقيق الوضوح والدقة في إنتاج وتحديد أنابيب PE لتوفير منتجات موثوقة وخدمات احترافية لغالبية المستخدمين. إذا كانت لديك أسئلة أخرى حول اختيار مواصفات أنابيب PE ، فلا تتردد في الرجوع إلى AD Pipe ، وسنقدم لك إجابات ودعمًا أكثر تفصيلاً.
