غلاف النفط وأنابيب (أوكتغ) عملية الإنتاج
نحن نقدم مجموعة كاملة من أنابيب وأنابيب API 5CT ، بما في ذلك الدرجات الشائعة مثل J55 و K55 و N80 و L80 ، متوفرة مع وصلات قياسية (STC ، LTC ، BTC) أو وصلات متميزة لبيئات الحفر المتخصصة.
يتم تصنيع كل أنبوب وفقًا لمواصفات API 5L و API 5CT الصارمة ويخضع لمراقبة الجودة الداخلية الصارمة ، بما في ذلك الاختبارات الهيدروستاتيكية وغير المدمرة ، لضمان الموثوقية تحت ضغط قاع البئر.
نعم ، يتم تسليم جميع المنتجات بشهادة اختبار مطحنة (MTC) وفقًا لـ EN 10204 3.1 ، مما يوفر إمكانية التتبع الكامل للتركيب الكيميائي والخصائص الميكانيكية المطلوبة لمشاريع النفط والغاز.
