API 5 جغلاف صلب T (أوكتغ)
لدينا تم تصميم أنابيب غلاف API 5CT لتكون بمثابة التجنيب الهيكلي لـ جدران آبار النفط والغاز. مصممة لتحمل ضغط الانهيار الخارجي وقوة المحصول الداخلي ، تضمن هذه الأنابيب سلامة حفرة البئر خلال مراحل الحفر والإنتاج.
1. تكنولوجىمواصفات ايكال

التصنيع العملية: سلس (SMLS) أو المقاومة الكهربائية ملحومة (ERW)
2. API فولاذ 5CTدرجات
نحن توفير مجموعة كاملة من الدرجات مصنفة حسب القوة والبيئة المقاومة:
مجموعة 1:J55 ، K55 ، من من من
مجموعة 2 (محصول مقيد): من من من من من من من من ومن ومن ومن ومن ومن ومن ومن ومن ومن ثم
مجموعة 3 (قوة عالية):P110
مجموعة 4:Q125
3. Connectioن & أنواع خيوط
إلى ضمان أداء مقاوم للتسرب تحت ضغط عال ، ونحن نقدم معيار و اتصالات متميزة:
STC (غلاف خيطي دائري قصير)
LTC (غلاف خيطي طويل مستدير)
BTC (غلاف خيط دعامة)
قسط اتصالات: خيوط الغاز ضيق لأقصى الحدود بيئات خدمة عالية الضغط أو الحامض (H2S).
4. مفتاح أبليكاتيون المناطق
سطح غلاف: يحمي مناطق المياه العذبة ويدعم مانع الانفجار.
متوسط غلاف: يعزل مناطق الضغط العالي و تشكيلات غير مستقرة.
إنتاج غلاف: القناة النهائية للنفط والغاز الإنتاج ، وضمان الاستقرار على المدى الطويل بشكل جيد.
5. ضمان الجودة &حماية
الامتثال: الالتزام الكامل بأحدث إصدار من API Spec 5CT ؛ تم توفيره مع mtc (EN 10204 3.1).
الاختبار: ٪ NDT (الجسيمات بالموجات فوق الصوتية والمغناطيسية) ، الهيدروستاتيكي اختبار ، واختبار الانجراف.
سطح العلاج: اللوحة السوداء الخارجية/تتلاشى ، اللون الترميز وفقا لمعايير API.
التغليف: حزم فولاذية مربوطة مع واقيات خيوط (بلاستيك أو مركب) للنقل البحري الآمن.
