أطواق الحفر هي مفصل ثقيل متكامل تم إنشاؤه من شريط صلب من AISI 4145H الصلب المعدلة. يتم تزويد أطواق الحفر القياسية لدينا مع حالة الانتهاء من السطح "كما هو مدفوف".؟ تتلقى جميع القضبان القياسية المعالجة الحرارية التي توفر لهم الخصائص الميكانيكية اللازمة.
ثم يتم تحطيم القضبان والانجراف.؟ يتم تصنيع جميع أطواق الحفر الخاصة بنا وفقًا لمواصفات API 7 و Q1 والممارسة الموصى بها 7G ، حسب الاقتضاء. ASTM A519 أنبوب الصلب ASTM A213
