Abstract

يتم توفير وصلة ملولبة threaded joint لمواسير فولاذية قادرة على تحسين الأداء المضاد للكلال anti-fatigue مع ضمان مقاومة التخدش )اهتراء المعادن بالاحتكاك( galling resistance. تتضمن الوصلة الملولبة مسمار pin وصندوقbox . يتضمن المسمار جزء حز اللولب البارز male thread part (11) مستدقtaper ، ويتضمن الصندوق جزء حز اللولب الغائر female thread part (21) مستدق ليتم تعشيقه مع جزء حز اللولب البارز male thread part (11) المستدق. ينقسم جزء حز اللولب البارز male thread part (11) إلى منطقة أولى first region (15) على جانب الطرف الحر من المسمار، ومنطقة ثانية second region (16) على الجانب الأنبوبي للمسمار بطول اتجاه (CL) لمحور الأنبوب. تكون نسبة الاستدقاق taper ratio (Tp1) للمنطقة الأولى first region (15) أكبر من نسبة الاستدقاق (Tp2) للمنطقة الثانية second region (16). تكون نسبة الاستدقاق (Tp1) للمنطقة الأولى first region (15) أكبر من نسبة الاستدقاق (Tb) لجزء حز اللولب الغائر female thread part (21). تكون نسبة الاستدقاق (Tp2) للمنطقة الثانية second region (16) مساوية أو أكبر من نسبة الاستدقاق (Tb) لج
