الوصف

The Double Shoulder Drill Stem is engineered for delayed coking applications, featuring advanced connection geometry with a positive torque stop and optimized thread profile to address the limitations of conventional threaded stems. The design improves fatigue performance and resistance to high cyclic loading in severe service. Features and benefits: - 10% Stiffer Pipe for improved rigidity, directional control, and fatigue resistance - 4X Make‑Up Torque Capacity with maintained tension across the entire threaded section - 3X Thread Engagement for enhanced connection integrity - Increased corrosion allowance with the cross-section area thickness enlarged, the assembly supports extended period before the wear and corrosion can compromise the joint - Better resistance to regular pressure cycles
