Product Detail

Competitive Edge: Why Double-Arm?

Optimized Load Distribution: The symmetrical dual-arm geometry is specifically designed to minimize rotational torque during high-tension hoisting. This ensures the elevator remains perfectly aligned with the wellbore, reducing uneven wear on drill pipe tool joints.
Engineered for Ultra-Deep Operations: In scenarios where load weights exceed standard limits, the Double-Arm configuration provides superior structural redundancy, making it the “Problem-solver” for the world’s most challenging offshore and deep-well environments.
Superior Grain Flow & Fatigue Life: Utilizing premium alloy steel and a proprietary swaged forging process, we ensure that the internal grain structure follows the link’s contours, significantly extending the service life under cyclical loading.

Manufacturing Integrity: The Weld-Strength Guarantee

Hybrid Manufacturing Process: Our Double-Arm links combine the raw strength of forging with the geometric precision of advanced welding. This ensures the link eyes and body are fused into a singular, high-intensity unit.
100% Non-Destructive Testing (NDT) Protocol: To guarantee zero-defect integrity, every welded joint undergoes a multi-stage verification:
- Magnetic Particle Inspection (MPI): Detects any surface micro-fissures.
- Ultrasonic Testing (UT): Verifies internal molecular consistency and fusion depth.
- Proof Load Testing: Every link is tested to 1.5x – 2x its rated WLL before dispatch.
