Tenaris presents its latest development, the BlueRod® premium sucker rods with a remarkably resistant connection designed for high loads. The connection improves the rod’s fatigue life and ensures excellent field performance.
- Flank-to-flank contact that eliminates the gap existing in the conventional profile thread and increasing the interference level, thus reducing the tendency to loosen.
- Cut-tapered trapezium profile thread with diametrical interference that reduces the pre-tension in the pin make-up.
- Lower displacement during make-up and uniform contact between the flanks, allowing a better stress distribution and a reduction in the permanent deformations created in threads during both make-up and operation.
