Tenaris will introduce its BlueCoil™ technology - the next generation of coiled tubing - at the annual Coiled Tubing and Well Intervention Conference and Exhibition on March 24-25 at the Woodlands Waterway Mariott Hotel and Convention Center.

BlueCoil™ technology is based on new steel designs and new manufacturing processes developed by Tenaris to produce coiled tubing that is stronger and more fatigue and environmentally resistant throughout its structure.

The life of a conventional coiled tubing string is normally limited by the fatigue life of its bias weld. As the required yield strength of coiled tubing increases, the fatigue life of the conventional bias weld decreases relative to the rest of the coiled tubing string. This limits the useful life of the entire string to the shorter life of the bias weld.

In contrast, the bias weld and base tube fatigue performance of a BlueCoil™ string remain comparable for high strength coiled tubing grades. This allows greater utilization of the entire string and brings additional strength, reliability and longer string life to coiled tubing applications.

BlueCoil™ technology brings extra fatigue performance and ballooning resistance over conventional coiled tubing grades. Fatigue performance of BlueCoil™ products after sour (aqueous H2S) exposure is also markedly improved.

Tenaris was the first coiled tubing manufacturer in the world to earn API 5ST certification, setting a new industry standard for manufacturing and testing of coiled tubing.  The arrival of BlueCoil™  technology reinforces Tenaris’s mission of delivering value to its customers through product development backed by decades of experience in metallurgy.
