In this video, Tenaris shows how its next generation of coiled tubing, BlueCoil, works.
Tenaris based its BlueCoil technology on new steel designs and manufacturing processes developed by the company to produce coiled tubing that is stronger, more fatigue, and environmentally resistant throughout its structure.
Tenaris says that its 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.
The company has seen improved sulfide stress cracking (SSC) performance, allowing the use of 20 ksi to 30 ksi higher yield strength grades in SSC environments compared to conventional coiled tubing grades. Hydrogen induced cracking (HIC) tests show that all the coiled tubing grades, including conventional and BlueCoil technology, have good HIC resistance for sour conditions, according to Tenaris.
