The next generation of coiled tubing
BlueCoil™ technology is a new, industry changing technology designed to expand the capabilities of coiled tubing and raise the operational quality and performance to the next level. It is also a technology platform for extending coiled tubing capabilities and reliability to meet future extreme operational demands. BlueCoil™ technology is based on new steel designs and new manufacturing processes 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 welds. 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, limiting 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, allowing greater utilization of the entire string, bringing additional strength, reliability and longer string life for coiled tubing applications.
BlueCoil™ technology is backed by Tenaris’s decades of experience and research in pipe manufacturing and metallurgy. BlueCoil™ products have undergone comprehensive testing to validate their advanced metallurgical, mechanical, fatigue and environmental performance. Field experience has confirmed quantifiable benefits of BlueCoil™ products in real-life operations.
BlueCoil™ technology provides extra strength and longer string life.

To create BlueCoil™ technology Tenaris developed new steel chemistries and new welding and heat-treatment processes that are exclusive for coiled tubing (patents pending.) They were designed to obtain higher strength grades and provide significant improvements in fatigue performance and sulfide stress cracking (SSC) resistance.
Most of the conventional coiled tubing properties are obtained when the flat strips are manufactured at the steel mill. The optimized microstructure and properties of the original flat strip material are later degraded in the bias and seam weld areas.
An innovative manufacturing process
On the contrary, the final properties of a BlueCoil™ string are obtained at the last stage of the manufacturing process. As a result, there is an improved microstructure and more uniform material properties across the entire string, including the bias and seam welds.

BlueCoil™ technology brings improved fatigue performance over conventional coiled tubing grades. This benefit extends to the bias welds, as they have the same improved microstructure as the base tube. In conventional coiled tubing, the shorter fatigue life of the bias weld limits the
useful life of the entire string. With BlueCoil™ technology, the fatigue life of the bias weld is similar to that of the base tube.
BlueCoil™ products resist ballooning better than conventional coiled tubing, making them ideal for high-pressure applications.

Extensive testing shows that fatigue performance of BlueCoil™ products after sour (aqueous H2S) exposure is markedly improved when compared to conventional coiled tubing grades. Additionally, fatigue life of conventional coiled tubing grades after sour exposure decreases as the coiled tubing’s yield strength increases. BlueCoil™ technology enables a more effective and more reliable usage of higher yield strength grades, as the sour fatigue life of BlueCoil™ grades did not show to be adversely affected by yield strength increases.
With BlueCoil™ technology, the performance of the bias weld in sour fatigue is very similar to the performance of the base tube. The improved and homogeneous microstructure of BlueCoil™ products results in significant sour fatigue improvements for both the base tube and bias welds. In conventional coiled tubing, bias welds typically fail in sour fatigue much sooner than the base tube, even for the lower-strength grades.

BlueCoil™ technology shows improved 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.
BlueCoil™ products are compatible with the
equipment currently used with conventional coiled
tubing, so there is no need for special handling or
equipment requirements.
This includes injector handling under high pull
load, BhA connectors and Bop shear and slip
performance.
