Application of Encapsulated Coiled Tubing


The tubing made from (duplex) stainless steels is not corrosion-resistant to all environments. The tubing performance is heavily influenced, as well as lifetime of tubing decreases.

The encapsulation is used as a protective layer for keeping metal tubing from various aggressive chemical environments. And to enhancing the corrosion resistance performance of the entire coiled tubing.
