Encapsulated Stainless Steel Coiled Tubing Application
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.
