The tubing made from 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.
Sheathed control Line is made by duplex stainless steel, and sheathed by types of materials, such as:
FEP (Fluorinated Ethylene Propylene);
PVC (Polyvinyl chloride);
All encapsulated materials are hydraulically stable and are compatible with all usual well completion fluids, including high pressuer gas, and material selection is normally on the basis of bottom hole temperature-encapsulations are avialable for well temperatures up to 500°F.
Normally used for petrochemical applications, and keeping tubing free from various aggressive chemical, strengthening the performance of corrosion resistance for the coiled tubing. Our encapsulation material is capable to use under the high temperature of 280°C.
Metal Tubing: 304, 316L, 2205, 2207, 825, 625
Encapsulation shape: round, square, flat pack
