Encapsulated hydraulic control line for subsea ety valves
The encapsulated tubing are designed to protect the (duplex) stainless steel tubing coils free from various harsh corrosion environments. Tube will be Encapsulated with high performance thermoplastic or elastomer materials functional in either 150C or 200C operating temperature environments.The tube size and encapsulation material can be made as per requirement, Flatpack is also available.
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.
Encapsulation materials:Santoprene,F40;F46;FEP (Fluorinated Ethylene Propylene);PVC (Polyvinyl chloride);Nylon Encapsulated etc..
Available Encapsulation shapes: Round Type, Square type, Flatpack
Coiled tubing is available in lengths from 100 feet (30 meters) to 100,000 feet (30,000 meters). Long lengths are possible by utilizing a combination of strip splice and tube-to-tube orbital welds.
Diameters range from .250 inches (6.35 millimeters) to 1.75 inches (44.45 millimeters), with wall thicknesses up to .160 inches (4 millimeters).
Specialized features can include cold working for higher yield strength, intrusion-free orbital welds and a minimized number of orbital welds. Tubing can be coiled onto IPPC-certified wood or metal reels customized to the users’ specifications.
Applications include:
Capillary Coiled Stainless Steel Tubing for chemical injection
Bare and encapsulated hydraulic control line coiled stainless steel tubing for subsea ety valves
Velocity strings, work strings, and steel tube umbilicals
Geothermal Coiled Stainless Steel Tubing
