Duplex 2507 Geothermal Coiled Capillary Tubing
MEILONG manufactures Seamless Corrosion Resistant Alloy (CRA) Hydraulic Control Line Tubing products for a variety of upstream oil and gas and geothermal applications. MEILONG has extensive experience in producing coiled tubing from duplex, nickel alloy and stainless steel grades to industry and customer-specific requirements.
Control line tubing is available in lengths from 400 feet (122 meters) to 32,808 feet (10,000 meters). Long lengths are possible by utilizing a combination of strip splice and tube-to-tube orbital welds.
Diameters range from 0.125 inches (3.18 millimeters) to 1.75 inches (44.45 millimeters), with wall thicknesses up to 0.160 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 alloy tubing for chemical injection
- Bare and encapsulated hydraulic control line coiled alloy tubing for subsea safety valves
- Velocity strings, work strings, and steel tube umbilicals
- Geothermal coiled alloy tubing
