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

Available Alloy Grades for Control Line Tubing
Austenitic: 316L

Coiled Tubing Dimension
Outside Diameter: 1/8’’ – 1/2’’ (3.175 mm – 12.7 mm)
Coiled tubing length: up to 32,808 feet (10,000 m)
Tubing with minimum orbital welds reduces the risk of leakages when connecting tubes, and suitable for delivery for customers need.
Single coiled tubing is available
The tubes are delivered with plastic caps for protection from potential contamination during storage.

Packing
Coiled tubing is level wound on the spool/reel
Metal reels and marking can be specified by the customer

Application
Control line
Chemical injection line
Electrical line
Multi-line flat pack
Hydraulic line
Tubing encapsulated conductor
Intelligent well completions
