ASTM A269 316L Downhole Chemical Injection Tubing Hydraulic Control Line
Control lines usually are coiled tubes made of stainless steel, duplex stainless steel or nickle alloys. The coiled tubes mostly are welded & redrawn tubes or seamless cold drawn tubes. Control lines are usually supplied with very long continuous lengths coiled on the drums.
As the professional manufacturer of control lines, we produce control line tubing in material stainless steel 316L, duplex stainless steel 2205, 2507, Nickel alloy 825 & alloy 625.
Besides the above, we also make control line tubes with other materials upon customers’ request.
Control Lines Size Range
Outer Diameter (OD): 3 mm (0.118”) to 25.4 mm (1.00”)
Wall Thickness (WT): 0.5mm (0.020”) to 3mm (0.118”)
OD tolerance +/- 0.005” (0.13mm) , other tolerances are available on request
WT tolerance +/- 10%, other tolerances are available on request
Tubing Coil lengths up to 6,000m (20,000ft) without orbital joints depending on product dimensions and its form (seamless tube or welded tube).
Coil lengths up to 13,500m (45,000ft) with orbital joints
Control lines are broadly applied in many applications, such as below:
Downhole hydraulic control lines
Downhole chemical control lines
Subsea control lines for hydraulic power and chemical injection line
Flowline control
Instrumentation tubing
Smooth inner surface control line tubing used in fibre optic applications
