ASTM A269 316L Downhole Chemical Injection Tubing

Product Description

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

Others
