Product Description

Duplex 2205 Stainless Steel 1 / 8 " 0.035 ”hydraulic Control Line tubing


We are professional hydraulic control lines, Stainless Steel control line Tubes/tubings, Stainless Steel coiled control line Tubes/tubings manufacture from china.
The outer diameter of hydraulic control lines, Stainless Steel control line Tubes/tubing that we could do is in 1/8", 1/4", 1/2", 3/8", 3/4", 5/8",
The wall thickness hydraulic control lines, Stainless Steel control line Tubes/tubing that we could do is in 0.028", 0.035", 0.049", 0.065", 0.083"


Hydraulic Control Line is A small-diameter tube used to operate downhole completion equipment such as the surface controlled subsurface safety valve (SCSSV), is available in five materials, varying wallthicknesses, and a wide range of working pressure ratings. By manufacturing technique, hydraulic control line has 2 categories, Welded tube and Seamless tube.

Control line encapsulation also is available as per the customer requirement to provide additional crush and abrasion resistance during installation.


As the well configuration, completion technique and more wells workover come up, hydraulic control line demand has been dramatically increased, more demand comes from offshore Deepwater operation, which requires encapsulation and NAS6 cleanness hydraulic control line. On the other hand, new technologies are being introduced to the oilfield, like intelligent completion, this boost up hydraulic control line demand.


1/8" stainless steel control line tube is mainly used for controling the downhole safety valve and bleed valve of packer ,connecting 1/8 "hydraulic control line to downhole safety valve & bleed valve, through the ground pressuring given to control the switch of subsurface safety valve and bleed valve, after processing to the set pressure, subsurface safety valve and bleed valve will be opened at the same time, oil and gas Wells will be in proper production, at the same time, the gas separated by electric submersible pump can also be discharged by bleed valve, if encounter with blowout or normal well shut-in, then release the pressure of control line, so as to close the subsurface safety valve and bleed valve, Plugging the oil and gas well tubing and annulus flow channel to ensures the safety of oil Well, of course, the 1/8 "hydraulic control line can also be used separately for controlling subsurface safety valve, it also can be used for the control of the ground safety valve and other ground pressure control valve, as well as large equipment instrument control systems.


The control lines are used in the following applications:


Downhole hydraulic control lines;

Downhole chemical injection control lines;

Subsea control lines for hydraulic power;

Smoothbore control line used in fibre optic applications;
