1 / 4 Stainless Steel Hydraulic Control Line Downhole Tube 316L ASTM A269

The control lines are used in the following applications:

Downhole hydraulic control lines;

Downhole chemical control lines;

Subsea control lines for hydraulic power and chemical injection;

Smoothbore control line used in fibre optic applications.

Hydrostatic test for each coil and conform to ASTM standards and requested specifications.

The specification and length per coil can be customized according to customer’s requirements.

Tiptop control line tubing products have been successfully used in some of the most aggressive subsea and downhole conditions and we have a long proven track record of supplying products that meet the strict quality requirements of the Oil & Gas sectors.

Improvements in the technology for the enhanced exploitation of oil and gas fields has increasingly required the use of long continuous lengths of stainless steel and nickel alloy tubing for hydraulic control, instrumentation, chemical injection, umbilical and flowline control applications. The benefits of this tubular technology have resulted in reduced operating costs, improved recovery methods and reduced capital expenditure by connecting downhole valves and chemical injection with remote and satellite wells to a fixed or floating central operating platform.

Coiled tubing is available in a range of different product forms depending on the customer requirements. We manufacture seam welded and redrawn, seam welded and floating plug redrawn and seamless tube products. Tubing can be supplied in the annealed or cold worked condition.

1/4" stainless steel control line tube is mainly used for controling the downhole ety valve and bleed valve of packer ,connecting 1/4 "hydraulic control line to downhole ety valve & bleed valve, through the ground pressuring given to control the switch of subsurface ety valve and bleed valve, after processing to the set pressure, subsurface ety 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 ety valve and bleed valve, Plugging the oil and gas well tubing and annulus flow channel to ensures the ety of oil Well, of course, the 1/4 "hydraulic control line can also be used separately for controlling subsurface ety valve, it also can be used for the control of the ground ety valve and other ground pressure control valve, as well as large equipment instrument control systems.
