1 / 4 * 0.065 Stainless Steel ControL Line Tubing 316L ASTM A269

Our products are employed in a variety of applications including hydraulic controls, instrumentation, chemical injection, umbilicals and flowline control.

In addition, regular inspections are performed at each mill and all tubing is inspected thoroughly prior to shipping. Hydrostatic test and other technical documents are available for all products.

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.

We has been providing stainless steel control lines with high quality & high pressure & super long all over the world for many years. Our stainless steel control tubes range in size from OD:0.125” to 0.625” (3.18mm ~ 15.86mm). Wall thickness varies between 0.028” and 0.065”. (0.711mm ~ 1.651mm).

1/4”Hydraulic control line, mainly used for the control of downhole ety valve and gas release valve of cable packer in oil and gas wells. The 1/4 “hydraulic control tubeline is connected to the downhole ety valve and gas valve, and the on-off pressure of the oil and gas well downhole ety valve and the gas release valve through the cable packer are controlled by ground pressure. After the set pressure is reached, the oil and gas well is downhole. The ety valve and the gas release valve passing through the cable packer are opened at the same time. At this time, the oil and gas well can be normally produced, and the gas separated by the electric submersible pump can also be discharged from the annulus through the gas release valve. Then, the pressure of the control tubeline is released, so that the downhole ety valve of the oil and gas well and the gas release valve passing through the cable packer are closed at the same time, and the oil and gas well oil tubes and annulus circulation channels are all blocked, so that the ety of the oil well can be ensured. Of course, the 1/4” hydraulic control line can also be used alone for the control of downhole ety valves.

It can also be used for pressure control of surface ety valves and other surface valves, and various connection tubelines of large-scale equipment instrumentation control systems for oil and gas field drilling and oil production.
