Super Length Stainless Steel Control Line, 304L/316L 1/4'', 3/8''
Tiptop stainless steel 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.
Our leading products are stainless steel control line with high pressure and super length. Stainless steels exhibit excellent forming and welding characteristics. Stainless steel seamless coiled tubing final surface is bright annealed.
1/4" stainless steel control line tube is mainly used for controlling the downhole safety valve and bleed valve of packer. Connecting 1/4 "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 1/4 " 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.
