316L Stainless Steel Coiled Tubing Corrosion Resistant 3 / 4 Standard ASTM A269

316L stainless steel (UNS S31603) has been widely used in industry due to its excellent corrosion resistance. As one of the most commonly used coiled tubing materials, our 316L tube has mature technology and exquisite workmanship. Starting from the raw material, we strictly control the performance of steel. Our products meet ASTM A269 and all related industry standards. Our tubing is one continuous length of tubing, completely free of any welded joints or seams. Each coil is 100% hydrostatic tested. Eddy current testing (ET) is performed on the longitudinally seam welded tubing. Radiographic testing and ET are performed on material in the final heat treated condition. Yield pressure hydrostatic testing is performed on the heat treated tubing at final size.

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.

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.
