1 / 4 * 0.035 304L Seamless Hydraulic Control Line Tube ASTM A269

1/4" hydraulic control line is mainly used for the control of the well subsurface ety valve and cable packer relief valve. It will be connected to subsurface ety valve and air valve. Through changing the pressure on the ground, people can control opening and closing of the subsurface ety valve and cable packer valve in oil and gas well. When the pressure reaches a certain value, the subsurface ety valve and cable packer valve will open at the same time and then oil and gas wells can produce normally. At the same time, the gas from electric submersible pump can also be vented through the vent valve. In case of a blowout or normal shut-in, people just need to release the pressure of control lines, so as to make the subsurface ety valve and cable packer valve closed at the same time as well as well tubing and annulus flow channel plugged, which will ensure the ety of the well. The 1/4" hydraulic control line can also be used solely for subsurface ety valve control. It can also be used for pressure control of surface ety valve and other surface valves, as well as various connecting lines of instrument control system for oil and gas field drilling and oil production large-scale equipment.

For 1/4" hydraulic control line, Tiptop can provide wall thickness of 0.02", 0.028" and 0.035", 0.049", 0.065" and 0.083", made from Austenitic steel 304L (UNS S30403), Austenitic steel 316L (UNS S31603), Duplex 2205 (UNS S32205 & S31803), Super Duplex 2507 (UNS S32750), Incoloy 825 (UNS N08825) and Inconel 625 (UNS N06625). All control lines comply with ASTM-A 269, ASTM-A 632, ASTM-A 789 and ASTM-B 704. The range of working pressure to adapt is 60-120 Mpa. The control line can be customized for customers according to their requirements of length. In addition, 1/8", 3/16", 5/16", 3/8" and 1/2" of outside diameter are also our main lines shown as below.

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.

With the leading direction of producing High pressure extra long stainless steel control line tube(stainless steel coiled tubes), TIPTOP has become a high-tech industrial company integrating domestic research and development, production and sales. The company successfully developed a series of stainless steel testing cables in 2000. In recent years, the company has been committed to the research and development of duplex steel and nickel alloy control lines, and has been widely approved in the international market.

The company covers an area of 20,000 square meters and a building area of 12,000 square meters. The company has several stainless steel tube production lines, tube making units, tube drawing units, well-type electric furnaces, online vacuum light furnaces and other production equipment. The company also has a quality inspection center that meets the national stainless steel tube quality inspection requirements. The quality inspection center has a 300Mpa hydraulic test machine, tensile test bench, Vickers hardness tester, 500°C temperature resistance test furnace, eddy current flaw detector and a series of stainless steel products. Testing and inspection equipment to ensure the reliability and stability of the chemical and physical properties of stainless steel products.　

The company annually produces more than 3,000 tons of stainless steel control lines and other products, sales marked covers both domestic and overseas, for domestic, we are network-enterprise company of CNOOC, Petro China and Sinopec, as for international,it has been widely used in Middle East, Southeast Asia, South America, Australia and so on.　

On the premise of improving the quality of its own brand products, the company has continuously increased the research and development of new products, and has cooperated and actively invested with many domestic universities and scientific research institutions. In recent years, the company has passed the certifications of CCS, GL, DNV and other classification societies.
