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.

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.
