Downhole 0.083" ASTM B704 Capillary Incoloy 825 Tube

Alloy 825 High Precision Stainless Steel Capillary Coil Round Tube

Improvements in the technology for the enhanced exploitation of oil and gas fields has increasingly required the use of long continuous lengths of stainless steel and alloy tubulars for hydraulic control, instrumentation, chemical injection, umbilical and flowline control applications. The benefits of this tubular technology have resulted in reduced operating costs, improved recovery methods and reduced capital expenditure by connecting downhole valves and chemical injection with remote and satellite wells to a fixed or floating central operating platform.

The control line is 100% dimensionally inspected and eddy current tested to international ASTM or DIN standards. All lines are 100% hydraulically pressure tested before being released and certified. Any orbital joints are also radiographically tested in a minimum of 3 planes to ensure the quality of the joint.

Coiled tubing is available in a range of different product forms depending on customers' requirements. We specilize in providing seam welded and redrawn, seam welded and floating plug redrawn and seamless tube products. The standard grades are 316L, alloy 825 and alloy 625. Other grades of stainless steel in duplex and superduplex and nickel alloy are available on request. Tubing can be supplied in the annealed or cold worked condition.

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.
