ASTM A269 Cold Drawn Capillary Coiled Tubing

We specialize in stainless steel coiled tubing for years, having facility to producing superior coil tubing, with a varieties of sizes and dimensions.

Welded coiled tubes and seamless coiled tubes are both offered as standards, common specification is ASTM A269, cold drawing manufacturing process improve tubing performance, annealing pickling and bright annealing finishes are for specific uses.

After straight tubing finished, tubing is coiled, and slightly formed circle shape into a reel, maximum length up to 1000 meters.

Stainless steel is a large group with good corrosion resistance, meanwhile, the material have perfect toughness and formability under annealed condition, which properties made tubing easy to fabricate and bending.

We specialize in manufacturing small diameter tubing ranging from 0.125 inch to 1 inch outer diameter (3.2 mm to 25.4 mm) and a variety of wall thicknesses.

All tubing can be coated with PVC or TPU providing additional protection against the elements and line identification.

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.
