316L SS Cold Drawn Seamless Control Line Tubing for oil and gas well

316L grade stainless steel, is the second most common austenitic stainless steel after 304 stainless steel. Its primary alloying constituents after iron, are chromium(between 16–18%), nickel(10–12%) and molybdenum (2–3%), with small (<1%) quantities of silicon, phosphorus & sulfur also present. 316L grade is the low carbon version of 316 stainless steel. When cold worked, 316 can produce high yield and tensile strengths similar to Duplex stainless grades.

316L SS Capillary tube coils are commonly used in chemical and petrochemical industry, pharmaceutical equipment, medical devices, in marine and subsea applications and architectural applications near the seashore or in urban areas.

We specialize in providing either welded or seamless hydraulic control lines for subsurface applications. Seamless hydraulic control line is available in length to 500 ft (152 m). Lengths greater than 500 ft (152 m) are joined by orbital welding, which also meets ASTM specification A-269.Our seamless control lines are used in SCSSV, Chemical Injection, Advanced Well Completions, and Gauge Applications.

Diameter from 3mm (0.118”) to 25.4mm (1.00”) OD

Wall thickness from 0.5mm (0.020”) to 3mm (0.118”)

OD tolerance +/- 0.005” (0.13mm) and +/- 10% wall thickness, other tolerances are available on request

Encapsulated, PVC coated or bare line tubing

Available on wooden or steel drums.

Our uniquely designed, high quality continuous length seamless stainless steel tubing helps to reduce installation time and is more reliable than coupling multiple shorter lengths with welds or mechanical fittings. Continuous length, seamless tubing significantly decreases the opportunity for defect, such as leaks and other long-term failures.

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.
