1 / 8 ASTM A269 Downhole Chemical Injection Tubing 304L Weled Control Line

Tiptop can supply various sizes of austenitic 304L stainless steel tube as shown 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.

TIPTOP manufactures precision control line tubing for hydraulic and chemical injection of onshore and subsea oil and gas wells. The control line tubing is manufactured in a number of different product forms including seam welded and redrawn, seam welded and floating plug redrawn and seamless depending on the customer’s specification and application. Our control line tubing products have been successfully used in some of the most aggressive subsea and downhole conditions and we have a long proven track record of supplying products that meet the strict quality requirements of the Oil & Gas sectors.

Austenitic stainless steel has good corrosion resistance, high temperature oxidation resistance, good low temperature performance and excellent mechanical and processing performance. Therefore, it is widely used in chemical, petroleum, power, nuclear engineering, aerospace, marine, pharmaceutical, light industry, textile and other sectors. Its main purpose is to prevent corrosion and rust. Corrosion resistance of stainless steel mainly depends on the surface passivation film. If the film is incomplete or defective, stainless steel will still be corroded. Pickling and passivation are usually carried out in engineering to make the corrosion resistance potential of stainless steel more developed. Stainless steel surface cleaning, pickling and passivation, in addition to maximize corrosion resistance, but also to prevent product pollution and aesthetic effect.

304L stainless steel control line tubing is a very common stainless steel tubing. Its corrosion resistance is better than 201 and 202. Due to its corrosion resistance and high temperature resistance and good processing performance, it is widely used in mechanical equipment, sanitary ware, fluid transport, chemical instruments, furniture decoration industry and food industry. Though the price of 304L is higher than that of 304 stainless steel, the carbon content of 304L is lower than 0.03%, which has good welding performance.

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.
