1 / 8 ASTM A789 Downhole Chemical Injection Tubing Duplex 2205 Bright Annealed

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 production process is exquisite, the technology is mature, the product conforms to the international standard, already obtained the home and abroad customer's high recognition.Our control line tubing material has low content of sulfur and phosphorus, uniform structure, and suitable mechanical properties. All mechanical properties are in accordance with ASTM Standard. Using high quality raw materials and laser welding technology, our products have the characteristics of high strength, high plasticity, low cycle fatigue performance, high efficiency, low cost, ety and environmental protection.

2205 is a duplex (austenitic-ferritic) stainless steel containing about 40 - 50% ferrite in the annealed condition. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless.

Duplex SS 2205 Corrosion-resistant control line tubing is one of our most competitive products, we have rich processing and supply experience. Our products are standardized and international, complying to ASTM A789 and all relevant industry standards, and have been exported to overseas markets in large quantities for many years.

Application:

ety critical hydraulic control of sub surface ety valves

Subsea control lines

Downhole control and monitoring in intelligent well completions

Chemical injection using acids, surfactants and methanol

Coiled control line tubing is also used in onshore or topside hydraulic and instrumentation systems where the longer coils result in fewer connections and can increase the integrity of the overall system.

We have a mature quality control system to ensure a 100% qualified delivery rate:

Chemical composition analysis

Tensile testing

Hardness

Flattening

Flaring

Hydrostatic testing

Eddy current testing

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.
