1 / 4 Duplex 2205 Stainless Steel Corrosion Resistant Coiled tubing ASTM A789

2205 duplex stainless steel is a kind of stainless steel in which the proportion of ferrite phase and austenite phase in solid quenching is half and half, which is short for 2205 stainless steel. The actual phase ratio is ferritic 45~55% and austenite 55~45% accordingly. Excellent performance of 2205 duplex stainless steel depends on the appropriate proportion of the two-phase structure to ensure. 2205 duplex stainless steel tubes have excellent mechanical properties and corrosion resistance, as well as good weldability, and are widely used in the petroleum and natural gas industry, Marine engineering, chemical industry and other industries.

Duplex SS 2205 Corrosion-resistant coiled 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.

Our products have complete specifications and can meet all working conditions. Our outer diameter range of 2205 tube is from 1/8” to 1/2”. All dimensions and corresponding parameters are listed in the table below, we can also customize it according to customers' special requirements.

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

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.
