1 / 2 ASTM A789 2205 Duplex Stainless Steel Capillary Tube Capillary Coiled tubing

The 2205 duplex stainless steel standard no.: ASTM A240/A240M--01. It is composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local resistance to stress corrosion. The high yield strength of 2205 duplex stainless steel makes itself light, boasting a price advantage over 316 and 317 L. It is particularly suitable for temperatures in the -50°F/+600°F range.

The 2205 duplex stainless steel capillary tube can be produced into heat exahanger tube for petrochemical, chemical and ocean development fields, heater tubes, condenser tubes, sulfuric and phosphoric acids tubes, API tubes. It also can be used for gas turbine and prochemical processing as well as construction and ornament.

Tiptop offers a variety of duplex stainless steel, super duplex stainless steel welded and seamless tubing, depending upon the properties the tubing is required to exhibit. Other alloys and sizes are also available upon request. Duplex stainless steels (named for their austenite and ferrite compositions), has greater yield strength than austenitic stainless steel.

Standard: ASTM-A 789 Standard specification for seamless and welded ferretic/austenitic stainless steel tubing for general service. This specification covers various grades of duplex stainless steels.

The specification and length per coil can be customized according to customer’s requirements.

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.
