Customized High Precision Duplex 2507 Hydraulic Coiled Tubing

2507 Super Duplex is a high-alloy duplex stainless steel with a PRE (Pitting Resistance Equivalent) value of minimum 42.5. The grade is characterized by very good chloride corrosion resistance, combined with very high mechanical strength. It is particularly suited for aggressive environments such as warm chlorinated seawater and acidic, chloride containing media. It is widely used in offshore oil and gas exploration and in heat exchangers in petrochemical processing. It's also suitable for hydraulic and instrumentation applications in tropical marine environments.

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.
