3 / 8 Inconel 625 Hydraulic Control Line tube Seamless Tubing ASTM B 704

3/8" INCONEL 625 hydraulic control line (coiled tube) is an austenitic super alloy with nickel as the main component. Due to the strengthening effect of molybdenum and niobium solid solutions contained in nickel-chromium alloy, it has ultra-high strength and special anti-fatigue properties from low temperature to 1093℃, and is widely used in oil & gas industry.

Although the alloy is designed to adapt to the high-temperature environment, the high content of chromium and molybdenum in the alloy has a high anti-corrosion spot and anti-fission corrosion capability for many corrosion media, from the high oxidation environment to the general corrosion environment, showing excellent corrosion resistance characteristics. INCONEL 625 also has strong corrosion resistance to chlorinated media such as sea water, geothermal water, neutral salts, and salt water. The corrosion resistance of INCONEL 625 is even comparable to that of secondary titanium and hastellian alloy C-276 through geothermal brine tests and simulated gas desulfurization environment tests.

In addition, the alloy has high formability and is easier to weld than many nickel-based alloys. The alloy is resistant to intercrystalline corrosion even when welded. It has good tensile and fatigue properties from low temperature to 980℃, and is resistant to stress corrosion under salt spray atmosphere.

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.
