Adinox Overseas is a leading supplier and exporter of premium Nickel 201 Tubes, intended for challenging industrial purposes to withstand the demands of high corrosion resistance, good thermal conductivity, and lower carbon content. UNS N02201 classified Nickel 201 is a commercially pure wrought nickel with a 0.02% maximum carbon composition. This is the lower carbon version of Nickel 200 specifically developed to avoid intergranular carbon-induced embrittlement at high temperatures. It is also in line with international standards, specifically ASTM B161, with good mechanical properties and long-lasting functioning.
Our Nickel 201 Tubes are used in a wide range of industries that include dealing in caustic alkalis, chemical processing with high-purity, manufacturing of electronic components, and aerospace technology. The key advantage of Nickel 201 is its resistance to neutral and alkaline solutions of salts, and thus is best suited for applications in corrosion-prone conditions of equipment. Besides this, the tubes do not lose their ductility and strength at elevated temperatures, providing uniform service in heat exchangers, evaporators, pressure vessels, and reactors.
At Adinox Overseas, we provide Nickel 200 seamless tubes and welded tubes that are manufactured with the most advanced processes and rigorous quality control systems. Our tubes have superior dimensional accuracy and surface finishing, suitable for the most demanding high-pressure as well as low-pressure applications. We provide tubing suitable for applications in condensers, heat exchangers, evaporators, and reactors—our tubes last and perform with consistency.
Adinox Overseas supplies Nickel Alloy 201 Tubes in seamless, welded, ERW, and fabricated tube form, each carefully designed to suit different applications. Seamless Nickel 201 tubes are used where high-purity is demanded because of the uniform grain structure, whereas welded tubes serve as an affordable solution for structural and lower-pressure applications. All the tubes are made in line with stringent quality control using processes such as ultrasonic testing, chemical analysis, mechanical property testing, and third-party inspection, as needed.
The lower carbon content of Nickel 201 Tubing minimizes the possibility of precipitation of graphite at higher temperatures, and therefore, is especially well suited for temperatures above 315°C (600°F). Its good electrical and thermal conductivity make it ideal for electrical applications and thermal systems. Adinox Overseas ensures that its Seamless tubes of Nickel 201 and Welded tubes adhere to ASTM B161 and other international standards such as ASME SB161, DIN, and EN standards.
