Inconel Tube
Precision-grade Inconel tubes designed to endure high temperatures, mechanical strain, and corrosive conditions are produced and supplied by Stellanox Steel. These tubes, which are made of high-performance nickel-based alloys such as Inconel 600, 625, 718, and X-750, are intended for use in heat exchanger systems, high-temperature fluid transfer, and critical pressure applications in the nuclear, petrochemical, maritime, and aerospace sectors.
Our Inconel tubes satisfy the strictest international standards and are offered in seamless, welded, coiled, and U-bend configurations.
What are Inconel Tubes?
Inconel tubes are hollow, cylindrical metal objects derived from superalloys based on nickel and chromium. These tubes work particularly effectively in procedures that include a lot of chemicals, intense heat, and high pressure. Inconel tubing is used in nuclear reactors, jet engines, heat exchangers, and chemical reactors where failure is not an option because of its remarkable resistance to oxidation, crevice corrosion, and stress rupture.
