New Eagle Industrial Corporation supplies high-performance Duplex Stainless Steel Coiled Tubes engineered for demanding applications where superior strength, corrosion resistance, and long-term reliability are essential. Manufactured in seamless and welded forms, our Duplex coiled tubes meet ASTM A789/A790 standards and deliver excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich and aggressive industrial environments.Duplex stainless steels such as UNS S32205 (2205) and UNS S31803 offer a balanced austenitic-ferritic microstructure that provides higher yield strength than conventional stainless steels while maintaining excellent corrosion performance. This combination makes Duplex coiled tubes ideal for heat exchangers, instrumentation systems, chemical injection lines, hydraulic circuits, and offshore processing equipment. Their enhanced fatigue strength and pressure-handling capability allow for safe use in high-stress, high-temperature, and corrosive service conditions.Every Duplex coiled tubing produced with strict dimensional accuracy and surface finish control to ensure consistent performance and long operational life. Our tubes are available in long continuous coils, tight tolerances, and custom sizes to match specific project needs. All products are supplied with complete Mill Test Certificates (EN 10204 3.1) depending on the product type.
