Duplex Tube Fittings manufactured by New Eagle Industrial Corporation are components known for their durability, strong resistance to corrosion and reliable performance in various situations. Crafted from Duplex steel these fittings provide connections and great versatility across a wide range of industrial environment.


The unique chemical composition of Duplex Stainless Steel sets it apart. This type of steel is a blend of proportions of austenite and ferrite giving it the name "Duplex". Common grades like 2205 typically consist of 22% chromium, 5% nickel, 3% molybdenum and nitrogen. This balanced mix of elements gives Duplex Tube Fittings excellent corrosion resistance that surpasses austenitic stainless steel grades.


The exceptional mechanical properties of SDSS Industrial Tube Fittings make them a preferred option in various scenarios. With double the strength compared to stainless steel variants these fittings boast high tensile and yield strength to endure high pressures and temperatures. Despite their robustness they also exhibit ductility and toughness standing up to stress corrosion cracking in challenging environments.


These Super Duplex Steel Imperial Tube Fittings are widely used in the oil and gas sector due to their durability and resistance to corrosion. Specifically crafted for environments with chloride levels like offshore settings they also play a crucial role in the chemical processing industry. By enhancing safety and reliability these fittings prevent leaks in high pressure conditions. They are utilized across industries such as pulp and paper power generation, water desalination and in constructing components.


New Eagle Industrial Corporations Duplex Tube Fittings have gained a reputation for their performance and reliability through engineering making them a dependable ally in navigating complex industrial challenges.
