Neonox Duplex Steel S31803 pipe fittings are manufactured using a balanced combination of austenitic and ferritic microstructures, offering excellent strength and corrosion resistance. These fittings are available in two main types—seamless and welded—each designed to meet specific industrial requirements.
Seamless fittings are produced without joints or welding seams, providing enhanced strength and superior resistance to corrosion, making them ideal for critical applications. Welded fittings, on the other hand, offer a cost-effective solution while maintaining reliable performance, making them suitable for a wide range of industrial uses.
