About Duplex Steel UNS S31803 Instrumentation Fittings

Duplex Steel UNS S31803 Instrumentation Fittings are characterized by their lasting strength and increased resistance to corrosion. These components boast an impressive chemical composition of chromium, nickel, nitrogen, molybdenum, and manganese, each imparting its unique properties. Chromium provides superior corrosion resistance, while nitrogen boosts the steel's mechanical strength and austenitic microstructure. Molybdenum improves pitting resistance and further enhances the material's resistance to corrosion, making it ideal for use in high-pressure applications deemed prone to wear and tear.

Superior Corrosion and Pressure Performance

Engineered from Duplex Steel UNS S31803, these instrumentation fittings display excellent resistance to chloride-induced corrosion and oxidizing environments. Their robust design supports continuous operation up to 300C and withstands pressures up to 6,000 psi, ensuring safe and durable usage even in challenging industrial conditions.


Versatile Connection Types and Customization

These fittings accommodate an array of connection needs, from male/female threaded and tube-to-tube, to tube-to-pipe and compression end configurations. Customization is available for dimensions, thread standards, and shapes, ensuring compatibility with Swagelok, Parker, or bespoke systems while meeting exact project requirements.


Leak-Tight, Easy Installation Without Welding

Featuring advanced metal-to-metal and elastomeric sealing, the fittings provide leak-tight connections suitable for both vacuum and high-pressure scenarios. Thanks to their innovative design, installation is straightforward and requires no welding, minimizing downtime during assembly or maintenance.
