Duplex Steel S31803 / S32205 Instrumentation Tube Fittings

Duplex Stainless Steel Instrumentation Tube Fittings, UNS S31803 / S32205 Compression Tube Fittings, SAF 2205 Tube Fittings, Duplex Steel Single & Double Ferrule Tube Fittings, DIN 1.4462 Tube Fittings, Duplex Tube Fittings Manufacturer & Exporter in India

Rajgranth Industries PVT LTD is a prominent manufacturer and global supplier of Duplex Steel S31803 / S32205 Instrumentation Tube Fittings, known for their exceptional strength, superior corrosion resistance, and dimensional accuracy. These precision tube fittings are engineered for high-performance fluid and gas connections in industries such as oil & gas, chemical processing, power generation, and marine applications.

The duplex steel grades UNS S31803 and UNS S32205 (equivalent to DIN 1.4462 and SAF 2205) feature a balanced austenitic-ferritic microstructure that offers high mechanical strength, improved fatigue resistance, and exceptional performance in chloride-rich or corrosive environments. Our Duplex Instrumentation Fittings are available in various types, including male and female connectors, bulkhead connectors, male and female elbows, male run tees, branch tees, reducer unions, union crosses, NPT male adapters, BSPT couplings, BSPP plugs, and specialized components such as RPC (Reducer Port Connector), front ferrules, and back ferrules.

We manufacture both single ferrule and double ferrule instrumentation fittings with tight dimensional tolerances for easy installation, reusability, and leak-tight performance under cyclic loading, sub-zero temperatures, or dynamic pressures. Duplex Steel S31803 offers high ductility and stress corrosion resistance, while Duplex Steel S32205 provides enhanced thermal stability and higher work hardening rates, making both grades suitable replacements for traditional austenitic stainless steel in critical systems.

Choose Rajgranth Industries PVT LTD for premium-quality Duplex Steel S31803 / S32205 Instrumentation Tube Fittings that deliver exceptional performance, long service life, and unmatched reliability across industrial sectors worldwide.
