Supplier of duplex stainless steel instrumentation and compression tube fittings
Manufacturing Duplex 2205 instrumentation fittings and UNS S31803 duplex stainless steel compression tube fittings
Duplex Steel UNS S31803 Instrumentation Tube Fittings
Duplex ferrule fittings are used in instrumentation and tubing systems where a combination of strength and corrosion resistance is required. UNS S31803 Duplex Ferrule Fittings are available in various sizes, configurations, and dimensions to suit different project requirements. Duplex stainless steel provides improved resistance to corrosion along with higher mechanical strength, making these fittings suitable for long-term service in demanding environments.
Specifications of UNS S31803 Duplex Ferrule Fittings:
These fittings are manufactured from duplex stainless steel grades such as UNS S31803 and UNS S32205. Tube sizes typically range from 2 mm OD to 50 mm OD and from 1/16” OD to 2” OD. Thread types include BSP, UNF, ISO, NPT, SAE, and BSPT. Pressure ratings are generally in the range of 300, 1000, and 3000 PSI for duplex steel applications. Applicable service temperatures are typically between 150°C and 400°C, depending on operating conditions.
The standard configuration of UNS S31803 Duplex Ferrule Fittings includes tube-to-tube connections such as elbows, tees, crosses, straights, and bulkhead fittings. Tube-to-male configurations include male elbows, male connectors, and male tees, while female configurations include female elbows, straight connectors, and positionable fittings. Tube closure components include caps, plugs, weld connectors, and ferrule sets, available in various sizes and designs.
