Virgin Engineers are identified as a supplier of Duplex Steel S31803 / S32205 Instrumentation Tube Fittings. Due to its resistance ability, it finds use in a diverse range of engineering sectors. The microstructure of duplex steel has both austenitic and ferritic structures that enhance properties ideal for engineering applications. These are tube fittings that are designed by us considering the global standards and set industrial norms. This grade is tougher and stronger than standard austenitic steel. These tube fittings are made with tested and superior quality crude materials that offer good resistance to local and general corrosion. We suit up the advanced technology and equipment to whirl production that meets and exceed the requirements of the customers.
Duplex Steel S31803 Instrumentation Tube Fittings:
The duplex steel has a microstructure having a 50/50 austenitic and ferritic structure named UNS S31803 in a unified numbering system. It has higher mechanical strength and higher ductility. It has higher corrosion resistance in different cyclic environments ranging from moderate to higher concentric environments. These tube fittings can be operated in pitting and crevice corrosion environments. Moreover, these tube fittings have a good ability to resist stress corrosion cracking, ranging from nominal to sub-zero temperatures. Therefore, S31803 Duplex Stainless Steel can successively be used on the behalf of standard grades where higher mechanical properties are needed. The welding and machining of these tube fittings don’t show any particular problems.
Duplex Steel S32205 Instrumentation Tube Fittings:
Duplex Steel S32205 is high strength and corrosion resistance duplex steel instrumentation tube fittings widely used in chemical processing and petrochemical plants. UNS S32205 is the numbering of this grade in the unified numbering system. For a long time aging exposure can inflame weakening and embrittlement of corrosion resistance in the temperature up to 475 deg C. At the same temperature, the aging process works as a heat treatment that enhances resistance ability. Due, to this operation other features, may decrease. Before the annealing and heat treating process it is analyzed. It is induced in the aging process to achieve a higher hardening level with a decrease in ductility. It has a higher work hardening rate than standard grades. This grade has also a ferritic and austenitic structure that is ideal for industrial applications. This grade replaces the heavy and bulky options from industrial applications. The higher reliability of these instrumentation tube fittings is due to the excellent combination of mechanical properties, toughness, and resistance ability.
Duplex Steel S31803 / S32205 Instrumentation Tube Fittings are tested under different testing measures to ensure their reliability and functionality in adverse applications. The test procedure checks the overall strength of tube fittings. Those tests are hardness test, IGC test, pitting corrosion test, chemical test, mechanical test, tensile test, radiographic test, destructive test, and macro test. Micro tests, ultrasonic tests, compression tests, pressure tests, leakage tests, and non-destructive are also performed by us. In order to deliver these tube fittings in damage-free mode, we use high quality standard packing techniques. It is covered by a thin film of plastic to add prevention from rusting.
