ASTM A790 S32750 Super Duplex Steel Pipe Manufacturer, Supplier in Mumbai, India.

Piyush Steel is an established manufacturer, stockiest, supplier, and distributor of Super Duplex Steel UNS S32750 Pipes. Super Duplex Steel UNS S32750 Pipes is an austenitic-ferritic stainless steel that provides excellent resistance to pitting corrosion & crevice corrosion. The chemical composition, and a high chromium and molybdenum content, ensures high tensile strengths and exhibits high thermal conductivity and low thermal expansion. In both regards the characteristics of Super Duplex Steel UNS S32750 Pipes outperforms ordinary austenitic stainless steels. These pipes are intended for the application need exceptional strength and corrosion resistance. S32750 is comprised of molybdenum, chromium and nickel content. Higher composition of molybdenum and chromium and little addition of nitrogen results outstanding resistance to chloride pitting and crevice corrosion. However, the duplex structure offers good resistance to pitting and chloride stress corrosion cracking. Super Duplex Steel UNS S32750 Pipes should be limited to applications up to 316 degree C. Its service can be expanded up to elevated temperature but it can reduce corrosion resistance and toughness of grade. Super duplex structure has exceptional mechanical properties.

The duplex structure of pipes are highly resistive to uniform corrosion in organic acid containing acids such as acetic and formic acids. Additionally, it has exceedingly resistance to inorganic acids that contain chlorides. The ferritic structure of pipes is resistive to stress cracking in warm chloride conditions. These pipes are used in various industries such as Power Generation, Off-Shore Oil Drilling Companies, Petrochemicals, Gas Processing, Specialty Chemicals, Pharmaceuticals, Pharmaceutical Equipment, Chemical Equipment, Sea Water Equipment, Heat Exchangers, Condensers, and Pulp and Paper Industry. We perform a number of tests on our pipes to ensure high standard quality. The tests conducted are eddy current testing, hydrostatic testing or ultrasonic examination, NDT and also chemical and physical property inspection. Some of the other tests are chemical analysis, Mechanical test, Rockwell hardness test, chemical test, intergranular corrosion test, positive material test, flattening test, flaring test, and third-party inspection and so on. Customer satisfaction is our top priority and we strive to meet the same. Our highly qualified team of professionals strive hard to meet our customers’ needs and have thus received acclamations.
