Super Duplex Steel UNS S32750 Tubes Manufacturer & Suppliers
Kalpataru Piping Solution is a leading manufacturer, supplier and exporter of the super duplex steel UNS s32750 Tubes that have been designed to perform at their best in highly corrosive and high-pressure conditions. This grade is a mixture of austenite and ferritic microstructures, which offers excellent mechanical strength, enhanced hardness, and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. The increased level of chromium, molybdenum and nitrogen ensures stability and longevity in the long run, even in seawater and severe chemical media.
Our tubes are seamless, welded, ERW and EFW tubes with tight precision and massive structural integrity. The homogeneity in seamless construction would also avoid the weak point at the welding and allow it to be used in offshore platforms, desalination plants, chemical processing, and heavy-duty oil and gas systems. The tubes are also suitable for providing great weldability, shapeability and toughness at high and cryogenic temperatures.
We also offer Super Duplex Steel UNS S32760 Tubes that come in different sizes, schedules and custom lengths to suit the different needs of industries. All tubes are checked for quality, pressure tested and corrosion tested to give the ultimate leak-proof and long service performance in the severe conditions of operations. Seeking a custom quote and engineering assistance for challenging offshore, desalination and high-pressure applications.
