Detailed Information
Dinesh Tube is one of the most prominent manufacturers and suppliers of Hastelloy UNS Flanges. Our Alloy UNS Flanges are of eight types Hastelloy UNS Slip On Flanges, Hastelloy UNS Weld Neck Flanges, Hastelloy UNS Blind Flanges, Hastelloy UNS Orifice Flanges, Hastelloy UNS Socket weld Flanges, Hastelloy UNS Threaded Flanges, Hastelloy UNS Long weld Neck Flanges, Hastelloy UNS RTJ Flanges, Hastelloy UNS Reducing Flanges, Hastelloy UNS Forged Flanges. Duplex S31803 Blind Raised Flanges finds applications due to both excellent corrosion resistance and high strength. Microstructures of Duplex S31803 Spectacle Blind Flanges consist of a mixture of austenite and ferrite phases. Duplex S31803 Socket Weld Flanges has pitting and crevice corrosion resistance superior to 317L austenitic stainless steel. Duplex S31803 Weld Neck Flanges combines good mechanical strength and ductility with moderate to good corrosion resistance in a variety of environments. Duplex S31803 Lap Joint Flanges is characterized by high yield strength and doubles that of the standard austenitic stainless steel grades.
Duplex S31803 Ring Type Joint Flanges contain larger amounts of chromium in comparison with other steels and thus have good corrosion resistance. Duplex S31803 Orifice Flanges describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely Ferritic, like 430 stainless. Alloy S31803 Pipe Flanges resists chloride environments and sulfide stress corrosion.
These flanges are provided in different sizes, dimensions and custom specifications to match diverse requirements of our domestic as well as global customers.
