Since the 1980's, we have been in the pursuit of creating a broad and complete set of wholesome products line that is a sustainable and profitable; which incorporates designs and features that accommodate requisites of diverse industries. We, Neo Impex Stainless Pvt. Ltd., an ISO 9001:2000 company strive to offer products that reduce cost and raise output. We are a manufacturer, supplier and exporter of Stainless Steel 347 / 347H Flanges that are austenitic flanges with traces of Niobium which thwarts the formation of Chromium carbides near grain boundary.
This, in turn, prevents intergranular corrosion. ASME SA182 SS 347 Slip-On Flanges are used with heavy wear exhaust systems and tubes connecting industrial boilers as they are resistant to high oxidation and impart greater toughness at cryogenic temperatures. Our SS UNS S34709 Weld Neck Flanges are manufactured with added Carbon for added toughness and refined high temperature creep properties in the aerospace, petroleum refining and high-temperature steam services. Also We offer wide range of Stainless Steel ASTM A182 347 Flanges such as SS 347 Slip On Flanges, SS 347H Weld Neck Flanges, SS 347 Socket Weld Flanges, SS 347H Blind Flanges, SS 347 Orifice Flanges, SS 347H Spectacle Blind Flanges, SS 347 Screwed / Threaded Flanges, SS 347H Reducing Flanges, SS 347 Ring Type Joint Flanges (RTJ) etc.
What is SS 347 Flanges?
SS 347 Flanges are flange fittings made from stainless steel grade 347, which is a stabilized austenitic stainless steel with the addition of columbium (niobium) and tantalum. These flanges offer excellent high-temperature strength and resistance to intergranular corrosion. SS 347 Flanges are commonly used in applications involving elevated temperatures, such as in thermal processing equipment, exhaust systems, and chemical processing plants.
What is 347 stainless steel flange used for?
347 stainless steel flanges connect pipes or fittings in various industrial applications requiring resistance to high temperatures and corrosive environments. They provide a secure and leak-free connection, allowing for efficient flow of fluids or gases in piping systems. 347 stainless steel flanges are commonly utilized in petrochemical, chemical, and power generation industries, where thermal cycling and exposure to corrosive substances are prevalent.
What is the difference between 304 and 347 stainless steel flanges?
The main difference between 304 and 347 stainless steel flanges is their chemical composition and stability. While both grades are austenitic stainless steels, 347 stainless steel contains columbium and tantalum, which provide stabilization against sensitization and intergranular corrosion at elevated temperatures. This makes 347 stainless steel flanges more suitable for high-temperature applications than 304, which are not specifically designed for such environments.
