Detailed Information
Dinesh Tube is one of the most prominent manufacturers and suppliers of Stainless Steel 347H Flanges. Our Stainless Steel 347H Flanges are of eight types Stainless Steel 347H Slip On Flanges, Stainless Steel 347H Weld Neck Flanges, Stainless Steel 347H Blind Flanges, Stainless Steel 347H Orifice Flanges, Stainless Steel 347H Socket weld Flanges, Stainless Steel 347H Threaded Flanges, Stainless Steel 347H Long weld Neck Flanges, Stainless Steel 347H RTJ Flanges, Stainless Steel 347H Reducing Flanges. Stainless Steel 347H Flanges are fabricated from austenitic stainless steel alloy including columbium and chromium. Therefore the presence of columbium helps in preventing resisting intergranular corrosion and carbide precipitation. Furthermore, it also includes tantalum content that exhibits higher creep and stress rupture. These flanges are often known from DIN 1.4961. 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. Stainless Steel 347H Socket Weld Flanges can be used in applications requiring repeated heating in the range of 800 Degree F and 1650 Degree F.
Stainless Steel 347 Weld Neck Flanges alloyed with columbium-tantalum (referred to as niobium) allows good mechanical properties at high temperatures.
All our Stainless Steel 347H Flanges conform to international standards and are manufactured according to ASTM, ASME, DIN, ANSI, EN, WERKSTOFFE, JIS, BS standards. Dinesh Tubes supplies a full range of specialized Stainless Steel 347H Flanges used for high-performance gas chromatography (GC) and liquid chromatography (LC) as components for chromatography columns used for analytical and preparative processes in diverse industries. Each piece of Flanges is fully tested by professionals according to international standards. Also available at best possible rates in the market.
