Stainless Steel 304L Flanges are made up of a lower carbon version of the chromium nickel austenitic stainless steel that is suitable for excessive welding applications. R.C. Metal Corporation is a leading manufacturer and supplier of the ASTM A182 Grade F304L Pipe Flanges in various shapes, scales and dimensions. The 304L flanges are made according to the ASTM A182 specifications which specify components for pressure vessel services. The ASTM A182 F304L Flange can operate under high temperatures up to 870 degrees Celsius with high pressure capacities. There are different pressure classes of the SS 304L Slip On Flanges.
Stainless Steel 304L Flanges
The slip on flanges are mostly used with the seamless pipes and there are 150 through 2500 pressure classes. The pressures are also measured with pressure numbers ranging from PN6 through PN64. The 304L Stainless Steel Flanges create less carbide precipitation while welding and therefore they reduce the intergranular corrosion and localized corrosion. The SS 304L Blind Flanges are used with pipes where the connection has to be closed. There are different types such as the welded neck flanges and the socket weld flanges; all having different application purposes.
The UNS S30403 Pipe Flanges are used in a variety of industries ranging from pharmaceuticals to petrochemicals, oil and gas, food processing, heat exchangers and power generation plant applications. There are different design models such as the 304L SS Lapped joint Flanges which have a lap joint in them which is often used with a stub end. The flat face, raised face and ring type joints are also available. The Stainless Steel 304L RTJ Flanges have the ring type joint. The flange comes in two halves as rings and is welded with pipe ends and then one another to make a better connection. Please feel free to contact us for a full product catalog and pricing.
