Stainless Steel 304 Flanges
ASTM A182 f304 flange Manufacturer, View SA 182 F304 Pipe Flange Sizes & Schedule
Stainless Steel 304 Flanges are some of the most widely used flanges of all. Dinesh Industries is a manufacturer and supplier of 304 grade stainless steel materials including flanges. We offer a wide range of flanges in this grade and in different types as well. Our SS 304 plate flange is a metallic ring that is used to add to the attachment surface at the end of a pipe. Since the 304 material is strong and has an extent of corrosion resistance, it is suitable for more general service applications. Also, the pricing is very cheaper, these are used widely. The a182 is a specification for fittings in the 304, 304L and 304H grades of steels.

The ASTM a182 f304 flange therefore has the advantages of cost effectiveness, strength and corrosion resistance. The ASME sa 182 f304 pipe flange types can vary. There are socket weld, weld neck, slip on, lap joint and threaded flanges. The f304 blind flange is different from all other types in that it is not used to connect two pieces together. Rather, it is applied to close a pipeline. The UNS S30400 flange is made up of this 304 chromium nickel alloy and we can cater any order of 304 stainless steel flanges. You can contact us for more information.
