Alloy 20 / 20Cb3 Flanges

Shree Viratra Enterprises is a member of the ISO. Since our incorporation in 1980, we have grown personally and professionally, developing new services, goods, and production methods. As a result, we are now manufacturing and exporting behemoth for metals like stainless steel, carbon steel, alloy steel, and other rare metals. We are producers of alloy 20-lap joint flanges, which have improved general sulphuric acid corrosion resistance and are crucial for mixing tanks and synthetic rubber manufacturing facilities. Being in the offshore and oil business is frequently attributed to their availability with pressure fittings (NPT), ASTM B462 Alloy UNS N08020 Blind Flanges that may be linked to a pipe or valve, equipment with a nozzle, and their resistance to acidic attack. We provide Alloy DIN 2.4660 Weld Neck Flanges, which have niobium added to reduce carbide precipitation during welding at high temperatures. These flanges are essential for pickling equipment and process pipes. We ship Alloy 20 Slip On Flanges following ASTM SB462, which are an affordable substitute for pricey high Nickel flanges. Because they are resistant to pitting and crevice corrosion, they are significantly less expensive than nickel-based alloys yet offer the same benefits. For further information, get in touch with us. Also, We offer a wide range of Alloy 20 ASTM B462 Flanges, such as Alloy 20 Slip On Flanges, Alloy 20 Weld Neck Flanges, Alloy 20 Socket Weld Flanges, Alloy 20 Blind Flanges, Alloy 20 Orifice Flanges, Alloy 20 Spectacle Blind Flanges, Alloy 20 Screwed / Threaded Flanges, Alloy 20 Reducing Flanges, Alloy 20 Ring Type Joint Flanges (RTJ) etc.
