Nickel 201 Raised Face Flanges are forged low-carbon commercially pure wrought nickel flanges made from UNS N02201 / W.Nr. 2.4068 material, typically supplied to ASTM B564 material requirements and ASME B16.5 dimensional standards in pressure classes 150# – 2500#. Ragnar Metals & Tubes manufactures and exports these flanges with RF facing options, EN 10204 3.1/3.2 documentation, and third-party inspection on request.
Ragnar Metals & Tubes is a 201 Raised Face Flange Supplier and manufacturer of Nickel 201 (UNS N02201) raised face flanges to ASTM B564 and applicable ASME flange dimensional standards, with common sizes and classes available from stock, subject to current inventory, for export and EPC orders.
A raised face flange has its sealing face machined slightly proud of the bolt circle plane, concentrating gasket contact stress over a smaller area for a reliable seal — the most widely used facing type across the ASME B16.5 pressure classes. The raised face height and finish are standardized by ASME B16.5, and this facing type is compatible with the widest range of standard flat-ring or spiral-wound gaskets used across general industrial piping.
Nickel 201 is a low-carbon commercially pure wrought nickel (UNS N02201) known for the low carbon content prevents graphite-related embrittlement above roughly 315°C, making it the preferred nickel grade for high-temperature caustic service.
