This is a 1-inch nominal pipe size (NPS) flange designed and manufactured according to ASME B16.5 standards. It is rated for Class 600 service and features a Raised Face (RF) sealing surface. The flange is constructed from Inconel 625 (ASTM B564 UNS N06625), a nickel-chromium-molybdenum alloy known for its exceptional corrosion resistance, particularly in harsh environments.

This flange is also compliant with NACE MR0175/ISO15156, making it suitable for use in sour service applications where exposure to hydrogen sulfide (H2S) is a concern.
