Haihao Group Ships ASTM B564 UNS N06625 Reducing Weld Neck Flanges to UAE

Haihao Group completed manufacturing and shipment of ASTM B564 UNS N06625 reducing weld neck flange sets for an oil and gas piping project in the UAE. This batch includes both RF raised face and RTJ ring type joint variants, machined in multiple pressure classes with SCH80S wall thickness, all built strictly to ASME B16.5.

Product Specification Table

Every ASTM B564 UNS N06625 reducing weld neck flange is forged from Inconel 625 nickel alloy and produced to meet full NACE compliance. Heat treatment was implemented for the whole forging batch, with corresponding coupon test blocks supplied alongside the flanges. Hardness testing confirmed minimum 210HBW, satisfying the client’s sour service material requirements.

The ASTM B564 UNS N06625 reducing weld neck flange order covers mixed size transitions and pressure ratings. Sizes range from 1″×1/2″ up to 2″×1/2″, with pressure classes of 150#, 300#, 600# and 1500#. We delivered RTJ flanges for high-pressure service and RF types for general process piping, matching different sealing needs on the same pipeline system.

Nickel alloy UNS N06625 offers excellent resistance to pitting and stress corrosion cracking, making this ASTM B564 UNS N06625 reducing weld neck flange well suited for the harsh sour and chloride environments common in UAE onshore and offshore facilities. Our QA team performed hardness verification and material traceability checks before release.

For UAE and Middle East project buyers requiring sour service fittings, sourcing ASTM B564 UNS N06625 reducing weld neck flange with heat treatment and test coupons simplifies third-party inspection and project acceptance. Haihao can produce custom reducing WN flanges with NACE compliance, full MTR documentation and PMI testing. Reach out to our engineering team to discuss your nickel alloy flange requirements.
