ASTM B564 UNS N06625 WNRF Flange for Singapore Sour Service Delivery

Haihao Group has finished the packing and shipment of an ASTM B564 UNS N06625 weld neck RF flange for a sour service project based in Singapore. This NPS 2, Class 600, SCH10S flange is machined following ASME B16.5, built specifically for harsh sour environments where sulfide stress cracking control is non-negotiable.

This ASTM B564 UNS N06625 flange is supplied as NACE Grade 1 material, with full heat treatment arranged to lock in stable mechanical performance. Our QC team carries out 100% PMI analysis, with official test reports listing actual measured values of Cr, Ni, Mo and Cb/Nb. The unit also passes 100% LPE, UT and PT examinations before release, to rule out internal and surface defects.

Each ASTM B564 UNS N06625 flange carries required marking: NACE, PMI serial number and unique item code, plus origin mark Hebei Haihao, China. To protect the critical sealing face and weld end during sea transit, we fit end caps and wrap the flange with extra plastic film. The finished piece is secured inside a sturdy wooden case to avoid impact damage.

Sour service operators in Southeast Asia often struggle to source ASTM B564 UNS N06625 flanges with complete, verifiable test documentation. Our forging and machining workflow is set up to satisfy strict NACE MR0175 / MR0103 requirements, with full traceability from raw alloy bar to finished machined flange.

If you are looking for NACE-compliant Inconel 625 weld neck flanges or other nickel alloy piping components, send your size, class and inspection scope to our technical team, and we will prepare formal quotation and material certificates.
