ASME B16.5 UNS N06625 Inconel 625 Flange Set for Singapore Piping Project

Haihao Group has completed manufacturing, full non-destructive examination and shipment of a mixed batch of ASME B16.5 UNS N06625 Inconel 625 flanges for our Singapore client, covering blind flanges, socket weld flanges and weld neck flanges across multiple pressure classes and sizes.

This ASME B16.5 UNS N06625 Inconel 625 flange package spans pressure ratings from Class 150 up to Class 1500, with nominal sizes ranging from 1/2 inch to 4 inch, all built with raised face sealing surface. Different schedule thicknesses including Sch 40S and Sch 80S are supplied to match the client’s piping design load, a common requirement for high-corrosion process lines in Singapore’s chemical and offshore facilities.

Quality control for this ASME B16.5 UNS N06625 Inconel 625 flange batch follows strict client-specified inspection scope, far beyond standard commercial checks. Every flange undergoes PMI positive material identification with readable photos and formal reports, 100% ultrasonic testing, and full liquid penetrant examination. Beyond NDE, one intergranular corrosion test per heat lot is performed to ASTM G28 Method A, verifying resistance to intercrystalline attack for harsh corrosive service.

We separate and mark each heat number clearly during production and packing, so inspectors can trace test records, NDE certificates and IGC results easily on site. The RF face finish is controlled consistently to support reliable gasket sealing under fluctuating process pressure.

Many Southeast Asia end-users struggle to source fully tested ASME B16.5 UNS N06625 Inconel 625 flange assemblies with complete IGC documentation ready for third-party review. Haihao Group keeps stable forging capacity for Inconel 625 and can tailor inspection packages according to project specs, whether you only need standard NDE or mandatory corrosion qualification testing.

If you require ASME B16.5 UNS N06625 Inconel 625 flange, blind flange or weld neck flange with ASTM G28 intergranular corrosion testing for your upcoming piping project, send over your specification sheet to get a detailed quotation.
