The ASTM A694 F65 WNRF flange is a high-yield forged carbon steel component, favoured for high-pressure hydrocarbon lines across the Gulf region. Unlike ordinary A105 forgings, A694 grades are engineered specifically for pipeline transmission, with tighter controls over tensile, yield and impact performance. This unit carries a raised face sealing surface and butt-weld hub design, which helps distribute bolt load evenly and maintain reliable sealing under fluctuating operating pressure.
Heat treatment forms the core step to lock in the required mechanical properties of this ASTM A694 F65 WNRF flange. After forging and rough machining, the flange went through controlled thermal processing before final inspection. The mandatory impact test target is 33J at -29°C, a critical threshold that guards against brittle fracture during cold spells or rapid depressurisation events on site. Once test reports and dimensional checks passed review, the flange received a black protective paint coat before packing.
ASME B16.5 governs the dimensions, bolt layout and pressure-temperature rating for this ASTM A694 F65 WNRF flange. Our QC team cross-referenced flange thickness, hub profile, raised face finish and bolt hole pitch against the standard, alongside reviewing heat treatment records and Charpy test certificates. Full traceability documents are bundled with the shipment for the client’s internal review and third-party acceptance.
Haihao Group regularly supplies ASME B16.5 high-yield flanges for UAE, Oman and other Middle East pipeline contractors. We can produce A694 F52, F56, F60, F65 and F70 weld neck flanges, with custom impact test, heat treatment and coating options matched to project specifications.
