Project completed

SASA FLANGE completed a batch of ASTM A182 Класс F22 600 weld neck flanges for elevated-temperature process piping. Final release covered material identity, heat-number traceability, твердость, размеры, facing condition and export protection before shipment.

Delivery highlights

Bore transitions were checked against the purchase schedule to support field fit-up.
Raised faces and weld preparations were protected immediately after acceptance.
Released items remained linked to heat numbers and EN 10204 3.1 documentation.

Manufacturing and machining scope

The F22 forgings were processed under the ordered material and heat-treatment requirements before final machining. Hub profiles, bolt drilling, gasket faces and weld ends were produced to the applicable ASME B16.5 dimensional envelope. The ordered pipe schedule was treated as a controlled input because a correct Class 600 flange can still create a field mismatch if the bore or weld preparation is wrong.

During production, heat identity followed the parts through machining and inspection. Permanent marking was applied in a location that remained legible after coating and packing without affecting the sealing surface or weld end.

Release inspection before shipment

PMI confirmed the chrome-moly alloy family, while hardness readings and material records addressed the delivered condition. Dimensional checks covered outside diameter, толщина, hub geometry, bolt-hole pattern, бурить, weld end and raised-face condition. These checks perform different functions and were reviewed together rather than using PMI as a substitute for mechanical or dimensional acceptance.

Following release, sealing faces received rigid protection and the flanges were separated inside the export package to prevent metal-to-metal impact.

Information needed for a comparable RFQ

A comparable inquiry should identify the exact material specification and grade, governing standard and edition, НПС, класс давления, тип фланца, лицом к лицу, диаметр отверстия или соответствующий график труб, quantity and destination. For this project-news scope, the key reference points were ASTM A182 F22 forged alloy steel, Приварная горловина, поднятое лицо (WNRF), Сорт 600 и NPS 2–12; bores matched to ordered pipe schedules.

State the required EN 10204 certificate type, heat-number traceability, PMI extent, пределы твердости, dimensional report, NDE method and acceptance standard, third-party witness points, packing method and required delivery date at quotation stage. Early definition allows manufacturing, inspection and document schedules to be reviewed together.

Часто задаваемые вопросы

Does Class 600 mean the flange is rated for 600 psi in every condition?

Нет. Allowable pressure depends on the material group and design temperature in the adopted ASME B16.5 rating table.

Why is the pipe schedule needed for a weld neck flange?

The schedule or exact wall thickness defines the required bore and weld-end transition for field welding.

Which documents accompanied the shipment?

The release package was prepared around EN 10204 3.1 материальные записи, heat traceability and the ordered inspection reports.
