Delivery highlights
Controlling large-diameter flange interfaces
For NPS 26 and larger flanges, the order description identified ASME B16.47 and the required series. The series affects outside diameter, bolt circle, hole pattern and related dimensions, so it cannot be inferred after machining. Weld neck bores and end preparations were also checked against the connecting pipe wall and field welding plan.
Large components require staged dimensional inspection because small angular or drilling errors can become significant at the mating interface. Approved drawings and calibrated measurement tools were used as controlled references.
Handling, inspection and delivery controls
Identidad material, hardness and UT requirements were reviewed with the heat and production records. Final inspection included sealing faces, bolt holes, flange thickness, hub profile, bore and marking. Lifting and handling points were planned to avoid using machined surfaces.
Rigid face covers, separation blocks and crate bracing prevented flange-to-flange contact during road, port and ocean handling. Package weights and lifting information were marked for the receiving team.
Information needed for a comparable RFQ
A comparable inquiry should identify the exact material specification and grade, governing standard and edition, NPS, clase de presión, tipo de brida, frente a, diámetro interior o tabla de tubería correspondiente, quantity and destination. For this project-news scope, the key reference points were ASTM A182 F11 and F22 alloy steel, Weld neck and blind, Class 150–600 y NPS 26–48.
State the required EN 10204 certificate type, heat-number traceability, PMI extent, límites de dureza, 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.

Preguntas frecuentes
What is the main purchasing difference between ASME B16.5 and B16.47?
ASME B16.5 covers NPS 1/2 a través de 24, while B16.47 covers large-diameter NPS 26 a través de 60 and requires a Series A or Series B choice.
Can Series A and Series B flanges mate directly?
They use different dimensional systems and generally should not be assumed interchangeable. Confirm the exact mating interface.
Why is special packing needed for large flanges?
Their mass and exposed faces increase the risk of impact, distortion and handling damage during international logistics.
