Use this route to understand what has to be confirmed before price, lead time, MTC 3.1 and third-party inspection commitments are made.
Material grade, heat number, certificate basis and substitution limits are checked against the High Pressure Flanges drawing or standard before procurement is released.
The forging route is selected around flange type, section thickness, bore allowance, hub or neck geometry and pressure-service requirements.
Heat treatment is planned with the required record package, mechanical testing basis and impact-test condition where low-temperature or alloy service applies.
Rough machining opens reference faces, bore, hub, neck or sealing-face stock needed to control allowance before final flange machining.
Final machining controls facing, bore, bolt pattern, groove, sealing surface and flange-table or drawing tolerances before dimensional inspection is issued.
Inspection covers dimensional report, MTC 3.1, PMI and required UT, MT or PT records before the release documents are matched to the purchase order.
Marking, packing and export documents are prepared by PO line item so the High Pressure Flanges shipment can clear customs and be identified at site receiving.
Include document requirements with the first RFQ so inspection cost and timing are visible before offer comparison.
Complete offers come back fastest when the first message carries the data below - and avoids the omissions that make quotations look cheaper than they are.
Short answers for common RFQ questions.
Yes. Send the latest drawing revision with material, quantity, tolerance, inspection and destination requirements so the RFQ can be checked before quotation.
A practical RFQ should include standard or drawing, size, pressure rating, material grade, quantity, inspection requirements and destination country.
Common requests include ASTM A105, A350 LF2, stainless steel, duplex steel and project-specified alloy grades, subject to drawing and service requirements.
MTC 3.1, dimensional reports, heat treatment records, PMI, UT, MT, PT and third-party inspection can be reviewed according to the project requirement.
